NMMR Map Acquisition

The NMMR acquires maps through a vigorous outreach program directed at the public and state and federal environmental agencies. Other sources include:

  • Mining companies
  • Engineering and consulting firms
  • Surveying companies
  • Universities
  • Private citizens

We are always looking for donations of mine maps to add to our microfilm/digital collection. If you have mine maps you would like to donate see the contact information below.

When maps are received from a donor they are scanned and converted to microfilm, and placed in the archive. The maps, along with a scanned images are returned to the donor. Please don't hesitate to contact the Repository if you have any questions or wish additional information.

NMMR Procedures:

As maps are obtained at the Repository, they are assigned a unique six-digit identification number (document number). Data sheets are prepared for each map giving all available information including: map document number; state; county; mine name; mine ID number (MSHA); company name; mine type; and location coordinates of the geo-located point on the map. This information is added into the Repository's database. The maps are then scanned into a digital format and stored on the Repository's various mass storage arrays. The digital files are converted to microfilm for permanent storage in our archive.
