June 2004 DelphMap™ User's Manual CHAPTER 1 Getting Started with DelphMap Software Installation Notes Typical software installation CD may contain folders like the ones depicted in the Windows Explorer layout. (See the figure, Typical listing of TEI software installation folders ’) FIGURE 1.
June 2004 DelphMap™ User's Manual TEI software is compatible with Windows NT 4.0, Windows 2000, and Windows XP. The following notes will help you achieve a smooth installation of the software. • Please exit from all other applications before running any of the installation programs. • You will not be able to complete the installation on an NT4.0 or Windows 2000 system if you do not have administrator’s rights. All Isis “black boxes” ship with a user name Isis.
June 2004 DelphMap™ User's Manual • The TEI manuals that are installed with the software are in Adobe Acrobat PDF format. Acrobat Reader software (required to read the PDF files) is also on the CD. • The CD has a number of other folders containing drivers and applications that could be required; each folder has a text file with more information. • To remove the software, use the Add/Remove Programs utility in the Windows Control Panel collection of utilities.
June 2004 DelphMap™ User's Manual FIGURE 2. Modify, Repair, Remove choices during installation You will need to remove the old version of the software before you will be permitted to install the new version. To do so, enable the Remove button in the dialog box and click Next. You can then install the new version by rerunning setup.exe. As noted above, some items are deliberately not removed during the uninstall process; doing so can cause problems.
June 2004 DelphMap™ User's Manual Solutions to Some Common Problems Problem: Solution: Problem: Solution: Problem: Solution: Problem: Solution: Problem: Solution: Problem: After about five minutes the installation does not complete and the Windows desktop does not return. Try again after using + to shut the system down and restart. The problem can be caused by applications running in the background or not being shut down before running the installation.
June 2004 DelphMap™ User's Manual Solution: Consider using the Minimum Installations option located on the CD to install only the programs you need. Problem: When first running Isis after installing a new version, you receive an error message that says your Isis CFG configuration file is out of date. This message alerts you that CFG files created with versions of Isis earlier than this version of Isis are incompatible. Click OK to accept the message.
June 2004 DelphMap™ User's Manual With the Summer 2001 release of TEI software, some DLL names changed to avoid conflicts with other non-TEI applications. The DLLs that conflicted were: map.dll and splash.dll. If you are upgrading from the Fall 2000 release of TEI software, delete map.dll and splash.dll from C: {Windows Folder}\TEIDlls. Note: {Windows Folder} is the folder on your system where the Windows operating system is installed. For example, C:\WINNT, C:\Windows are {Windows Folder} types.
June 2004 DelphMap™ User's Manual 4. When the installation completes, re-boot your PC. 5. When the system restarts, Norton Auto-Protect will be re-enabled by default. What DelphMap Does Starting with one or more files DelphMap recognizes ‘File Types in DelphMap’), DelphMap displays one or more “layers” of multiple, geocoded sonar imagery, or color-coded DTM (Digital Terrain Model) imagery, and bathymetry contour vector graphics.
June 2004 DelphMap™ User's Manual *.PCM *.SHP Pulse Code Modulation photo image file ESRI® ArcView Shape files. Types of files that can be imported directly into a DelphMap project: *.CON *.DDS_VOB Contact files generated by Target or TargetPro. Vector layers, along with a DDS_VIF file containing a visual image. *.DXF Seabed Classification files generated by SeaClass (an instance of a DXF file). *.SPN Span files generated from the Pipe Tracking module in Isis. *.TIF,*.BMP,*.
June 2004 DelphMap™ User's Manual 1. In Windows Explorer, create a parent folder (directory) to hold your DelphMap project (DMP) file. 2. In Windows Explorer, create child folders — one for each type of file and/or layer to be inserted/imported. For example, you might create a subfolder for your contacts, a subfolder for your bathymetry and/or side-scan sonar files (DDS_VIF), another for your XTF files, one for your DXF files (if any), and so on.
June 2004 DelphMap™ User's Manual 7. One at a time, import file(s) or insert whatever layers will be part of your project. Specify one of the previously created and appropriate child folders to hold the contents of the layer or file. If you are adding layers to your project, make sure that the layer names you assign to them are unique. See ‘Working With Layers Inserted into a Project File’.
