Questions & Answers
DAT files: Frequently Asked Questions
What are DAT files?
ZMap Plus Grid is an ASCII grid format of Landmark Graphics for exchanging gridded geological and geophysical surfaces. Comment lines begin with an exclamation mark, and the header opens with an at-sign line giving the grid name, the GRID keyword, and the number of nodes per line. The second header line defines the field width, the null value, an optional null string, the decimal places, and the starting column; the third lists the row and column counts followed by the minimum and maximum X and Y limits; a closing at-sign line ends the header. Node values follow column by column, starting from the westernmost column and running from the north edge to the south edge, with a null value, typically 1.0E30, marking undefined nodes. Conversion to graphics requires transposing this column-major order into row-major image order, deriving the cell size from the extents and counts, masking null nodes as transparent, and rescaling values to an 8-bit or 16-bit grayscale or color-ramped image in PNG, JPEG, or TIFF, while GeoTIFF preserves floating-point values and extents. Supported by Petrel, Surfer, and Global Mapper.
