An Urban voxel model an example from I-Gis 4. Eksempel på resulterende voxelmodel 1. Drikkevand- og spildevandsledninger indlæst og vist i forhold til diameter 2. Voxelering af ledningsgrave for vand- og spildevandsledninger. Farverne indikerer variationer i sand og lerindhold i fyldet i de opfyldte ledningsgrave. 3. Udfyldning af de resterende voxler på baggrund af information fra udarbejdet geologisk model.
