USGS Topographic Maps

USGS topo maps indicate surface terrain data such as elevations, road patterns and streams. The standard topos do not show subsurface geologic data or stream pattern information. The quads or 1:24,000 scale maps offer the largest detail and are updated more frequently than other scales.

HAWAII
Topographic maps for the eight major islands (Oahu, Hawaii, Maui, Kauai, Molokai, Lanai, Niihau and Kahoolawe) are available at a 1:24,000 scale. Contour intervals are 40 feet for the larger islands and 20 meters for the smaller islands. Also available are the 1:50,000 metric series. The 1:62,500 scale maps are available only for the islands of Oahu, Maui and Molokai. See index for specific islands. Topo maps for the Northwest Hawaiian Islands (e.g., Necker, Laysan, Midway), primarily bird and marine life sanctuaries, are not available.
Pacific Islands
USGS maps for the Pacific Islands include American Samoa, Guam, Tinian, Rota, Saipan, Kosrae, and Chuk (Truk).
Other States
Overall state maps at a scale of 1:500,000 are available for most continental US states. West Coast states are also available at a 1:250,000 scale.
