Showing/Hiding Features on the Map Screen
•Tap Menu>Layers...
• Enable or clear the check box placed before each layer
name to respectively show or hide the layer on the map
screen. Showing a layer means showing all the features
logged in that layer.
Adding Existing
Layers to a Map
Job
• Open the job in which to add layers, using
Menu>Job>Open....
•Tap Menu>Layers. A new window opens listing all the
layers currently attached to the map.
• Tap on the Add... button
• Tap in the Type field and select “*.shp”, “*.csv” or
“*.mif”. MobileMapper Field browses all the folders in
search of all the layers of that type stored in the receiver.
• Select the file you want to add to the job as a layer. This
opens a new window showing the viewing options,
attributes and scale defined for this file.
•Tap OK. This takes you back to the screen showing all the
layers attached to the job, including the new layer you’ve
just selected.
•Tap OK to return to the map screen. The new layer is now
available for feature logging.
NOTE 1: Adding an existing layer to a new job as the first
layer in this job will cause the layer’s coordinate system to
definitively become the coordinate system attached to the
new job.
NOTE 2: Attempting to add a layer that is incompatible
with the coordinate system used by the job will cause a
warning message to be displayed. You can however
override the message and ask MobileMapper Field to add
this layer. In this case, be aware that the layer will contain
positional information based on different coordinate
systems. It will be your responsibility to identify which
coordinate system is used in the description of each
feature.
Adding
Background Maps
Background maps are raster files that can be displayed on the
map screen to help you better locate the different features
found in the working area.
In order to be used in MobileMapper Field, a background map
must be in image format (BMP, GIF, GeoTIFF, JPG or JP2) and
properly georeferenced.
