Introduction
The national elevation models for Norway (DTM and DOM) are created by the Norwegian national ordnance survey (Kartverket).
These data-sets in windPRO come at a 10 meter grid resolution. They are generated primarily based based on laser scans - and are continuously updated.
The versions distributed in windPRO by EMD were downloaded during late August 2018.
Currently, we distribute the digital terrain model (DTM10) and the digital surface model (DOM10)
Availability from within WindPRO
The data are available directly from within windPRO in 10 meter resolution. The data can be accessed from the online-services in the following objects:
- Line Object (with purpose set to height contour lines)
- Elevation Grid Object (with data-type set to 'Elevation data')
- Elevation Grid Object (with data-type set to 'Surface data')
Data Type
The DTM10/DOM10 elevation data are delivered as gridded data with a spatial resolution of 10 meters. As a part of the processing of the DTM10/DOM10 elevation data from our EMD server, the user has an option of choosing whether the data downloaded should be received as either raw gridded data or converted to height contour lines. In order to use the data for energy yield calculations, the data must be converted to contours. For maximum spatial accuracy, we deliver the data in 3 UTM-zones. Coordinate systems used: ETRS 89 UTM Zone 32/33/35 (EPSG:25832, EPSG:25833, EPSG:25835)
Coverage
Coverage of the DTM10/DOM10 elevation data is mainland Norway, see here.
