Directory Identifier: GRAVCD-isoreg Directory Title: U.S. Isostatic Regional Gravity Grid Principal Investigator: Numerous Contributing Organization: U.S. Geological Survey
Summary: isoreg.bin - standard grid containing sea level isostatic regional for the U.S. Grid interval = 8 km. Projection is Albers (central meridian = 96 degrees West; base latitude = 0 degrees North). Sea level depth of compensation = 30.0 km, density contrast at depth = 0.35 g/cm^^3. Values are in milligals. Data Records: The data are binary and are in 4 byte integers. The integer value must be divided by 100 to get the actual value with two digits to the right of the decimal point. Original File = 4,045,520 bytes 650 columns X 386 rows = 250,900 data NOTE: The binary files isores.bin, isoreg.bin, and isotop.bin were converted from the ASCII files on the Geophysics of North America CD-ROM by Ted Habermann. The data values were converted to 4 byte binary integers with two digits to the right of the decimal point. These integers must, therefore, by divided by 100 to recover the original data.