June 2004 DelphMap™ User's Manual DelphMap displays a dialog box where you can specify a project file to open. 2. Specify the file name by either typing it or browsing for it from this dialog box. To save a project file • From the DelphMap main menu, click Save or Save As… If you click Save, the system saves your project as it currently is displayed, without further prompting. If you click Save As…, the system prompts you for a file name.

You also can create custom names for features by typing over the currently highlighted name in the box and then pressing . Project Files Window Area 3 of Figure 4.
June 2004 DelphMap™ User's Manual Main Display Window Area 5 of Figure 4. The largest area of your DelphMap application window, the Main Display Window contains the large view and detail of your map. The window can be resized but not moved, docked, or redocked from its initial position (see ‘Customizing the Work Space’). Overview Window Area 6 of Figure 4. Shows a thumbnail of the image layers. The size of this image remains constant even if you zoom in our out of the image in the Main Display Window.
June 2004 DelphMap™ User's Manual see the separate technical manual, Using DelphNav, provided by Triton Elics International, for the functionality of this part of DelphMap. Customizing the Work Space From the View menu, all visible parts of the application window, except for the main display area, can be turned on or off by placing a check mark next to the named view. By default, all viewable items are initially displayed, and thus all the choices in the View menu initially have a check mark next to them.
June 2004 DelphMap™ User's Manual Chapter 2 Icons and Display Tools Using icons and other display tools, DelphMap has several controls for working with imagery. This chapter explains those controls. The Toolbar Icons Most of the display manipulations can be done conveniently from icons appearing in a toolbar underneath DelphMap’s main menu. Many of the functions represented by the icons are also available as text choices from DelphMap’s menus. Most icons are unique to DelphMap.
June 2004 DelphMap™ User's Manual Zoom In The Zoom in function magnifies the image in your main display area by a factor of two and moves the image away from the midpoint of the main display window by twice the distance from the current position. Keyboard shortcut: [Num] [+]. Note: It is possible to zoom your image beyond the edges of the main display window, where you won’t be able to see it.
June 2004 DelphMap™ User's Manual function, click the icon again to return the icon to a non-selected state. (Choosing a different icon also deselects this icon.) Pan Use the Pan function to reposition the imagery in your main display window. After clicking the icon, left-click your mouse or trackball in your imagery and then draw a line in the direction you wish to move the image — the longer the line, the greater the shifted distance of the image in the display window.
June 2004 DelphMap™ User's Manual Drawing Line Types If you have enabled the Edit/Save a Digit function, you can then choose a line drawing tool shown here. Reading from left to right, the drawing tools are: draw a polyline, draw a point, draw a rectangle, and detect image regions. All line types are mutually exclusive to each other.
June 2004 DelphMap™ User's Manual 3. Select (or create) a label to be associated with the points or lines you intend to draw, which you can do from the Feature Selection Box (see page 18). If you drew a polyline or polygon, right-click after you’re through drawing the point or shape; doing so displays a menu of these choices: Save; Edit Object ; Delete Point; Close object; Quit; Delete Object; Copy; Paste. Choose one of those actions. 4. Choose one of the drawing line types from the Tools Palette. 5.
June 2004 DelphMap™ User's Manual FIGURE 5.
June 2004 DelphMap™ User's Manual Measure Tool The Measure tool function enables measurement of range and bearing between points on the image. When you left-click and draw a line in the main display window, DelphMap displays the imagery’s distance and heading in the last two frames of the Position and Distance window. The reported values are “sticky”; that is, they remain displayed until you click again in the image to establish a new distance and heading.
June 2004 DelphMap™ User's Manual Metric and Geographic Grids Clicking this icon displays a dialog box for two types of gridding — metric or geographic — each of which can be set independently of one another (or not set at all). The keyboard shortcut is . • When geographic gridding is enabled, DelphMap superimposes a geographical grid over your imagery. Grid intervals are in seconds. • When metric gridding is enabled, DelphMap superimposes a metric grid over your imagery.
