Chapter A How To Localization in MAGNET Field When you need to obtain points' coordinates in different Grid coordinate systems or a Datum predefined or created in MAGNET Field, simply select a desired coordinate system. MAGNET Field will use its own mathematical algorithms to transform coordinates from the current system to the selected one. For examle, a MAGNET Field job is configured for RTK survey in a certain grid coordinate system, for example, SPC83-Texas (Central).
How To · · · · · · · Localization with Stereographic Projection on any Datum Localization with any Predefined or Created Projection One-point Localization Two-point Localization Three-point Localization Performing Localization Importing Localization Data to Other Job Basic Concept of Localization Localization in MAGNET Field is a calculation of transformation parameters between WGS84 and a ground coordinate system.
Localization in MAGNET Field part in both localizations, MAGNET Field will calculate and use seven parameters for transformation of all job points: In the horizontal plane (find out the plot here) - offset vector (DX, DY) between the origins of coordinate systems, rotation angle between these coordinate systems, and scale factor. In the vertical plane - one shift (HO), and two slopes (Hx, Hy). If a geoid is set in the job, MAGNET Field will use this geoid for calculating orthometric elevations.
How To tance between the local points is less than 5 kilometers, you can use the simplest localization. To do this type of localization, set Projection to None in the Coordinate System dialog before entering localization point(s). In this case MAGNET Field will ONLY use an oblique stereographic map projection on WGS-84 as an intermediate step. The Localization dialog will have only WGS84->Local type in the Type field.
Localization in MAGNET Field To calculate the localization parameters between two coordinate systems is a more rigorous method than using the stereographic projection for an unknown local projection. This way enables you to increase the distance between localization points (up to some hundred of kilometers depending on the type of the projection) without loss in transformation precision.
How To Total Station network) and point "C-2_WGS-84" (for GPS network). Plot C shows that, if both the coordinate systems have non-zero rotation angle, the accuracy of transformation with only one localization point can be very poor.
Localization in MAGNET Field Also, the horizontal (rH) residuals for these localization points are calculated. Three points of localization are enough to calculate all transformation parameters in the vertical plane. The vertical (rV) residuals for these points are not calculated and equal zero (see our example here). Performing Localization Learn localization on a practical example.
How To than 80 cm for plane coordinates and more than 1 meter for elevation for this network. The user decides to use localization in MAGNET Field. Before Rover Measurements To preform localization, you need two sets of the coordinates. The first is a set of the benchmark coordinates in the "31 UTM IGN.” This set will be used as a set of GROUND coordinates. The user has this data and only needs to import this set to a MAGNET Field job.
Localization in MAGNET Field The error of adjusted coordinates does not exceed 12 mm in plane and 16 mm in height, which meet the specified accuracy of transformed coordinates (see the results here). These adjusted coordinates can be used as: · Coordinates of the base stations to work in RTK mode · Set of coordinates in WGS84 for localization The user exports these coordinates (from the MAGNET Tools job) in text file format and selects "dd mm ss.
How To 1. Click the Exchange icon and then From File . 2. In the From File screen, select the Topcon Text Custom file format and click Next to continue importing. 3. Navigate to the desired file in the From Text screen and click . 4. Select the comma delimiter for this file (see the file created in MAGNET Tools here) in the Text File Format and click Next. 5. Select the WGS84 datum and WGS84(Lat/Lon/Ell ht) coordinate type of the imported file in the Coordinate System screen and click Next. 6.
Localization in MAGNET Field 1. To import this file into the MAGNET Field job, in the From File, select the "NEZ(*.csv)" format. 2. Select the GROUND coordinate type in the Coordinate System dialog to import the set of these coordinates. 3. After the import finishes successfully, the Point screen displays the coordinates of both sets. Setting the Desired Projection You need to set the projection, which will be used in localization. 1. Click the Configure icon and then the Coordinate System icon . 2.
How To Add, to add the corresponding file. See an example of adding the appropriate geoid file here. After Rover Measurements Measure all rover points from the corresponding base stations and after completing all measurements, perform the localization procedure to transform rover points from the WGS84 coordinate system to the Ground coordinate system. In the given case the ground coordinate system matches the "31 UTM IGN" projection. Creating Localization Points 1. Click Setup and then Localization . 2.
Localization in MAGNET Field In the same example, ONLY for TEST, select the WGS84>Ground type of localization. MAGNET Field will use the stereographic projection on WGS84. This time the error of transformation will be more than 1.9 meters (in horizontal localization) for such distances between the localization points. Importing Localization Data to Another Job If you want to import localization data from one job to another job, you can activate the automatic import procedure of localization data to a job.
How To Grid to Ground Transformation MAGNET Field supports two methods for setting the relation between Grid and Ground coordinate systems. One method performs scaling and rotation relative to some point of the job. The other method performs scaling and rotation relative to the origin of the Grid coordinate system. To get started with transformation: 1. Click the Configure icon and then the Coordinate System icon . 2.
Grid to Ground Transformation Parameters of transformation from the Grid to Ground coordinates can be used in the GPS stake of road points. For example, to stake a point at the distance of 100 meters from some point, you have to create a ground coordinate system, which will work as a base coordinate system in GPS stake calculation. To do this, select the corresponding Grid and enter the average height of a desired portion of the road.
How To Example of Using "Origin Pt" The current MAGNET Field job contains two sets of measured points: · One network of points measured by a GR-3 receiver from a reference station in Grid coordinate system, for example, SPC83 -Ohio(North). · Another network of points measured by a Topcon Total Station (GTS-220) in the Ground coordinate system with the arbitrary choice of zero BS azimuth. These networks have: · A common point - the point CP2 of the GPS network and point CP2_TS of the TS network.
Grid to Ground Transformation 2. Check the Use Grid / Ground box to use this transforma- 3. 4. 5. 6. tion, and press to open the Grid/Ground Parameters screen. Select "Origin Pt" in the Parameters field to activate this method. Select the origin point in the Grid coordinate system (CP2 point) from the list. Remove the coordinates of the selected point in the fields Northing and Easting, which MAGNET Field automatically writes in the Grid coordinate system.
How To MAGNET Field calculates the corresponding azimuth when you select the start and end points of the line. 2. Click in the Azimuth Rotation field. The Compute Rotation screen allows the calculation of Grid and Ground azimuth to obtain the rotation angle between two coordinate systems (see Grid to Ground Transformation Without Rotation). 3. Click the Compute button in the Ground line.
Grid to Ground Transformation then, in the Grid/Ground Parameters screen, you can select "Scale Factor" or "Avg Job Ht". This method calculates plane ground coordinates by scaling, offsetting, and rotating grid coordinates. Find a graphic explanation of transformation only by scaling here, only by rotating here, and only by shifting here. To find a relation between Grid and Ground coordinate systems: 1.
