What is an OnDemand Topo?
OnDemand Topos are USGS topographic maps generated on demand (at no cost) using the topoBuilder application and the best available data from The National Map. The ability to customize your map and center it wherever you choose is exclusive to topoBuilder.
OnDemand Topo map extents do not need to align with the traditional grids utilized by US Topos and other USGS topographic maps. Once a map has been built and requested through topoBuilder, it will be digitally delivered by email. Maps are often delivered within 24 hours but can take up to 5 business days.

Why is the orthoimage (air photo) layer not available for some US Topo maps and OnDemand Topo maps?
In the lower 48 States, orthoimages (rectified air photographs) for US Topo maps and OnDemand Topo maps comes from the National Agriculture Imagery Program (NAIP) . There are areas over some military installations where NAIP imagery is not available. In these locations, the OnDemand Topo maps will either not include imagery or contain partial imagery. US Topo maps are only produced for areas that...
How do USGS OnDemand Topo maps differ from US Topo maps?
USGS OnDemand Topo maps and USGS US Topo maps are built using similar datasets but can look different depending on what areas or options the user selects. OnDemand Topos--created using the topoBuilder application --offer customizations such as custom extents, a variety of scales, contour smoothing, and user-selected data layers. They include U.S. Territory coverage that is not available on US...
How current are US Topo maps?
US Topo maps are updated on a three-year production cycle (maps covering one third of the country are updated each year). The US Topo production schedule follows the U.S. Department of Agriculture's National Agricultural Imagery Program (NAIP) collection schedule. This does not include US Topos for Alaska, which are on a different schedule . The linework features shown on the maps are generated...
How do USDA Forest Service maps differ from USGS topographic maps?
USDA Forest Service Visitor Maps are at a smaller scale (they show a larger area but less detail) than standard 7.5-minute (1:24,000-scale) USGS topographic maps. Unlike USGS topographic maps, Forest Service Visitor maps typically do not show elevation contours. U.S. Forest Service Visitor Maps include recreational information about camping, fishing, biking, and other outdoor activities. They...
Are US Topo products available for Alaska?
Yes, US Topo products are available for all of Alaska. Publication of 1:25,000-scale US Topo maps in Alaska began in 2013. The production schedule is determined by availability of IFSAR elevation data and SPOT imagery provided by the Alaska Statewide Digital Mapping Initiative . To see an index map of publication dates for US Topos in Alaska, go to the National Map Downloader . Put a checkmark...
