The goal of the Alaska Division of Geological & Geophysical Surveys' (DGGS) Airborne Geophysical/Geological Mineral Inventory (AGGMI) program is to enhance the understanding of Alaska's mineral resources and stimulate private-sector mineral development. The program seeks to delineate mineral zones on Alaska State lands that: (1) have major economic value; (2) can be developed in the short term to provide high-quality jobs for Alaskans; and (3) will provide economic diversification to help offset the loss of Prudhoe Bay oil revenue. Candidate lands for this program are identified on the basis of existing geologic knowledge, land ownership, and nominations from Alaska's geologic community. The AGGMI program and resulting new geologic knowledge are recognized worldwide and have encouraged millions of dollars of venture capital expenditures in the local economies of the surveyed mining districts. These venture capital expenditures have led to discovery and delineation of new mineral resources. The multi-year Strategic and Critical Minerals Assessment Capital Improvement Project (SCMA) was established to determine Alaska's geologic potential for rare-earth elements and other minerals that are essential for our modern, technology-based society. This program began in FY2012 with a data survey and compilation of existing information on rare-earth-element occurrences in Alaska, and expanded significantly in FY2013 to include additional critical minerals, re-analyses of existing samples, and obtaining new field and analytical data, including airborne geophysics.\n>idi_ani_slt_bvc_fxh_sdr: Geosoft-format binary grids, GeoTiff format gridded data images, KMZ/KML files, Geosoft ASCII polygon files (PLY), Geosoft ASCII zone files, ESRI Shapefiles, and ERMapper files. Note: these data are provided in both UTM Zone 4 - NAD27 and Geographic WGS84 projections. The data files were compiled from the Beaver Creek, Fox Hills, Southern Dishna River, Aniak, Sleetmute, Iditarod geophysical surveys.\n\n\n\n\n2000\n2013\n\n\nground condition\n\n\nplanned\nAs needed\n\n\n\n-159.363394\n-156.204523\n63.171061\n61.484406\n\n\n\n\nISO 19115 Topic Category\ngeoscientificInformation\n\n\nAlaska Division of Geological & Geophysical Surveys\nAirborne Geophysical Survey\nElectromagnetic Data\nElectromagnetic Survey\nGeophysical Map\nGeophysical Survey\nGeophysics\nGeophysics Search Tag\nGridded Data\nMagnetic Data\nMagnetic Survey\nMagnetics\n\n\nAlaska Division of Geological & Geophysical Surveys\nAlaska, State of\n\n\nThis report, map, and/or dataset is available directly from the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (see contact information below).\nAny hard copies or published datasets utilizing these datasets shall clearly indicate their source.

The geophysical surveys were managed by State of Alaska, Department of Natural Resources (DNR), Division of Geological & Geophysical Surveys (DGGS).

These exceptions did not noticeably impact data quality. Additional detail about contract specifications and operational issues can be found in the metadata of the originating surveys.\n\nThese data originate from multiple similar geophysical surveys with different specifications. Reference the metadata of each originating survey for exact specifications.\nHelicopter and fixed wing geophysical surveys often have small data gaps that do not negatively impact the overall quality of the final products. Reference the metadata for each originating survey for specific details.\n\n\nAll originating data were positioned by DGPS (Differential Global Positioning System) with an accuracy of 5 meters or better.\n\n\n\n\n\n\nBurns, L.E.\n2000\nPortfolio of aeromagnetic and resistivity maps of parts of the Aniak and Iditarod mining districts, southwestern Alaska\n\nGeophysical Report\nGPR

gridded data from the Beaver Creek, Fox Hills, Southern Dishna River, Aniak, Sleetmute, Iditarod geophysical surveys were merged with previously created merged grids from the older surveys, Iditarod, Aniak and Sleetmute survey blocks, using Oasis Montaj techniques. A merge of the residual magnetic data was possible for all areas. The Beaver Creek, Fox Hills, Southern Dishna River, and Iditarod diurnally corrected data were adjusted for regional variations, i.e. IGRF gradient, 2010, updated to the date of data acquisition and adjusted for altimeter variations on a point by point basis. The older surveys, Aniak and Sleetmute, would have been adjusted for regional variations based on the IGRF of a single point in the middle of the survey area, and a single height and date. The residual grids of all the areas may therefore have different base values dependent on the IGRF model used because of the time elapsed between the flying of the first and last surveys. The grids were adjusted to each other prior to the final merge. The apparent resistivity grids for 56,000 Hz, 7200 Hz, and 900 Hz coplanar EM data were merged with no reprocessing, as general processing methods and more importantly background resistivity values for all frequencies have not changed since the original merge of the Aniak and Sleetmute data in 2003. Oasis Montaj has the capability to merge or stitch two or three grids together. The process requires overlap between adjacent grid areas. There is also the option of selecting different grid stitch techniques. For this project the standard \"Suture\" technique with the 'No De-trending' option was selected. The process requires selecting a \"master\" grid or the grid that all other grids will be levelled to. The grid that was published first is usually chosen and the grid from the most recent survey was selected as the secondary grid (i.e. the grid that will be DC shifted to the master grid). .\n2013\n\n\nBoundary - DGGS staff constructed a boundary of the merged grid file. The grid boundary was constructed using Geosoft Oaisis montaj grid outline and map export functions. The boundary file is available in Geosft PLY ASCII format and ESRI Shapefile format.\n2017\n\n\nGoogle Earth KMZ files - DGGS staff created Google Earth KMZ/KML files from the grid files data using ESRI ArcGIS software.\n2019\n\n\n\n\nraster\n\n\n\n\n\nUniversal Transverse Mercator\n\n4\n\n0.999600\n-159\n0\n500000.000000\n0\n\n\n\n\ncoordinate pair\n\n.00000001\n.00000001\n\nMeters\n\n\n\nNorth American Datum of 1927\nClarke 1866\n6378206.40000000037\n294.978698199999997\n\n\n\n\n\n\nidi_ani_slt_bvc_fxh_sdr\nGeosoft-format binary grids, GeoTiff format gridded data images, KMZ/KML files, Geosoft ASCII polygon files (PLY), Geosoft ASCII zone files, ESRI Shapefiles, and ERMapper files.
