Since 1993 EDCON-PRJ has been flying high-definition aeromagnetic surveys in north-central Nevada. Most of the surveys were flown with a line spacing of 200 meters, draped 150 meters above terrain. The data are being sold by 7½-minute quadrangles at a sliding scale cost per line-mile. Following are the acquisition specifications of each survey, deliverable products,
