ZMap / ZMap+ grid format

A regular ASCII grid in the Petrel / IHS ZMap+ format (*.dat). Import and export are both supported.

For more information refer to Import grids and Export maps

IRAP classic grid format

The Roxar / RMS IRAP classic ASCII grid (*.irap / *.gri / *.txt), identified by a -996 magic number in the header. Import only.

The header records the number of nodes, the node spacing, the coordinates of the south-west corner and the rotation angle of the grid, so a rotated grid keeps its orientation when it is imported. Values of 9999900 and above are the undefined value of the format and are imported as undefined nodes. Only the ASCII variant is read: a file that does not start with the -996 magic number is reported as a header error and is not imported.

Note

3D reservoir grids (ECLIPSE / GRDECL) are described in Grid Data Formats, and 3D model / geobody formats in Model Data Formats.
