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.
