Most of Nevada is covered by proprietary, nonexclusive aeromagnetic data flown between 1978 and 1988. These aeromagnetic data are superior to those available in the public domain for several reasons. The surveys were flown to uniform specifications; the profile data are available and are in digital form; the surveys were flown on a square grid,
Survey Size: 13,100 miles Flight Lines: North-South, 1 kilometer spacing Tie Lines: East-West, 2 kilometer spacing Elevation: 500 feet above ground level Instrumentation: High-sensitivity Cesium vapor magnetometer Data Provided: Total Magnetic Intensity (IRGF removed) contour map Flight Path Map Reduced-To-Pole of TMI map Vertical Derivative map (optional) Horizontal Gradient (optional) Profiles, on paper (optional) CD/DVD
Survey Size: 45,500 miles Flight Lines: East-West, ½-mile 1-mile, and 2,250 feet spacing Tie Lines: North-South, 5-mile spacing Elevation: 4,700 feet barometric, draped over higher elevations Instrumentation: Geometrics G-813 magnetometer, 0.05 gamma sensitivity Date Flown: December, 1985, to April, 1986 Data Provided: Total Magnetic Intensity (IRGF removed) contour map Flight Path Map Reduced-To-Pole of TMI
In 1999 PRJ flew a high-definition aeromagnetic survey in south-central New York that covers the current area of exploration for Trenton-Black River gas reservoirs. The survey covers an area of over 2.2 million acres. Survey Size: 13,675 line miles Flight Lines: North-south, 1/3-mile line spacing Tie Lines: East-west, 1-mile line spacing Elevation: 500 feet above
Survey Size: 4,500 line miles, 1,008 square miles Flight Lines: North-South, ¼-mile spacing Tie Lines: East-West, 5-mile spacing Elevation: 300 feet mean terrain clearance Data Provided: Total Magnetic Intensity (IRGF removed) contour map Flight Path Map Reduced-To-Pole of TMI map Vertical Derivative map (optional) Horizontal Gradient (optional) Profiles, on paper (optional) CD/DVD with Flight Line
