New urls for National Map services

The National Map – Applications

The National Map’s applications are now hosted at apps.nationalmap.gov. To help facilitate this transition, traffic to viewer.nationalmap.gov is automatically redirecting to the new application URLs. We encourage you to update any bookmarks you have for viewer.nationalmap.gov URLs so you can access these applications without relying on the redirects now in place. Please contact the TNM Help Desk at tnm_help@usgs.gov if you have any questions.
