and look at the metadata section for the minimum and maximum values. You can find the real min/max using QGIS, or use the gdalinfo command line gdalinfo -mm "source.tiff" Data visualization using Google Earth Engine Apps. That will output a Unsigned Integer 16 bit png, with your float values mapped across the full 16-bit range of values. This section will cover how to find your heightmap and where to download it from. Make sure you set the MAX value to the full range, or the heightmap will be clipped, giving an appearance of mesas. Replace MIN and MAX in that command with the minimum/maximum values in your raster. I don't think you can do this from QGIS (correct me if I'm wrong)Īssuming you've got a 1-band raster with float values in the range MIN to MAX, you can use gdal_translate -of PNG -ot UInt16 -scale MIN MAX 0 65535 "source.tiff" "output.png" The application contains a bitmap editor for creating tiles and sprites and a map editor for designing level maps. Setup: Set your terrain size to 2048×2048, experiment with your height to get until you get the desired effect. You should be able to run this from the terminal (linux/mac) or the osgeo4w shell (windows). Heightmaps are an ideal way to store digital terrain elevations compared to a regular polygonal mesh, they require substantially less memory for a given level of detail. You can do this with the command line tool gdal_translate. I am using a 2k Terrain in WC then using that same 2k info as a heightmap in Unreal Engine to get. If that's the case it's because you're outputting 8 bit png, which only has 256 possible values. Tutorials - Free Terrain Heightmap for UE4, USD 0.00. I'm guessing that you're seeing quantization - the output comes out looking "terraced", like rice fields.
