EDCON-PRJ flew a high-resolution aeromagnetic (HRAM) survey in north-central Pennsylvania in 2007. The original participants in the survey had proprietary use of the data for twelve months following delivery. This proprietary period ends July 10, 2008 when the data become available for license to interested parties. The area of the survey is as shown on
Survey Size: Michigan Upper Peninsula 32,400 miles Flight Lines: NE-SW, ⅛ mile (200 meters) Tie Lines: NW-SE, 1 mile (1600 meters) Elevation: low level 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
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