June 2004 DelphMap™ User's Manual Bathymetry Processing If you have purchased the BathyPro utility from Triton Elics International, this BathyPro icon is enabled. Clicking it summons the DelphMap-BathyPro application where you can process, either interactively or in batch mode, single beam and multibeam data, resulting in output of DDS_VIF or DXF files that can be re-imported into DelphMap for more processing.
June 2004 DelphMap™ User's Manual icon, the Cross Cursor icon, the Metric and Geographic Grid icon, and the Color Palette icon also are examples of additional display aids. General Settings Menu from Main Menu From DelphMap’s main menu you can summon dialog boxes where you can specify settings affecting imported files, colors to be used in displaying various objects in DelphMap and settings to be applied to 2D and 3D Contacts. Such settings apply to all layer types.
June 2004 DelphMap™ User's Manual Settings for Tools A dialog box for tools settings for can be reached from the main menu via Settings→Tools or by choosing Settings→All Settings and then selecting the Tools tab. Figure 6 shows the dialog box as selected from the Tools tab of the All Settings menu. FIGURE 6.
June 2004 DelphMap™ User's Manual From the Browse buttons ( ) next to any of eight objects associated with the DelphMap application window, you can change the colors to be associated with the objects, as Display the Cursor in the Overview Window, and Synchronize Map Scale and Position Display the Cursor in the Overview Window means that cursor activity also appears in the Overview Window if the Turn Cursor On/Off icon is enabled in either the Overview Window or the Main Display Window.
June 2004 DelphMap™ User's Manual FIGURE 7. 2D Contacts dialog box Confidence Radius. When a contact is imported, or generated from within DelphMap, a circle is drawn around the target position. The radius of this circle represents theh confidence the user has in the target’s position. The default radius is 3 meters. Circles of different radii are possible in the same DelphMap project.
June 2004 DelphMap™ User's Manual Folder name to store geocoded image. When importing a contact, the user has the option of creating a geocoded image of the contact. A geocoded image looks something a mini-mosaic of the contact. You need to specify where to store these files; the default directory is the directory where the DelphMap executable file (.exe) is found, or the last directory set from a previous DelphMap project.
June 2004 DelphMap™ User's Manual FIGURE 8. 3D Contacts dialog box Displaying 3D contacts can be memory-intensive. If you get a DelphMap message that says you don’t have enough memory to view your imagery three dimensionally, adjust the northing and easting extensions in the 3D Contacts Size fields of the 3D Contacts dialog box to use smaller extents. The default size is 10 meters.
June 2004 DelphMap™ User's Manual Settings for Pipe & Span Tracking You use the Pipe Span Tracking tab of the DelphMap Settings dialog box to choose the color scheme for three parameters affecting pipeline objects found in imagery: Exposed, Half-Buried, or Buried. From the Pipe Span ) next to a parameter to get a Tracking tab, click a Browse button ( table of colors from which you can choose a color to be associated with that parameter; then click OK to set the color. Figure 9 shows the dialog box.
June 2004 DelphMap™ User's Manual Reset to Factory Settings If you are experiencing unexpected behavior from DelphMap, consider choosing Reset to Factory Settings as a way out of the difficulty. If you choose this, any settings you may have established in DelphMap during this session or a previous session are overridden by the original factory settings.
June 2004 DelphMap™ User's Manual FIGURE 10. File(s) tab area of the Settings box for vector layers To set properties for contact objects and their labels 1. Right-click on a vector layer name of a contact type in the Project Files window. 2. Choose Properties . The system displays the Settings dialog box, with the File(s) tab in the foreground (Figure 10). 3. Click the Settings tab in the Settings dialog box. The system displays the Settings tab area of the Settings dialog box (Figure 11).
June 2004 DelphMap™ User's Manual Green check marks initially appear in boxes indicating that whatever properties are specified here will be set for objects and labels. If you click on a green check mark, it turns to a red "X" indicating that you will be suppressing that option in your imagery. Clicking a box again reverses this action. In the Object color area, you can set the properties for Objects color, Line Style, Point Symbol, and a Region Fill Pattern.
