Metadata for Report 231 [UPDATED September 26, 2016]

A Compilation of Ore Mineral Occurrences, Drill Core, and Testpits in the State of Minnesota; literature search on publicly reported mineral occurrences.

Data is divided into the following folder directories:

'ORIGINAL_ASC': Original .asc data files from report 231

'ACCESS': Access database with three tables (drill231, r231, tescrop) imported from the original .asc files seen above

'DBF': .dbf data files exported from the three tables (drill231, r231, tescrop) used to create ESRI spatial data of both shapefiles and a file geodatabase.

'SHP': 5 point shapefiles (drill231.shp, tescrop.shp, r231.shp, r231tab_that_do_not_have_mincodes.shp, r231tab_that_have_mincodes.shp) created in ArcMap by using the UTMX and UTMY fields in the original ASC file and projected in Nad83 UTM Zone 15N. A new GIS dataset (r231_sections_with_links_to_report) displays the single or compiled Public Land Survey (PLS) sections that are documented in Report 231. Each polygon record contains an online URL which will display the report text for that area. Also of note that the DNR extracted those 'r231tab.shp records that have MINCODES to 'r231tab_that_have_mincodes' and those that don't to 'r231tab_that_do_not_have_mincodes'. The reason behind this was to highlight those records with mineral occurence codes in a new ArcGIS map service. ArcGIS map service can be found online at:
http://arcgis.dnr.state.mn.us/arcgis/rest/services/lam/mndnr_231_1985_mineral_occurences/MapServer or at the DNR's Drill Core Library Web Map Application at: http://mndnr.maps.arcgis.com/apps/webappviewer/index.html?id=0ef01d29d52b4efbb9694f042e83f413

'FILE_GDB' - All shapefiles above compiled into one file geodatabase.
