Mine Resources-GIS Map of North Country National Scenic Trail and Vicinity, MI, MN, ND, NY, OH, PA, VT, WI

Geologic and Soil Resources Inventory (GSRI)

NOT FOR PUBLIC DISTRIBUTION, FOR NPS USE ONLY. This dataset is composed of GIS data layers, Mine Area Features (NOCOMAF), Mine Point Features (NOCOMIN), USGS 7.5' Quadrangles (QUAD_7DOT5MINUTE) and NOCO Trail Trace (TRAIL_TRACE), deemed has sensitive data, and therefore should not be distributed outside the NPS or to non-approved users. This sensitive GIS Data is available in the following GRI-supported GIS data formats: 1.) an Esri file geodatabase (noco_mine_resources_sensitive.gdb). The file geodatabase format is supported with a 1.) ArcGIS Pro 3.X map file (.mapx) file (noco_mine_resources_sensitive.mapx) and individual Pro 3.X layer (.lyrx) files (for each GIS data layer), and 2.) a Open Geospatial Consortium (OGC) geopackage. Upon request, the sensitive GIS data is also available in Esri shapefile format. Contact Rebecca Port at rebecca_port@nps.gov (see contact information below) to acquire the GIS data in shapefile format. In addition to the GIS data and supporting GIS files, two additional files comprise a GRI digital mine_resources-GIS dataset or map: 1.) a readme file (noco_mine_resources_gis_readme_sensitive.pdf) and 2.) a user-friendly FAQ PDF version of the metadata (noco_mine_resources_metadata_sensitive_faq.pdf). Please read the noco_mine_resources_gis_readme_sensitive.pdf for information pertaining to the proper extraction of the file geodatabase and other map files. The data were completed as a component of the Geologic Resources Inventory (GRI) program, a National Park Service (NPS) Inventory and Monitoring (I&M) Division funded program that is administered by the NPS Geologic Resources Division (GRD).

For more information about the Geologic Resources Inventory Program visit the GRI webpage: https://www.nps.gov/subjects/geology/GRI.htm.

Source maps and data used to complete this GRI digital dataset were provided by the following: U.S. Geological Survey, Environmental Systems Research Institute (Esri) and North Country Trail Association. Detailed information concerning the sources used and their contribution the GRI product are listed in the Source Citation section(s) of this metadata record (noco_mine_resources_metadata_sensitive.txt or noco_mine_resources_metadata_sensitive_faq.pdf). Users of this data are cautioned about the locational accuracy of features within this dataset. Based on the source map scale of 1:24,000 and United States National Map Accuracy Standards features are within (horizontally) 12.2 meters or 40 feet of their actual location as presented by this dataset. Users of this data should thus not assume the location of features is exactly where they are portrayed in ArcGIS Pro or other software used to display this dataset. All GIS and ancillary tables were produced as per the NPS GRI Geology-GIS Geodatabase Data Model v. 2.3. (available at: https://www.nps.gov/articles/GRI-geodatabase-model.htm). Product adapted from a U.S. Geological Survey data release map by Horton and San Juan (2016), a U.S. Geological Survey Digital Data Series DDS-52 map by McFaul, Mason, Ferguson, and Lipin (2000), a Feature Service map by Esri (2025), and a Feature Service map by North Country Trail Association (NCTA) (2025).
