Where can I get an index of US Topo maps?

For information about traditional paper indexes, see this FAQ. Be aware that paper indexes are basically historic documents; USGS is not printing new versions for current products.

For a visual index of standard cells and associated products, see the search and download applications for US Topo and Historical Topographic Map Collection (HTMC).

For digital indexes that can be used in GIS:

  • Standard cells: Digital cell indexes in Shapefile and FGDB formats can be downloaded here.  These are indexes of standard cells, not published maps. They contain the cells of the primary topographic map series (historical and current) in the 50 states, Puerto Rico and Virgin Islands, Pacific Territories, and Antarctica, and well as the 3.75-minute cells that were used for Digital Orthophoto Quarter-Quad (DOQQ) product in the 1990s.
  • Published maps: A database dump in CSV format can be downloaded for standard topographic maps in the US Topo series and the Historical Topographic Map Collection. This file can be joined to the cell index above to create spatial indexes of published topographic maps. This file is updated nightly; about 75 US Topo maps are added each work day. For Web programmers, a more powerful way to get product information is through the ScienceBase API.
