Rasters (Subsidence Overlay)

Jump to search
Raster data in the form of GeoTIFF Overlays or other Grid Overlays can be configured as prequels for the Subsidence model to initiate ground water levels and clay thickness.
Prequels
- High ground water level prequel (Subsidence Overlay)
- Low ground water level prequel (Subsidence Overlay)
- Clay thickness prequel (Subsidence Overlay)
Notes
- In case a prequel is used, respective feature data is ignored. For example, when a clay thickness prequel is configured, clay thickness values from terrain and areas are ignored. They do not override values in the prequel, even when the prequel's raster values are NO_DATA values.