June 2004 DelphMap™ User's Manual You can suppress or enable those colors, independently of each other, although it is advisable to make the Objects color and Labels Color match; that way, it will be easier to distinguish objects and their labels in your imagery. Also, if you are enabling an object and/or its color, it’s a good idea to increase the Font Size so that the labels are easily readable in the imagery. We recommend a Font Size setting of 10.000000 m. 4.
June 2004 DelphMap™ User's Manual FIGURE 12. Settings dialog box for a digit type of vector layer In the Settings tab area of the dialog box (example shown in Figure 12), you can modify the properties for the digit layer by changing the colors of the digit’s object and its labels, by giving the object a different line style, by assigning a region fill pattern, and by specifying a font size. Each of these properties can be set independent of the other properties. 4.
June 2004 DelphMap™ User's Manual To assign colors to labels or objects in layers 1. Right-click on a vector layer name in the Project Files window. 2. Choose Properties . 3. Click the Settings tab in the Settings dialog box. 4. Click the right-pointing marker (►) next to an Objects color or Labels Color you wish to change. The system displays a Color dialog box (Figure 13) containing a matrix of 48 basic colors and 16 uncolored boxes reserved for custom colors that you can define. FIGURE 13.
June 2004 DelphMap™ User's Manual For each of the remaining layers whose colors you wish to change, repeat the procedure ‘To set properties for contact objects and their labels’ and the procedure ‘To assign colors to labels or objects in layers’. When you have finished doing that, the seabed classification objects you imported into your imagery displays fully labeled and colored as you specified. Figure 21 shows an example of this treatment.
June 2004 DelphMap™ User's Manual Chapter 3 Importing and Exporting DelphMap can import a number of different types of files as layers to form imagery. DelphMap can also export layers as a single file, making the result easy to work with as a single entity. Importing Files of Different Resolutions Files of different resolutions can be imported into DelphMap. These include bathymetry, mosaic images and seismic profiles. For example, a mosaic image file with a resolution of 0.
June 2004 DelphMap™ User's Manual The geodesy information might be available to you a number of ways: It might be a text file specifying the corner coordinates and the resolution (size of each pixel). Or you might have a TFW (ArcView world file) or KAP (BSB format header file). Or the geodesy may be embedded in the header of a TIFF image you wish to import. In the latter case, the image is a true GeoTIFF. In the case of a true GEOTIFF image, DelphMap will not need any further information.
June 2004 DelphMap™ User's Manual FIGURE 14.
June 2004 DelphMap™ User's Manual In order to position any bitmap correctly in a project, your file to be imported must contain the information shown in Table 1. TABLE 1.
June 2004 DelphMap™ User's Manual Note: Even when the position is in latitude and longitude, you should also check the datum. Usually this will be WGS1984, but it might be different and could cause an error in the position. Also, if the value of “Pixels/Inch” for the image is set to 100, then the image will look wrong, both in the preview and when it’s imported. The only cure for this problem is to import the image into another application (PaintShop, Paint, etc.

Once the 2D contact settings have been selected, from the main menu of DelphMap, choose Project→Import→Import Contact... or right-click on anything in the Project Files Window. 3. The system displays an Open file dialog box where you can select one or more file names to be opened. From a single directory, specify the name or names of the contact files you wish to import. Click Open. 4.
June 2004 DelphMap™ User's Manual FIGURE 20. Imported 2D Contact To import a Contact directly from Target or TargetPro 1. Before importing a contact or contacts, go to the main menu of DelphMap and choose Settings→2D Contacts to set up how the contacts will be imported. The setup includes whether or not to create a geocoded image, where to store the geocoded image, selecting the input geodesy, and choosing the size of the confidence radius. See Figure 19, the 2D Contacts dialog box.
June 2004 DelphMap™ User's Manual For more information on each option, see Additional Display Aids, General Settings Menu from Main Menu. 2. From within TargetPro, go to Tools→Configuration and put a check mark in the Miscellaneous box labeled Import Saved Contact in DelphMap. Be sure DelphMap is open with the proper projection. 3. From within Target, when you select F9 or File→Save, you will have the option of checking a box labeled Display this contact in DelphMap.
