subset horizons

The subset horizons module allows you to subset the output of gridding and horizons so that downstream modules (3d estimation, horizons to 3d, Geologic Surface) act on only a portion of the layers kriged.

subset horizons is used to select a subset of the layers (and corresponding surfaces) export from gridding and horizons. This is useful if you want (need) to krige parameter data in each geologic layer separately.

This is not normally needed with contaminant data, but when you are kriging data such as porosity that is inherently discontinuous across layer boundaries, it is essential that each layer be kriged with data collected ONLY within that layer.

subset horizons eliminates the need for multiple gridding and horizons modules reading data files that are subsets of a master geology. Inserting subset horizons between gridding and horizons and 3d estimation allows you to select one or more layers from the geology.

This functionality is very useful when you want to krige groundwater and soil data using a single master geology file that represents both the saturated and unsaturated zones.

Module Input Ports

• Input Geologic Field [Field] Accepts a data field from gridding and horizons to krige data into geologic layers.

Module Output Ports

• Geologic legend Information [Geology legend] Supplies the geologic material information for the legend module.
• Output Geologic Field [Field] Can be connected to the 3d estimation, 3D_Geology Map, and surface from horizons(s) modules.
