The USGS is planning to discontinue service to the previous versions of the National Map viewer application.

The USGS National Geospatial Program (NGP) will be decommissioning its legacy National Map viewer application on September 29 2017. This is part of a continuing effort to move towards data visualization frameworks that support the new HTML5 advances in web environments, improve mobile access, and add GIS capabilities while minimizing the government's role in maintaining custom viewer code.

The NGP technical staff recommends that users transition to using the National Map Advanced Viewer application. Users have been directed towards this new viewer application through the launch web page since April 2017.

The primary purpose of the new viewer is to provide our users with a means of visualizing and working with our data over the web. Note that the USGS already has a separate application focused on data download and that download functionality is not part of the replacement application at this time.

The new viewer application was built using the ArcGIS Online Web AppBuilder. Featured “Widgets” are:

  • Base Map Gallery
  • Layer List
  • Legend
  • Add Data
  • Share
  • Query
  • Measurement
  • Elevation Profile
  • Spot Elevation
  • Print
  • Draw
  • Select

For assistance, refer to the Help documentation. Additional information is found at other visualization capabilities.  If there are features that you used in the legacy National Map viewer that are not yet in the new viewer, please contact The National Map Help Desk to communicate those needs to the appropriate technical representative.
