I found an error on a map. How can I report it and when will you fix it?

There are different answers to this question for different products. In all cases, we must know what product you are addressing. Please read the following guidelines and email error reports to tnm_help@usgs.gov:

US Topo maps (topographic maps published 2009-present)

Please include the following information:

  1. The map title, state, and date (from the title block in the lower right corner).
  2. Description of the error.
  3. Location of the error.

For location, coordinates are preferred in latitude/longitude, UTM, or USNG. Otherwise include a detailed description of the feature and its location so someone not familiar with the area can find it on the map. A screenshot image would be most helpful.

The US Topo project does not edit data and performs only limited data verification. Data sources include both government and non-government organizations. If errors are determined to be a source-data issue, they will be passed to the data owner. Unless there is a serious error, US Topo maps will not be reissued. The corrected data will be included when the map is remade in the regular 3-year cycle

Historical Topographic Maps (topographic maps published before 2007)

USGS maps in the Historical Topographic Map Collection are historical documents and will not be revised or corrected. Historical USGS maps are often used as a base map for commercial map products that make modifications or add enhancements and put a current date on the map. The USGS has no control over those products.

Web Maps

Confirm that the application is owned by USGS. Send us the URL of the application and coordinates of the feature in question. If you don't know how to extract coordinates, send a screen-grab image and a description of its location, such as city and state, or direction and distance from a town or highway intersection.

GIS data

Confirm that the data are from the USGS. Send us the dataset title and date from the metadata file or the download URL. Please provide the coordinates of the feature in question and any relevant feature attribute information. Screenshot images are helpful.

Why are some of the historical topographic maps yellowed and why do some have extra stamps or marks?

The goals of the Historical Topographic Map Collection (HTMC) project are to find, catalog, and georeference all USGS topographic quadrangle maps published prior to 2007. The overall purpose is to preserve the map archive for scientists, historians, and the public. Library copies of maps (many of which have library stamps) were therefore scanned "...

There are multiple copies of the same map in your Historical Topographic Map Collection that all have the same date. Is there a difference between those maps?

Yes, these are different maps that typically resulted from revisions and reprints. The differences are often minor. The date used to identify a map can be found in the lower right corner. If there are multiple editions with the same compilation date, look for additional dates in the lower right portion of the map collar that might differentiate...

Your map has road/address errors and people can't find my house

This issue is usually about maps on GPS devices, smart phone applications, or commercial online maps. The USGS does not provide road or address information for those products, almost all of which use road data from commercial sources. The USGS has no relationship with those companies. The USGS mission does not include the collection and...

Why do all of the coordinates (latitude and longitude) in the Geographic Names Information System seem incorrect?

Coordinates that seem to be incorrect in the Geographic Names Information System might just be projected on a different datum from the datum used on your map or your positioning system (GPS). Most USGS maps published approximately 1940-1995 are projected on the North American Datum of 1927 (NAD27) . Later maps are projected on the North American...

How do I report an error in the Geographic Names Information System Database?

Please report possible errors to the Geographic Names Information System Manager at BGNEXEC@usgs.gov . The Names data experts will investigate and validate the data, enter appropriate corrections where needed, and advise you of the results.

US Topo

US Topo is the next generation of topographic maps from the U.S. Geological Survey (USGS). Arranged in the familiar 7.5-minute quadrangle format, digital US Topo maps are designed to look and feel (and perform) like the traditional paper topographic maps for which the USGS is so well known. In contrast to paper-based maps, US Topo maps provide modern technical advantages

Cartographers in the Field

This Depression-era oil painting was created by USGS field man Hal Shelton in 1940. The painting depicts mapping techniques used in the early days of cartography, including an alidade and stadia rod for determining distances and elevations and a plane-table for sketching contour lines. A USGS benchmark is visible near the top. The straight white lines represent survey