June 2004 DelphMap™ User's Manual The system displays the image of the contact and its annotation dialog box, complete with quantitative data for several kinds of parameters that pertain to the contact. For the fullest documentation covering the Target software utility, refer to the Isis Sonar User’s Manual, Volume 2, and refer to the Using TargetPro user’s manual. FIGURE 21.
June 2004 DelphMap™ User's Manual Isis Echoing to DelphMap This function echoes cursor selections in Isis to DelphMap. When a user left-clicks anywhere in the Isis waterfall window, not only is the Isis Cursor information updated, but markers are placed in DelphMap at the corresponding position. These echo markers, in the shape of blue crosses, appear in DelphMap, providing DelphMap is open and a projection established.
June 2004 DelphMap™ User's Manual FIGURE 22. Imported DXF classification file example Areas of the imported classification are shaded to show differences. You can have DelphMap bring out more detail in the imagery, show the labels for the various seabed aspects, and assign colors to those labels by manipulating the properties of the various layers. You make these changes one layer at a time. See ‘To assign colors to labels or objects in layers’ for the technique of changing a layer’s colors.
June 2004 DelphMap™ User's Manual FIGURE 23. Classification file fully labeled and colored — example A seabed classification file imported and color-coded this way will display its seabed objects cleanly differentiated from each other. Notice that this method reveals more information than the technique of just importing the single DXF file as a layer (but not as a classification file).
June 2004 DelphMap™ User's Manual FIGURE 24.
June 2004 DelphMap™ User's Manual Importing an ASCII Point or Line File Importing an ASCII file of points with or without labels into DelphMap is done through the Digit toolbar. These imported points are then associated with the Digit layer. Changes to symbols and colors can be done through the Vector→Properties settings. See ‘Setting Properties for a Digit Type of Vector Layer’. To import an ASCII file of points with labels 1.
June 2004 DelphMap™ User's Manual 5. Define the X and Y positions and units. Then click OK. FIGURE 26. ASCII file importation setup dialog box 6. You will then be asked to define the geodesy of the ASCII file. The projection of the ASCII file must be the same as that of the DelphMap project. 7. Once the points have been entered, you can change the point symbols and colors with the Digit→Properties. See ‘Setting Properties for a Digit Type of Vector Layer’.
June 2004 DelphMap™ User's Manual To import a line from an ASCII file • To import a line defined by ASCII points, the method is the same as to import ASCII points with labels, only the ASCII file format is as follows: Label X, Y X, Y X, Y (If no label is required, omit the label in the ASCII file.) The ASCII line can have up to 1000 points. Importing a Seismic Profile See the Triton Elics International technical manual called Using SGIS.
June 2004 DelphMap™ User's Manual FIGURE 27. Merge layers dialog box, initial display 2. In the Files to merge panel, CTRL-click on two or more files to merge, thereby selecting them. You can also click the Select all button to include all listed files to be part of the merged file. Clicking Clear all unselects any selections already made. 3.
June 2004 DelphMap™ User's Manual the merged results to your working directory if you do the merge operation. It is that file which can be exported to another application. The system names the saved merge file using the format Mergen.DDS_VIF, where n starts at 1 and increments by 1 for any additional merge operations you perform in this project.
June 2004 DelphMap™ User's Manual You’re ready to merge your files after you have selected the total number of lines and the options to be applied to them. 4. Click Merge in the Merge layers dialog box to merge your files. The system displays a dialog box (Figure 28) prompting you to supply a layer name to contain the merged files. FIGURE 28. Merge layer name prompt dialog box 5. Click OK after supplying an appropriate layer name to hold the merged files.
June 2004 DelphMap™ User's Manual Exporting a Layer as a File Any layer you have imported into DelphMap can be exported out of DelphMap as a TIF or DXF file. If you’re exporting from an image (raster) layer, DelphMap can save the exported layer as a GeoTIFF or TIFF file. If you’re exporting from a vector layer, DelphMap can save the exported layer as a DXF or SHP file. The exported file can then be imported into any application capable of reading, and perhaps editing, the file. To export a layer 1.
