GM_LoadTerraServerLayer (DEPRECATED) |
NOTE: This function is now DEPRECATED. Please use GM_LoadOnlineLayer instead.
Loads data from the TerraServer, including DRG, DOQ, and urban area imagery. If either the aThemeName or aLatLonRect values are NULL, a dialog will be displayed asking the user which theme and bounds to load.
Valid theme names are as follows:
- "DRG" - USGS DRG scanned topographic maps
- "DOQ" - USGS DOQ grayscale aerial imagery with 1 meter resolution
- "UrbanArea" - NIMA/USGS high resolution color imagery
The layer handle returned in aLayer must be freed with a call to GM_CloseLayer when the caller is done using it.
