US Topo FAQs - 28 Found
Send email to firstname.lastname@example.org. Please include the following information:
1) The map title, State, and date (from the lower right corner of the map face).
2) Description of the error.
3) Location of the error.
For location, geographic coordinates are preferred. These can be read directly from the screen if you use the TerraGo Toolbar and GeoPDF extensions. They can also be read from the grid annotation as on a traditional paper map. Otherwise include a detailed description of the feature and its location so someone not familiar with the area can find it on the US Topo.
The US Topo project does not edit data, and performs only limited data verification. The project accepts data from authoritative sources and repackages these data into a standard topographic map format. Error reports will be evaluated, and if determined to be a source-data issue, will be passed to the data owner. In many cases this will be other USGS programs, in some cases other government agencies, and for most roads a commercial data provider. Actual correction of a data error is the responsibility of the data owner.
In most cases, a US Topo map will not be specially remade to correct an error. Instead, the data sources will be corrected for inclusion when the map is remade in the regular 3-year cycle. USGS believes that data sources will continually improve, and the quality and currentness of the map series as a whole is best served by a rapid refresh cycle rather than by giving special attention to an individual map.
