Description (boydsmaps version)

This map is a locally-cached version of the USGS National Map Topo as of January 1, 2023. It provides a contemporary companion to the USGS 24k Legacy and 62k Historic topos and loads much faster than the version on USGS servers. Note that the resolution of this map was doubled on 4/6/2025 with full level 16 coverage. It now provides the same level of detail as the remotely-hosted version from USGS servers.

The map includes full coverage of Connecticut, Delaware, Maine, Maryland, Massachussets, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia and West Virginia with partial coverage of Kentucky, Tennessee, Indiana and Michigan. While it would be nice to expand the coverage of this map someday, there are no plans to do that in the foreseeable future.

Original USGS Description

USGS Topo combines the most current data in The National Map (TNM), and other public-domain data, into a multi-scale topographic reference map. Data themes included are Boundaries, Geographic Names, Transportation, Contours, Hydrography, Land Cover, Shaded Relief, and Bathymetry. This service is designed to provide a seamless view of TNM data in a geographic information system (GIS) accessible format.
