Digital Editions of USGS Topo Quad Maps Available Online

Posted on: |

If you need to obtain digital topo maps, USGS has been developing a collection of current and older topos that are free to download. The April 9 release of new maps covering Texas and New York continues the US Topo revisions, updates and product improvement.

These maps complement the paper editions in the UB Map Collection and provide access to earlier editions of maps for the states (currently, the UB Map Collection holds only the latest editions of state topo quad maps, except for NY and PA; these two states we have all editions).

The newest sets of US Topo maps cover the states of Texas and New York. The 4,309 quadrangles for Texas and 972 quads covering New York replace the existing US Topo maps for those states, and will be added to the USGS Historical Topographic Map Collection. All of these maps are available for free download from The National Map and the USGS Map Locator & Downloader website.

Last September, the USGS marked the important milestone of completing the initial round of US Topo map production for the 48 contiguous states. The agency is continuing to improve the US Topo map product, moving into the next round of national map revisions. Hawaii is currently in production and Alaska production will start later this year.

“The US Topo program is a dynamic product and the new maps for Texas and New York demonstrate our commitment to a very aggressive three year revision cycle while at the same time adding new content,” said Mike Cooley, the US Topo Project Manager. “I encourage you to take a look at these maps and drop us a comment on how we are doing via our drop box, as your input is important to us.”
