Introduction
The Danish Elevation Model dataset (DHM - Danmarks Højdemodel) holds records of the heights in the Danish landscape with reference to the sea as its basic zero-level.
The Danish Elevation Model data is available in WindPRO in different four different verions: one based on gridded raw data sources and three based on raw vector data sources. The data sources are (with the official Danish name given last):
- DHM 10m gridded data - DHM/Terræn
- DHM 2.5m contour lines - DHM/Højdekurver
- DHM 5.0m contour lines - DHM/Højdekurver
- DHM 10.0m contour lines - DHM/Højdekurver
Please note, that these datasets were updated early 2013. Also, note the official danish name of the Dataset, as this needs to be acknowledged when using the data in your own applications.
Coverage
These dataset covers Denmark, see the picture to the right.
Availability in WindPRO
The all four datasets are available from the WindPRO online services.
Licence and Acknowledgement
The data is distributed according to the terms for use of free geographical data in Denmark: 'Terms and Conditions'. As stated in the conditions, please take proper care to add proper attribution in order to acknowledge the source of information. Typically, this is done by adding the following statement to your report-picture or map:
In Danish:
Indeholder data fra Geodatastyrelsen, [datasæt-navn], [år]
In English:
Contains data from the Danish Geodata Agency, [dataset-name], [year]
Raw Data
Contour lines originate from DHM/Højdekurver: That is, the three contour lines datasets (with 2.5m, 5.0m and 10.0m contour separation) were process by EMD from the original dataset with lines in 0.5 m contour separation. The raw contour data is available in either TAB or SHP format (i.e. map formats for MapInfo or ArcMap). Vector data originate from DHM/Terriæn.
