Data Download

1.  Visit the Data URL → https://dataforsyningen.dk/data/930

   

2. On the Download part of the screen, find the GeoTIFF terrain data. Note that these data are offered at 10 km blocks. 
   

3. Click on the Select Area button of Step 3 and select the tile including your area by navigating on the map provided. 
   

   After selecting the tile on the screen, click Order.
   
   Download the selected data as a zip.

Use Data for Terrain Model creation

After downloading the data, you can now proceed with creating a terrain model in CAD.

1. In AutoCAD or BricsCAD, go to the Plex-Earth ribbon → click on the Create Terrain dropdown box → Terrain from GeoTIFF → load the GeoTIFF downloaded.

2. In the Import GeoTIFF palette, specify the area by clicking on the Select Area button, then use your mouse cursor to draw a rectangle, and select the desired resolution using the slider.

3. Click on the Import Terrain button

4. Select the Surface Type from the options available:

   • Contour Polylines

   • Points

   • TIN Mesh

   • Civil 3D Surface

   • Create Terrain Model

For the first four options, CAD objects are directly imported, ready to be used in CAD or other software.

The last option creates a Plex-Earth terrain model, which can be saved in your DWG, and with the help of Plex-Earth, customize the terrain further and also insert the data as CAD objects later on.

ℹ️ NOTE: For this tutorial process, it is not mandatory to apply a coordinate system before working with the GeoTIFF, as Plex-Earth will automatically detect it from the file. The coordinate system applied can be changed using the Change Coordinate System button, if needed.

Here is the result!
