Mineral Exploration Document Areas - Minarchive: Minnesota
- Minnesota Department of Natural Resources (DNR)
- Spatial (GIS) footprints that connect to more than 10,000 scanned mineral exploration documents indexed by the Minnesota DNR's Lands and Minerals Division between 1999-2001. The inventory was called Minarchive and resulted in a searchable website at: http://minarchive.dnr.state.mn.us/. The GIS footprints from this project were reviewed and attributes modified in order to make certain that each footprint had a relationship to one or more online exploration documents. These footprints are being made available to assist users in their search for mineral exploration documents in GIS software and/or online web map applications. A PDF report organized by Minarchive mineral exploration area (Spatial_ID) was developed to give general information on each document as well as provide online links to download PDFs and georeferenced maps. http://files.dnr.state.mn.us/lands_minerals/minarchive_collections/minarchive_report_links_october_2016.pdf Also included is a related GIS dataset featuring the footprints of selected Minarchive exploration documents georeferenced by the DNR between 2014-2016. This dataset has links to download the selected georeferenced maps. There are many more maps in Minarchive that can be geoferenced. Lastly included is a DNR pilot project that captured GIS data from georeferenced maps in a specific area of Northern Minnesota called the Cook Area. Data collected includes grids, bedrock outrcrops, and various point features such as drill holes or surface samples.
