US Topo FAQs - 32 Found
US Topo production follows the U.S. Department of Agriculture National Agricultural Imagery Program (NAIP). USGS intends to refresh the map series for the conterminous United States every 3 years. The first 3-year production cycle was 2010-11-12 and achieved almost full coverage of the conterminous 48 states (except for a few restricted military areas). The second 3-year cycle for the conterminous U.S. was completed in September 2015.
Hawaii, Puerto Rico, and Virgin Islands were completed in 2013 and will be part of the regular 3-year cycle from now on. Alaska was started in 2013. The schedule for Alaska is driven by collection of new image and elevation data by the Alaska Statewide Digital Mapping Initiative. Full coverage of Alaska is projected for 2018. US areas of interest in the Pacific are tentatively scheduled for 2017.
