The Earth MappingResources Initiative (Earth MRI)
This data release provides digital flight line data for a high-resolution airborne magnetic survey over the Hartville Uplift and Shirley Mountains regions of Wyoming. The survey is split into two blocks, one covering the Hartville Uplift region (Block A), and the other covering the Shirley Mountains region (Block B). The airborne survey was mainly funded by the State of Wyoming, with a smaller contribution from the Earth Mapping Resources Initiative (Earth MRI). The survey was designed by the Wyoming State Geological Survey (WSGS) and contracted by the USGS. The survey was designed to meet complementary needs related to geologic mapping and characterization of mineral resource potential. A total of ca. 83,000 line km of magnetic data were acquired over areas totaling ca. 15,000 km2. In the Hartville Uplift region (Block A), data were collected from a fixed-wing aircraft flown at a nominal terrain clearance of 100 meters (m) above topography along E-W flight lines spaced at 200 m intervals. Tie lines were flown in an N-S direction every 2000 m. In the Shirley Mountains region (Block B), data were collected from a helicopter flown at a nominal terrain clearance of 100 meters (m) above topography along N-S flight lines spaced at 200 m intervals. Tie lines were flown in an E-W direction every 2000 m. Data were collected by NV5 Geospatial, Precision GeoSurveys, and EDCON-PRJ under contract to the USGS using aircraft with magnetometers mounted in stingers. The survey operated out of airports in Casper, Lusk, and Torrington, Wyoming, from May to July of 2025. Files that are available in this publication include flight line data for the magnetic survey, and a report describing the survey parameters, field operations, quality control and data reduction procedures. A zip file is provided that contains the contractor's deliverable products that includes Geosoft databases and grids for the magnetic survey and the report describing the survey and data reduction.
The Hartville Uplift-Shirley Mountains survey was designed to meet complementary needs related to geologic mapping and mineral resource research.

Files that are available in this publication include flight line data for the magnetic survey in an ascii .csv file, flight line data for the radiometric survey in an ascii .csv file, geoTIFF images of the total magnetic intensity and radiometric total count, potassium, thorium, and uranium values, grids of these data, and a report describing the survey parameters, field operations, quality control and data reduction procedures. A zip file containing the contractor's deliverable products is also included. These files are provided as received from the contractor. Binary files in this package are readable using the free software "Geosoft Viewer"(https://www.seequent.com/products-solutions/geosoft-viewer/) or commercial software "Oasis montaj".

Daily quality control of airborne survey data was performed by the contractor:
The data from each flight were reviewed in three stages by separate individuals. The data were first reviewed by the pilot and crew immediately after each flight. Then the data were downloaded from the onboard computer and uploaded via ftp to EDCON-PRJ's offices in Lakewood, Colorado for formal quality review. In Lakewood, each flight's data were checked for uality by the staff of airborne data processors and geophysicists for EDCON-PRJ. The data were then compensated and corrected for diurnal activity using data collected from the base station magnetometers. Then the data were reviewed for flight line accuracy, GPS resolution, radar altimeter positioning, magnetometer noise levels, drape deviations, and spectrometer count levels, tuning, and resolution. Daily acquisition updates were forwarded via e-mail to the USGS staff. Two Geosoft databases for each block, one for magnetic data and one for radiometric data, were updated daily and posted to the USGS folder on EDCON-PRJ's ftp site for review.
Further quality control measures occurred post flight by the contractor and USGS scientist-in-charge before approval and acceptance of the final data. The data have been peer reviewed and compared with related ancillary data.
Data were visually inspected for reasonableness and spatial consistency.
Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.
Field quality control and assurance procedures were undertaken by the NV5 Geospatial, Precision GeoSurveys, and EDCON-PRJ field crew and are described in the contractors report included with this data release.
Field quality control and assurance procedures were undertaken by the NV5 Geospatial, Precision GeoSurveys, and EDCON-PRJ field crew and are described in the contractors report included with this data release.
The airborne survey was flown under contract with NV5 Geospatial, Precision GeoSurveys, and EDCON-PRJ from May 16th, 2025, and July 7th, 2025.

COG is a raster format for storing and serving georeferenced raster imagery on the web. It is a variant of the TIFF image format that specifies a particular layout of internal data in the GeoTIFF specification to allow for optimized (subsetted or aggregated) access over a network for display or data reading. GeoTIFF is a public domain metadata standard which allows georeferencing information to be embedded within a TIFF file. GeoTIFF were made using the Minimum Curvature gridding method to create grids of cell size of 50m (traverse/survey lines only). Point values in this geotiff represent grid values of the data and have not been normalized between 0 and 255.

Point values in this geotiif represent grid values of the data and have not been normalized between 0 and 255..

TMI-COG_AreaA_AirborneMagneticAndRadiometricSurveyHartvilleUpliftAndShirleyMountainsRegionsWY2025.tif is a Total Field Magnetic Anomaly (nT) grid in Cloud Optimised GeoTIFF format (COG). COG is a raster format for storing and serving georeferenced raster imagery on the web. It is a variant of the TIFF image format that specifies a particular layout of internal data in the GeoTIFF specification to allow for optimized (subsetted or aggregated) access over a network for display or data reading.
