📄️ Error Surfaces
Error surfaces are rasters that represent uncertainty within a DEM Survey. The values in an error surface possess the same vertical units as those of the corresponding DEM and also, since error surfaces belong to a parent DEM survey, there are specific requirements regarding these rasters. Error surface rasters and the parent DEM survey must have identical:
📄️ Reference Surfaces
Reference surfaces are elevation rasters that originate from some other source than a topographic survey. They are very similar to DEM Surveys in that they share the same vertical units, cell resolution and spatial reference. They can also be used as one or both surfaces in a change detection analysis.
