Legend and Map Display Panel
- The map legends are grouped in tabs by category.
- Each layer on the map is listed by name with its map symbol.
- Certain layers can be turned on or off one at a time by checking or unchecking the boxes in the list.
- Some layers are not displayed on the map at all scales. When the map is zoomed out those layers are not visible. In this case the checkbox for that layer is disabled in the legend.
- Similarly, the Aerial Image can be displayed using the button below the legend. The imagery can not be displayed when the map is zoomed out at larger scales, so the button is disabled until the map is zoomed in.
- The option to manually toggle the Base Map layers is typically limited to select layers (if any), such as the map labels.
