USGS DRG topographic maps:

The 7.5-minute maps (1:24.000/1:25.000) are the best maps for outdoor activities in the USA. Although some of the maps are quite old, they contain many small pathes and 4WD tracks that are missing in new USTopos, Google, Bing and OSM maps.

New US Topo Maps:

US Topo maps are a graphic synthesis of The National Map data files and are produced in the familiar 7.5-minute by 7.5- minute geographic format. Current US Topo map layers include an orthoimage base, transportation, geographic names, topographic contours, boundaries, hydrography and woodlands. Also included are the Public Land Survey System (PLSS) and the United States National Grid.

NAIP Orthoimagery:

Seamless coverage of contiguous US with 1m/pixel resolution

HRO aerial imagery:

High resolution arial photos covering US urban areas & borders (up to 10cm/pixel)

Use this navigation app for outdoor activities like hiking, biking, camping, climbing, riding, skiing, canoeing, hunting, snowmobile tours, offroad 4WD tours or search&rescue (SAR).
