7.5-Minute OnDemand Topo Cartographic Specifications

This page and associated links define the U.S. Geological Survey (USGS) 7.5-Minute OnDemand Topo cartographic specifications including feature symbology and annotation. The specifications are organized by data sets and themes listed below.

Additional Information

OnDemand Topo maps are intended to serve conventional map users by providing geographic information system (GIS) information in symbolized form in the customary topographic map layout. The maps are not intended for advanced GIS analysis applications. These products are built on standard coordinate systems and include full U.S. National Grid (USNG) lines, making OnDemand Topo maps particularly useful for emergency first-response operations. These maps are also used by traditional topographic map users, such as resource managers, planners, and recreational users who continue to have a need for the symbolized feature data contained.



The National Geospatial Program (NGP) of the USGS maintains standards for The National Map (TNM;, including map standards for OnDemand Topo products, US Topo prod­ucts, and Historical Topographic Map Collection products.
