Grid Adjustment and Evaluation

The grid adjustment and evaluation feature adjusts grids (surfaces). The adjustment is based on a grid order, min and max distance between grid pairs, and max allowed grid adjustment. This type of adjustment is often applied in hydro stratigraphic modeling.

The method does not change the existing grids but produces a new set of grid files. In addition, a set of grids containing the amount of adjustment for each grid and a set of isopach grids for the resulting layer thicknesses can be generated after adjustment.

This feature works directly on the entire source grid files - not only within scene extent.

Only Surfer grid files and ASCII grid files are supported. All grid files must be online.

Adjustment
Creates or updates a set of grid files based on the adjustment setup. The adjusted grid files will be added or updated as surfaces in the Object Manager.

Postfix: Post fix used for new object group and generated grid files.
Setup / Execute: Shows the Grid Adjustment dialog and performs the grid adjustment

Generate Difference Grids
Creates or updates a set of grid files containing the amount of adjustment in each grid. These grid files are not added as objects in the Object Manager but can be added manually to a map.

Postfix: Post fix used for generated grid files.
Execute: Generates difference grid files

Generate Isopach Grids
Creates or updates a set of grid files containing the resulting layer thicknesses. The thickness is calculated as the distance to the grid file above. These grid files are not added as objects in the Object Manager but can be added manually to a map.
