When I import a RAW grayscale heightmap for a terrain layer I am facing the issue that only the lowest and highest points of the terrain have the expected height, but heights in between are off. I tested this by placing little cubes according to the geospatial data that I am working with. There I saw that there always is a big difference between the cubes and the actual terrain. My workflow is the following: I open the ASC-File containing the terrain data in QGIS (tool for geospatial data) -> I export a rendered grayscale TIF file from QGIS -> opened in Photoshop -> changed image size to 4097x4097 and set the mode to 16-bit grayscale -> exported as RAW file -> imported as terrain heightmap in Unity -> set y coordinate of the terrain to the lowest height of the terrain which is shown in “QGIS” and for the terrain height I used the difference of the highest and the lowest elevation You can find the relevant files on my googledrive as they were to large for upload on the https://drive.google.com/file/d/1zjwLPxe7jT5SNuT-iwUBSIiWoqT5FKXO/view?usp=sharingforum. I also tried directly creating the RAW file from the ASC file using the tool “GDAL” but this resulted in a completely flat terrain. I would really appreciate it if someone could help me. I am struggling with this for quiet a while and I really must solve this as it is very important for my bachelor thesis.