June 2004 DelphMap™ User's Manual simultaneously saves two files: a TIF version of the layer and a supporting TFW file. The latter is known as a world file which contains the geo-referencing associated with the TIF file. Please refer to Chapter 8, ‘TIFF and GeoTIFF Differences’, for a more expansive discussion of this topic. The TIF or DXF file thus saved can now be opened in applications capable of reading the saved file.
June 2004 DelphMap™ User's Manual Chapter 4 Managing Layers DelphMap has several controls for manipulating displayed imagery. This chapter explains those controls and how to print your DelphMap image. Finally, this chapter explains some of the issues about GeoTIFF, which is one of the georeferenced imagery file types that can be exported from DelphMap.
June 2004 DelphMap™ User's Manual unchecked, the layer is hidden until rechecked. View Layer windows, if any are open, are unaffected by checking or unchecking. • Map Layout From this function you can assign a title and subtitle to the currently displayed image in DelphMap. You can also set the scale to be used for printing and set a map rotation for printing, if desired.

June 2004 DelphMap™ User's Manual Loading, Viewing, and Moving Layers As already noted, DelphMap can process and display bitmapped, vector aspects, and ASCII DXF forms of your imagery, if these are present. You need to load each aspect explicitly before DelphMap can do anything with them. This task is called inserting layers into the project file. Inserting a layer is the most basic thing you can do in DelphMap.
June 2004 DelphMap™ User's Manual Which version of the dialog box you get depends on the contents of the layer you are inserting. For the fuller version of the Specify a Layer Name dialog box, the upper Layer Name portion of the dialog box suggests a layer name to be associated with the file you are inserting. The lower Layer Name portion of the fuller dialog box contains a spin box (▼) of layer types that could be associated with the layer name.
June 2004 DelphMap™ User's Manual 4. Click OK in the dialog box after you have provided the layer name information. DelphMap inserts the layer into the Main Display Window and updates the Project Files Window with the layer name and the file name associated with it. Figure 36 shows an example of this. FIGURE 36.
June 2004 DelphMap™ User's Manual To insert a non-DelphMap file as a layer 1. Choose Project→Insert layer(s) from the main menu (or right-click on the project name in the Project Window). DelphMap displays a dialog box where you can browse or type a file name. 2. Choose a file type appropriate to your needs. Your choices are: • • • ASCII AutoCAD Files (*.DXF) QTC files (*.CLA) ESRI ArcView shapefiles (*.
June 2004 DelphMap™ User's Manual If you are inserting a SHP file, DelphMap displays a dialog box where you can specify which field in the SHP file shall be used to create a label to be associated with your DelphMap imagery (Figure 37).

June 2004 DelphMap™ User's Manual Identifying Mosaicked Images When an XTF file is mosaicked in Isis, several files are generated: • Filename.DDS_VIF. This is the mosaicked imagery and can be imported directly into Del_phMap. • Filename_track.DDS_VLB • Filename_track.DDS_VOB • Filename_track.DDS_VTX These are vector files that are created from the sensor’s navigation information. When imported into DelphMap a trackline is drawn with the file name as a label.
June 2004 DelphMap™ User's Manual Layer Manager The Layer Management dialog box is evocable from three locations: an on the toolbar, through the Tools menu, and through the menu icon options when right clicking in the project window. When Manage Layers is activated, the adjacent dialog box opens. There are individual tab windows for each layer type (i.e. image and vector). Only those layers that are present in the project will appear in a tab.
June 2004 DelphMap™ User's Manual Change file position by clicking the corresponding up/ down arrow icon, , or dragging and dropping one or more layers in the list itself. Multiple layers can be selected by holding down the or and clicking on the layers. Once a layer status has changed, the user can select the Apply button to preview the changes in the Project Display Window. The user can also click the Cancel button to lose all changes made in the Manage Layer dialog box.
