What do you need to know about the USGS Topo?
View Footprint In: ArcGIS Online Map Viewer. Service Description: USGS Topo is a topographic tile cache base map service that combines the most current data (Boundaries, Geographic Names, Transportation, Elevation, Hydrography, Land Cover, and other themes) that make up The National Map.
What was the previous version of the USGS base map?
The previous version of the USGS Topo base map was only cached to 1:18,000 scale (level 16 in Google Maps tile levels) and was intended to be used with a slower dynamic service at scales when needing to support zoom below 1:18,000. Now that the new service is available at a larger scale, the older partner dynamic service will be retired.
