The Lucity Web map allows administrators set up multiple base maps that users can then switch between. The map services that are used as base maps are specified in the Administration Tool under GIS > Map services, by checking the Base Map? box.
Note: Base maps must be either a tiled map service, an image service, or a Bing map.
A Base Map button is available on the Web Map toolbar. Click this button, and a drop-down list of all available base maps appears, displaying a thumbnail of each base map.
Thumbnails are automatically provided when using Bing maps. If an agency is using locally created map services, the thumbnails must be set up by the administrator.
