Can I import a US Topo map into my Geographic Information System (GIS)?

Modern USGS topographic maps are derived from GIS data sets and are distributed as a digital Portable Document Format (PDF) for the benefit of non-specialist users. USGS topographic maps are considered the output of, rather than the input to, GIS.

Many Geographic Information System (GIS) software cannot read or import a PDF file. It is not recommended to use USGS topographic maps in a GIS environment beyond reference or base map purposes.

Many common GIS software support GeoTIFF formats. All USGS topographic maps available from TopoView are free to download in a high-resolution GeoTIFF format and can be brought into GIS for reference purposes. All other source data shown on current USGS topographic maps is also available in GIS-usable vector format from The National Map Download Application.
