User:Rcorrigan/AHGW Pro:Rasters to GeoVolumes
The Rasters to GeoVolumes tool is accessed by double-clicking on "
Rasters to GeoVolumes" under the "
Features" toolset under the " Subsurface Analyst" toolset under the "
ArcHydroGroundwater.pyt" toolbox. This tool creates new GeoVolume features from a mosaic dataset representing a depositional sequence. Horizons are used to build the GeoVolume features traversing the horizons from bottom to top and filling between the current horizon and the uppermost surface of all prior horizons. Each horizon is represented by a raster in the mosaic dataset.
- ArcGIS Notes – In older versions of ArcGIS, this tool is accessed through the "Arc Hydro Groundwater Tools" toolbox and appears as a dialog.
- The icons vary between ArcGIS and ArcGIS Pro.
- The order of the fields may vary between ArcGIS and ArcGIS Pro.
- In ArcGIS there are raster catalogs, but not in ArcGIS Pro. In ArcGIS Pro, mosaic datasets serve a similar purpose to raster catalogs. For ArcGIS, when this document says "mosaic dataset" it usually means "raster catalog".
- The names of the fields in this tool might be different in ArcGIS.
The following fields are available. Required fields are marked with a 
icon. In ArcGIS, they are marked with a 
icon. Fields marked with a 
icon may either not be supported or the table doesn't exist.
Input Projection Tin – Click the 
button to bring up the Input Projection Tin dialog in order to specify the TIN used to define the boundary of the GeoVolume features to be created. Triangles inside the TIN are used to define the triangle strips in the multipatch GeoVolume features.- Input Raster Catalog – Click the button to bring up the Input Raster Catalog dialog in order to specify the mosaic dataset containing rasters for each horizon.
- Raster Catalog Horizon ID field – Select from the drop-down the field in the mosaic dataset containing the horizon ID of the rasters. Each horizon ID should be unique.
- Minimum MultiPatch Thickness – Enter the minimum thickness of multipatch GeoVolume features to create. If the thickness between the top and bottom elevations for a triangular section of the GeoVolume is less than the minimum thickness value, the GeoVolume feature will not be created for that section.
- Input GeoVolume Features – Click the button to bring up the Input GeoVolume Features dialog in order to specify the GeoVolume feature class where new features will be created.
- Raster Catalog Clip field – Optional. Select from the drop-down the field in the mosaic dataset used to specify certain rasters as clipping planes. If a raster is specified as a clipping plane, then elevation values on horizons below that raster will be clipped to the raster if they are greater than the clipping raster. The Clip field should contain the following values:
- "0" – The raster is not used for clipping (default value).
- "1" – The raster is used for clipping horizons below it.
- Raster Catalog Fill field – Optional. Select from the drop-down the field in the mosaic dataset used to specify how the horizons are built between Horizon IDs. The Fill field should contain the following values:
- "0" – Do not fill between a lower HorizonID and a higher one.
- "1" – Fill between a lower HorizonID and a higher one (default value).
- Raster Catalog HGUID field – Optional. Select from the drop-down the field in the mosaic dataset containing the Hydrogeologic Unit identifier, as part of the Arc Hydro Groundwater Data Model.
- Append to Existing GeoVolume Features – Turn on to append new GeoSections to the feature class. Turn off to clear the target feature class prior to creating new GeoSections.
