Downloading USGS Topo Maps from the National Map Viewer

Downloading USGS Topo Maps from the National Map Viewer

This short tutorial will detail how to download current topographic maps for an area of interest from the National Map Viewer. This is a platform where the most recent topographic products can be downloaded free of charge.

  1. Download the most recent USGS GeoPDFs for an area of interest at: http://viewer.nationalmap.gov/viewer/
    1. Zoom into your area of interest (here we will explore Assateague Island National Seashore as the example).
    2. In the menu on the left-hand side of the window, click the + next to the US Topo Availability heading to expand this option, and also check the corresponding box to turn on all of the associated layer (see below).
      1. If you click the + next to Index of Available Maps, the legend will describe what color is associated with the publication date of the topo maps for a certain area.

  1. As you can see, the majority of Assateague has Topo maps published in 2014, although at the southern end of the island features maps published in 2013.

  1. To download a map, simply click inside one of the quadrangles. This will open a pop-up menu that provides details about that specific quadrangle, such as the counties covered, the primary state, the date on which the map was created and a link to download the GeoPDF.
    1. To download the GeoPDF, click on the link that has been provided (see below for more details).

  1. Repeat this process for each of the quadrangles within your area of interest (AOI).

These workflows have developed and tested by the Environmental Data Center at the University of Rhode Island with the support of a competitive grant (cooperative agreement number P09AC00212; task agreement number P13AC00875) from the National Park Service in partnership with the North Atlantic Coast Cooperative Ecosystems Studies Unit. It is part of a larger document available for download on the IRMA Portal.​
