Workflow<\/strong><\/p>\n\n\n\n

– Elevation model, Orthophoto and laser scan data from Maanmittauslaitos (CC4)
– Import geotiff to Unity https:\/\/github.com\/unitycoder\/UnityGeoTiffImporter<\/a>
– Import .jp2 to Unity https:\/\/github.com\/unitycoder\/JP2Converter<\/a>
– Create terrain from geotiff elevation map (unity editor tool)
– Compare with laser scan data for real world size https:\/\/las2gltf.kelobyte.fi\/<\/a>
– Crop terrain and orthophoto for the game area (unity editor tool)
– Create lake depth map for the lake, if not available online (photoshop)
– Use lake depth map to lower terrain in lake area (unity editor tool)
– Get tree positions from orthophoto into CSV (python script)
– Plant trees to terrain (unity editor tool)