June 2004 DelphMap™ User's Manual 3. While moving your cursor in the cursor value layer, observe that the Position and Distance Window reports the present depth of the layer at your cursor’s position. Figure 40 shows an example of a layer name designated as a cursor value layer and the depth reported in the Position and Distance Window.
June 2004 DelphMap™ User's Manual FIGURE 40. Cursor value layer example, reporting depth at cursor Note: Although it is possible to have DelphMap designate a sidescan layer as a cursor value layer, it is meaningless to do so, since sidescan layers do not have depth. Only bathymetry layers have the property of depth, so only bathymetry layers can show depth in the Position and Distance Window.
June 2004 DelphMap™ User's Manual is dominant and subordinate layers cannot shine through. This is the DelphMap default. • Shinethrough – Min: The lowest value of all pixels falling within a grid cell are used. Consequently, features in the imagery that were ensonified from weak or soft sonar returns have more opportunity to “shine through” layers. • Shinethrough – Average: The average value of all pixels falling within a grid cell are used.

June 2004 DelphMap™ User's Manual Chapter 5 Working with Three-Dimensional Contacts You can get an approximate three-dimensional model of selective parts of your DelphMap imagery by double-left-clicking on any part of a side-scan or bathymetry layer. The significance of this is that if you have both sidescan sonar imagery and topography imagery from bathymetry layer present in your project, the sidescan sonar imagery can be “draped” over the bathymetry layer.
June 2004 DelphMap™ User's Manual To make a three-dimensional contact • Double-left-click in your imagery. A three-dimensional image of the area that you clicked on appears in a separate three-dimensional Contact window. Figure 44 shows an example of a three-dimensional contact.
June 2004 DelphMap™ User's Manual FIGURE 44. Three-dimensional contact with light source position The hypothetical light source used to generate the image of Figure 44 is represented by the big white disk in the picture. A solid surface representation, with the light source revealed, is the DelphMap default for viewing threedimensional contacts. A compass indicator reveals the directional orientation of the displayed image.
June 2004 DelphMap™ User's Manual TABLE 2. Icon Three-dimensional contact icons, meanings Icon’s ‘Tool Tip’ Identity and Meaning Snapshot: If you click this icon, DelphMap: creates a snapshot of the current three-dimensional contact image, saves it to your working directory in the format indicated in your threedimensional Settings dialog (See ‘To change settings for threedimensional contacts’), and displays a copy of the saved image in the three-dimensional contact window.
June 2004 DelphMap™ User's Manual Decrease the Vertical Scale: This de-emphasizes the highs and lows of the undulations being used to represent the three-dimensional model. If the terrain being shown in your three-dimensional contact is especially rugged, this icon can help you “tame it down” so that you can see more details in the imagery Switch the Light On/Off: Click this icon to turn the light source on or off. The three-dimensional view of the image is retained whether the light source is on or off.
June 2004 DelphMap™ User's Manual FIGURE 45. Snapshot taken of a three-dimensional contact Through combinations of keystrokes and pointer clicks, you can manipulate your three-dimensional contact in a number of ways: • If you left-click and drag your pointer in any direction: The threedimensional contact rotates about its Y-axis. The Y-axis is temporarily displayed during the movement. (Initially, the point of intersection of the Y-axis into the imagery is centrally placed.
June 2004 DelphMap™ User's Manual • If you hold down the key and drag with your trackball’s or mouse’s left button: Both the light source and the imagery rotate synchronously about the Y-axis in the direction that you drag. The size of the imagery does not change during this movement. Imaginary arcs of latitude and longitude that the light source can travel on are displayed during the movement.
June 2004 DelphMap™ User's Manual In this dialog box you also can specify one of four file formats to be used for any snapshots of three-dimensional imagery that you make: BMP (the default), TIF, TGA, or PCX. FIGURE 46.
June 2004 DelphMap™ User's Manual Chapter 6 Displaying Image Profiles Overview Normally, you view your imagery in DelphMap from the top down (“bird’s-eye” view). DelphMap can also display your imagery in a side view. This is called a Display Profile. The view takes the form of a single line showing the height and breadth of whatever area you are profiling.
