Finland Lakes, Eskers & Bogs Real-World Terrains 6 km

The lakes, eskers, bogs and glacier-polished granite hills of Finland at their real size, at 2.97 m resolution

80 heightmaps of Finland from real-world elevation data (DEM). Lake mazes with rocky islands, long esker ridges, open bogs, drumlin fields and low granite hills of the Finnish lakeland. Each map covers 5.988 x 5.988 km (about 6 x 6 km, 36 square km) at 2.97 m between samples. Every Unity terrain sample is an original heightmap pixel - nothing is stretched or resampled - and 1 Unity unit is 1 metre.

​

✦ WHAT'S INSIDE

• 80 heightmaps - 16-bit PNG, 2017 x 2017 px, relief from 20 m to 164 m per map
• One Unity terrain per map - 2049 samples at the map's own spacing; the unused 32-sample strip at the edge is cut away with terrain holes
• 3 demo levels x 3 render pipelines - 9 ready scenes to fly or walk through: Lake Maze, Esker Islands, Bog Plain and Streams
• Terrain Builder - one click turns any heightmap into a real-scale Unity terrain
• Finland ground look - 8 ground layers in 4K (meadow, forest floor, dry earth, scree, rock, gravel, bog, lake bed)
• Water - lakes with natural waves travelling across the surface, soft shorelines and deeper water towards the middle, in Built-in, URP and HDRP
• Bogs - open sphagnum mire painted on the smooth, wet flats of the data in the demo levels

​

✦ FEATURES

• Exact scale - size and height range are in every file name and inside every PNG, and the builder reads them for you
• 2.97 m resolution - esker ridges, drumlins, rocky knobs, shorelines and stream channels are in the data itself
• Anti-tiling terrain shaders - every layer blends three texture sizes by viewing distance, so no repeating patterns
• Cliffs without stretching - textures are projected from the side on steep faces, so cliffs show real rock texture instead of vertical streaks; flat ground is unchanged
• Verify - compares every terrain height with the original pixels

​

✦ PERFORMANCE

• Native 3840 x 2160 - the demo scenes are made for native 4K in all three pipelines, pixel error 3 on every terrain

​

✦ DEMO CONTROLS

Mouse look · WASD move · Shift fast · G walk at 1.8 m eye height · F fly · N / P next / previous level · H help

​

✦ UNITY 2022.3 AND ABOVE

Built-in, URP and HDRP in one package. Tools > Lidar Terrains > Project Setup switches on terrain holes in your pipeline asset with one click. The Built-in Render Pipeline has no post-processing, so the Built-in demo levels look simpler than the URP and HDRP ones.

​

✦ USE CASES

Open-world games · flight and driving simulators · hiking and survival games · cinematics · terrain studies. The heightmaps also work in other tools: 16-bit PNG, north up, size and height range in the file name.
