Base Maps
A base map is a geographic layer providing background information and spatial reference for other layers displayed on the map.
TENGRAPH Web has 7 base maps including aerial, topographic and geology imagery.
To begin make sure the Layers panel is active by clicking on the Layers Tab.
The Base maps folder is located near the bottom of the Layers panel. Click on one check box from the Map Layers List to make the corresponding base map visible.
Adjust the map display by moving the transparency slider left, allowing other layers turned on to be seen.
The table below demonstrates and describes in more detail the base maps available.
