GMS:Exporting Grids

2D and 3D grids can be exported from GMS in various formats by right-clicking on the grid in the Project Explorer and selecting the Export command. The options available include:

Exporting 2D Grids

1. Text GMS 2D Grid File (*.2dg)

   This is an older GMS grid file format that is described in this document.

2. ARC/INFO Ascii Grid File (*.asc)

   This is a raster format that can be opened in ArcMap. Because it's a raster, only use this option with cell-centered grids where all cells are the same size.

Exporting 3D Grids

1. Text GMS 3D Grid File (*.3dg)

   This is an older GMS grid file format that is described in this document.

2. Shapefile

   An ESRI ArcGIS compatible shapefile will be exported containing 2D polygons for all 3D grid cells in all grid layers. The attribute table fields include:

   • cell ID
   • cell I
   • cell J
   • cell K
   • grid cell activity
   • scalar dataset values (chose which datasets to save)
   • dataset activity (if it exists)

   A simple definition query using the grid cell activity and K fields can be created in ArcMap to see one layer of the grid at a time.
