This map is for information only and may not be used for legal purposes. Distances are approximate and may not be suitable for navigation. The information on this map is derived from numerous sources, and no warranty is provided for the map or its features to be spatially or temporally accurate.


OffTheGridMaps wouldn't be a reality without a lot of support, both on a technical level and personal level.  We'd like to acknowledge all of the free and open source data sources and software that have helped us produce these amazing maps.

Data Sources

One of the best things about the GIS and mapping industry is the availability of data, especially in the state of Montana.  Government agencies are generally the best source of spatial data, and Montana has a great culture of publicly sharing this data widely and freely.

In order to make the most comprehensive OffTheGridMaps possible, we incorporate data collected from dozens of public and private sources including Federal, State, and local governments and special interest groups.  Some of the key data sources we rely upon to keep our maps up-to-date include:

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.


None of this could be done without quality software.  And there is some great open-source software that is freely available to the public.  What are the key pieces of software we use?

Friends, Family, Colleagues

There's too many to name, and if we started putting pen to paper, we'd probably miss someone.  So for those of you who have provided content and layout ideas, as well as business advice, just know we are incredibly grateful for your contributions!  We couldn't have made it this far without your help!
