Survey Size: 2,424 miles Flight Lines: East-West, 1-mile spacing Tie Lines: North-South, 20-mile spacing Elevation: 1,000 feet above ground level Instrumentation: Geometrics G-803 magnetometer Date Flown: March, 1984 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)
Data for the four individual blocks have been integrated using a grid-based differential continuation onto a sloping plane (1500′ above sea level SE to 3700′ above sea level NW) to produce a single grid over the entire survey area. This gridded data set with maps is available as an optional deliverable. Survey Size: 5,198 line
Survey Size: Approximately 14,945 line miles Flight Lines: East-West, ¾-mile Tie Lines: North-South, 3-mile spacing Elevation: Approximately 5,500 to 6,000 feet barometric Data Provided: Maps, scale 1:24,000 Total Magnetic Intensity (TMI) Contour Map, IGRF-removed, showing the flight line locations, on paper Color Map of Reduced-to-Pole TMI, on paper Profile data and grids on CD-ROM Total
