Introduction
The national elevation model for Norway, created by the national ordnance survey (kartverket). This data-set consists of a 10 meter grid. It is continuously updated: the version distributed by EMD was downloaded during late August 2018.
The national elevation model was finalized in 2013 using airborne laser scanning.
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
Data Type
The DTM Elevation Data are delivered as gridded data with a spatial resolution of 10 meters. As a part of the processing of the DTM 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.
The elevation grid is in coordinate system: ETRS 89 UTM Zone 32/33/35 (EPSG:25832, EPSG:25833, EPSG:25835)
Coverage
DTM-Elevation data, covers mainland Norge, see [here].
