Stack Multiple 2D Grids in 3D Grid

(Select multiple 2D grid files with identical geometry)

Use this operation to convert multiple 2D grid files to a single 3D grid file. This is relevant when each of the 2D grid files represents an elevation (not depth), e.g., mean resistivity grid files commonly used in geophysical surveys.

After the 2D grid files have been converted to a 3D grid it can be shown in GeoScene3D as slices, node points, node cubes, iso surfaces as well as in profile windows.

It is required that all the 2D grid files have the same geometry. This means that they all must have the same min and max X and Y corner coordinates as well as the same number of nodes in X and Y. Furthermore, the 2D grid files must represent elevations that are evenly spaces in the vertical direction, e.g., elevation 0, 10, 20, 30, etc.

Grid Files: The grid files must be organized in the correct order. The grid with the lowest elevation at the bottom of the list and the grid with the highest elevation at the top of the list. Use the Up and Down buttons to organize the grid files.

Bottom Grid Elevation: The elevation for all other grids is calculated based on this value.

Vertical Grid Spacing: The elevation for all grids except the bottom grid is calculated based on this value.

Grid Value Type: Select the internal floating point grid value format. Single uses only half as much memory as Double. In most cases Single is sufficient and therefore the recommended setting.
