A basemap provides a background, or visual context, for the data in a map. For example, a basemap showing streets can provide context for your address data. ArcGIS includes several different types of basemaps for you to use in Esri Maps for MicroStrategy, including aerial imagery, terrain, streets, and topographic data. The default basemap displayed in the map is determined by your administrator. You can change the basemap at any time to one of the other maps provided.