June 2004 DelphMap™ User's Manual If your profile is just that of a bathy layer, you get a profile showing just depth. The layer’s name appears in the upper right corner of the displayed profile. Figure 48 shows an example of this. If you move your pointer from the imagery in the Main Display window to the Display Profile window, the system might draw a line in your imagery without an apparent termination point (i.e., the end of the line lacks a green box).
June 2004 DelphMap™ User's Manual • If your profile is a mix of sidescan and bathy layers, the displayed profile has panels for both amplitude (for sidescan layers) and depth (for bathy layers). Figure 49 shows an example of that kind of graph. In the example, notice that the amplitude signal is absent beyond 50 meters into the profile of the sidescan data, but that the bathy profile continues for the remainder of the profile.
June 2004 DelphMap™ User's Manual FIGURE 49. Amplitude and depth reported in a display profile Changing the Look of Your Display Profile After you have generated your profile, you can put your pointer in the Display Profile window to perform other actions on the profile.

The profile line transverses the length of the imagery from one border of the main display to its opposite border.
June 2004 DelphMap™ User's Manual Changing Profile Setup Parameters In addition to the icons noted in Table 3, DelphMap provides a dialog box for changing other facets of your display profile. This gives you a way to further customize your display profile. To examine and change the current profile setup values 1. In the Display Profile window, click the Profile Setup icon (right). The system displays the Profile Setup dialog box (Figure 50).

June 2004 DelphMap™ User's Manual Changing Field of View and Point of Focus A slider bar at the bottom of the Display Profile window can be manipulated to change the profile’s apparent field of view and its apparent point of focus into the profile. The Field of View slider bar has two white movable handles. Initially these handles are at the far ends of the slider bar (as shown in Figure 47, for example). Initially the bar is all green, indicating that the bar (and thus the graph) is fully expanded.
June 2004 DelphMap™ User's Manual 2. Stop dragging when you reach a desired field of view. Initially, therefore, you will be able to drag handles only toward the center of the slider bar; thereafter, you can move handles left or right. The red part of the slider bar indicates a part of the profile that is no longer in your field of view in the Display Profile window. As you move the slider bar the horizontal scale of the profile line changes to reflect the shifted, apparent field of view.

June 2004 DelphMap™ User's Manual Chapter 7 Printing and Comparing DelphMap imagery can be printed. You can also use DelphMap to compare two files and reveal the differences to you. Printing You can print the image displayed in DelphMap’s main display window. You can also preview the image before printing it, and you can adjust the scale before printing. Prior to printing, you should always set up your printer/plotter first and decide what paper size you are going to use.

June 2004 DelphMap™ User's Manual Chapter 8 TIFF and GeoTIFF Differences A Peek at TIFF and GeoTIFF Differences Many raster file formats can be displayed as images on a PC. Prominent among these formats is the TIFF format. A TIFF file can be read by almost all graphical “paint-style” programs that commonly run on the Windows operating systems. (TIFF files, usually identified by the file extension TIF, also can be imported into other, major applications such as Microsoft Word.

Geo-referenced files can do this if those files make all their geo-referenced information available in a separate header file. (In fact, if the header file contains geo-referencing, the file is then a special kind of header file called a world file.) In the case of DelphMap, the world file has an extension of TFW and is created whenever a TIFF or GeoTIFF file is exported from DelphMap.

June 2004 DelphMap™ User's Manual CHAPTER 9 Troubleshooting Problems Frequently Asked Questions…and Answers Some problems go away by using simple workarounds. Here are some workarounds to some common problems. Question: What do I do if I encounter the following message? The ordinal 6880 could not be found in the dynamic link library MFC42.DLL Answer: MFC42.DLL problem is indicated. That message can be generated when serialsrv.exe is started by double-clicking on it in Windows explorer.
June 2004 DelphMap™ User's Manual However, if DelphMap is not running, then the old version of MFC42.DLL will be loaded because serialsrv.exe is located in the \TEIdlls folder and does not have access to the new MFC42.DLL. This results in the error message noted earlier. None of these problems occur with Windows 2000 because all required system DLLs are at a high enough revision level, and no system DLLs are loaded by the installation.
