Map Background
To manage MAGNET Field-predefined and custom map backgrounds from the Web Map Services.
This dialog opens from the Backgrounds tab of the Map Properties dialog by clicking
in the Background Map field.
Choose the type of Map background to use: either Predefined, Custom WMS, or none.
- Check the Predefined box to display predefined map backgrounds. Currently there are three predefined map backgrounds:
- Bing™ Hybrid;
- Bing™ Terrain;
- OpenStreetMap (© OSM).
The coordinate system of the background images is a corresponding UTM projection.
- Check the Custom WMS box to display raster background images downloaded from the Web Map Services (WMS).
- The raster background images are presented as a logical tree. Expand the tree nodes to see the names of the separate image layers (states, rivers, cities, etc.). You can select any or all layers from the list for loading to the application.
- Clicking the Edit button opens the WMS Records dialog, where you can add a new WMS record, edit or delete existing WMS records or change the displaying order of the images from the existing WMS records.
- The fields
display upper left corner and lower right corner boundaries coordinates for the highlighted WMS background image.
- Clear both check boxes to use no map backgrounds.
Click the
button to open the dialog's menu with additional commands.
- WMS Info - Web Map Services can support grid projection(s). To see a list of supported projections, select this command and open the WMS Projections dialog. If the Web Map Service supports projection and a user selected this supported projection as the current job's projection (in the Coordinate System dialog) the WMS background image will be displayed in the supported projection. For all other cases the WMS background image will be displayed in the corresponding UTM projection.
- Clear Cache - select this command to delete all downloaded WMS images in the application’s cache memory. Click Yes to confirm deletion or click No to cancel. If the corresponding WMS record remains in the dialog but all map images are deleted from the application’s cache, the application will start downloading the images from the WMS record again.
Click
to save the changes to map background settings and return to the Backgrounds tab of the Map Properties dialog. Click
