Calculate Grid Response

Calculate a component of the model response across a rectangular area and export as a georeferenced grid. The output grid will be georeferenced using the Coordinate System and azimuth assigned to the model. The response may be calculated at a constant elevation or a constant terrain separation.

By default, the dimensions of the grid are taken from the current Plan View. You may want to refine an existing View or create a special View for this, so that the grid dimensions and location are exactly as you would like.

To Calculate Grid Response

On the Compute menu, select Calc Geosoft Grids. The Calculate Geosoft Grid Response dialog appears.
From the Param. to grid drop-down list, select the gravity or magnetic component whose response you wish to calculate.
On the Grid file field, browse to the output grid name and location.
From the Elevation(Z) drop-down list, select a Fixed Elevation or Terrain Separation (+up).
Specify the value and units.
In the Grid Size & Range box, specify the horizontal limits. The default values are taken from the current Plan View limits. Also, set the cell size and units of the grid.
Click Compute & Save. The Compute Grids progress bar appears and the grid is written.
