US Topo maps are intended to serve map users who are not GIS specialists. The priority design objectives were to create a traditional topographic map as a digital document that could be displayed on a typical computer without specialized software and printed at map scale without specialized software or expertise. We believe PDF is the only format in common use that satisfies these requirements. PDF is also the only commonly used format that can carry raster data, vector data, and formatted text annotation.
All dates of USGS topographic maps (both Historical topographic maps and US Topo maps) can also be freely downloaded in GeoTIFF, JPG, and KMZ formats using TopoView.

Can I get a bulk order of USGS topographic maps in PDF format for a state or the entire country?
Bulk delivery is available for US Topo maps (produced 2009-present) and the Historical Topographic Map Collection (produced 1884-2006). Only current US Topo maps (not superseded maps) are available for bulk distribution (use topoView to download individual superseded maps). Bulk delivery options are currently only available for maps in GeoPDF file format. Options for bulk delivery: 1. Batch...
What is a GeoPDF®?
A GeoPDF is a georeferenced PDF file, meaning that it is a Portable Document Format (PDF) file with added information that relates the image to coordinates on a map. GeoPDF files can be used as plain PDF files but have the added capability of some limited mapping functions (turn any map layers on and off, obtain XY coordinates for a location, measure length, and more).The USGS currently produces...
What is GeoMark and do USGS topographic maps have it?
Almost all historical topographic maps and all US Topo maps produced before June of 2017 were georeferenced using software from the company TerraGo. Those maps are all GeoMark enabled. GeoMark is TerraGo's geospatial data extension to PDF markup. GeoMark allows notes and geometric objects (lines, polygons, etc.) to be added to a GeoPDF and allows these objects to be exported to GIS files. Users of...
What does "georeferenced" mean?
Georeferencing means that the internal coordinate system of a digital map or aerial photo can be related to a ground system of geographic coordinates. A georeferenced digital map or image has been tied to a known Earth coordinate system, so users can determine where every point on the map or aerial photo is located on the Earth's surface. The relevant coordinate transforms are typically stored...
How do I find, download, or order topographic maps?
The U.S. Geological Survey (USGS) has been the primary civilian mapping agency of the United States since 1879. USGS topographic maps have been published at many scales, but 1:24,000 (also referred to as a 7.5-minute quadrangle) has been the standard topographic map scale since 1947. For Alaska the standard scale is 1:25,000. All dates and all scales of our topographic maps can be freely...
How do US Topo maps differ from historical USGS topographic maps?
Historically, USGS topographic maps were made using data from primary sources including direct field observations. Those maps were compiled, drawn, and edited by hand. By today's standards, those traditional methods are very expensive and time-consuming, and the USGS no longer has funding to make maps that way. A new USGS topographic map series was launched in 2009 and branded "US Topo." Though...
Can I import a US Topo map into my Geographic Information System (GIS)?
Most Geographic Information System (GIS) vendors do not yet provide geospatial PDF import capabilities. US Topo maps are derived from GIS data sets and are formatted as PDF for the benefit of non-specialist users. We consider the product to be primarily an output of—rather than an input to—GIS. However, we recognize the demand for symbolized maps in GIS, and we are working on a companion product...
How can I find the source and vintage of each US Topo data layer?
US Topo maps have a credit legend in the lower left-hand corner of the map collar. This includes a short summary of data sources and data currency. More detailed source information is in an XML metadata file attached to each GeoPDF file. This file contains series-level, quad-level, and layer-level metadata, but US Topo does not preserve or track feature-level metadata. Open the GeoPDF map file in...
