Abstract

Drainage lines from digital elevation model in Oslo
Track: Water, Wastewater, and Stormwater
Authors: Webjorn Finsland

Surface water is a major challenge in many Norwegian cities. The city of Oslo has calculated drainage line using ArcGIS, vector data and Lidar data. This seems to correlate very well with areas with urban flooding problems. Drainage lines are therefore now used in planning. This is a story about how GIS is used to develop an idea to a useful planning tool. All without consultants.
