Convert Elevation Grid to Surface

Use the Convert Elevation Grid to Surface option (geogxnet.dll(Geosoft.GX.Surface.ImportGridToSurface;Run)*), to convert the X,Y,Z points in an elevation grid to vertices of an equivalent relief surface. The resulting surface may be saved to either a new or an existing geosurface file. If a 3D View is open in your workspace, the target geosurface file will be displayed.

You can access the option from:

The Oasis montaj Geosurface > Utilities > Convert Elevation Grid to Surface menu
The Oasis montaj 3D View > Geosurface > Utilities > Convert Elevation Grid to Surface menu
The 3D Viewer Geosurface > Utilities > Convert Elevation Grid to Surface menu

Convert Elevation Grid to Surface dialog options

Elevation grid	Specify the name of the input relief grid. The grid cannot have a section orientation. Script Parameters: IMPORTGRID2SURF.INPUT_GRID
Output geosurface	Specify the name of a new or existing geosurface file. Script Parameters: IMPORTGRID2SURF.OUTPUT_SURFACE_FILE
Surface name	Select a name for the new surface. By default, it will be the root name of the input grid. Script Parameters: IMPORTGRID2SURF.OUTPUT_SURFACE_NAME
Colour	Select a colour for the surface. The default colour is Magenta. Script Parameters: IMPORTGRID2SURF.SURFACE_COLOR

Application Notes

*The GX tool will search in the "...\Geosoft\Desktop Applications \gx" folder. The GX.Net tools, however, are embedded in the geogxnet.dll located in the "...\Geosoft\Desktop Applications \bin" folder. If running this GX interactively, bypassing the menu, first change the folder to point to the "bin" folder, then supply the GX.Net tool in the specified format.

Requirements

The input grid must be an elevation grid; section grids are not allowed.
The Z-values in the grid are interpreted as elevations using the same distance units as the coordinate system; i.e., X, Y, and Z are all the same units. Each node in the grid results in a node on the triangulated surface.
