A GeoFormula is a powerful yet simple script that specifies mathematical or logical combinations of your geodata input to create a new raster object or virtual layer for a "data fusion" effect. Simply write an equation that defines how data in one or more objects are to be processed or combined.
Using GeoFormula layers in the Display process lets you automatically locate and combined objects on-the-fly, quickly display the script output, easily make adjustments to your script, and re-display the new results.
Alternatively, when you create a new raster in the standalone GeoFormula process it displays faster than the virtual GeoFormula layer, lets you use the new raster in other processes, and is easy to share output with others.
Several sample GeoFormula scripts have been prepared and are made available to illustrate scripting techniques and give you models to copy and adapt for your own needs.
