By using Esri maps, you can visualize and analyze chart items in a geospatial context, according to the location data that the items contain. Different maps are available, depending on the ArcGIS servers that you are connected to.
There are two types of map: base maps and dynamic maps. After you load your first base map, you might find that other base maps become unavailable. Any other base maps that you load must use the same coordinate system as the first.
