Errors and Omissions

While we make every effort to keep our maps accurate and free of errors, most of the information on our maps is derived from other sources.  Unfortunately, that means no warranty is provided for the map or its features to be spatially or temporally accurate.

If you do find an error or omission, please consider contributing your changes or recommendations in these three ways:

  • Contact the source
    If you are familiar with who manages a particular map data source, please contact the authoritative data source as listed above.
  • Contribute to OpenStreetMap
    If you are not already familiar with OpenStreetMap, you should really check it out.  "OpenStreetMap is a map of the world, created by people like you and free to use under an open license."  To learn how to contribute to this free global map, please read the OSM Beginners Guide.
  • Contact Us
    Finally, please feel free to contact us and report anything on the map you feel is in error. We'll try to make the changes as soon as possible and contact the source of the data on your behalf.
