When will US Topos be available for the whole country, or for an area specific to my need?
The production of US Topos follows the U.S. Department of Agriculture National Agricultural Imagery Program (NAIP). USGS intends to refresh the map series for the conterminous United States once every 3 years. The first 3-year production cycle was 2010-2011-2012 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. will be completed in the fall of 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, but will likely take 6-8 years to complete see ( Statewide Digital Mapping ). No schedules have yet been set for the Pacific Territories.
