The area was flown along a draped surface with a nominal survey height above ground of 125 meters. The flight line spacing was 250 meters for traverse lines and 2500 meters for control lines. Here we present downloadable magnetic data from those surveys as flight line data (csv format) or Geotiff images.\nLine data (EAdirondacksMag.csv) are presented as comma separated values with the following definitions (see technical report for details):\nLINE Flight line number\nDATE YYYY/MM/DD\nTIME Time (UTM, 24-hour) hh:mm:ss\nLONG Longitude, WGS84 (degrees)\nLAT Latitude WGS84 (degrees)\nx_UTM18N Easting, UTM Zone 18N, WGS84 (meters)\ny_UTM18N Northing, UTM Zone 18N, WGS84 (meters)\nRALT Radar altimeter height (meters)\nBALT Barometric altimeter height (meters)\nGPSZ GPS elevation (meters)\nDEM Digital Elevation Model (meters)\nINS_AZ Aircraft azimuth (degrees clockwise from North)\nINS_PITCH Aircraft pitch (degrees, nose up positive)\nINS_ROLL Aircraft roll (degrees, left wing up positive)\nRAWMAG Raw, compensated total magnetic intensity (nT)\nLRAWMAG Raw, compensated total magnetic intensity with lag correction (nT)\nBASEMAG1 Base Station 1 Magnetic field (nT)\nBASEMAG2 Base Station 2 Magnetic field (nT)\nLEVMAG Leveled total magnetic intensity (nT)\nMLEVMAG Micro-leveled total magnetic intensity (nT)\nIGRF International Geomagnetic Reference Field (IGRF) (nT)\nRESMAG Residual Magnetic Anomaly (MLEVMAG-IGRF) (nT)\nGeotiff images show the residual magnetic anomaly (file EAdirondacks_MagRes.tif). Images use projected coordinates (UTM 18N, WGS84); geotiff tags are embedded.
