You will see a menu on the left hand side, with a list of all of the basemaps you have access to.
Filter by Cadence
You can filter these basemaps based on cadence (i.e. daily, weekly, monthly, quarterly). If a basemap does not fall into a regular cadence, it will be listed under the "Other" filter.
Search by Location
You can search for a basemap by typing in a location into the search bar at the top of the screen.
