The gentle Acadian plain of Gloucester and Kent counties in north-eastern New Brunswick, Canada - winding rivers in steep ravines, wide raised bogs and rolling wooded hills - at their real size, at 1.23 m resolution

45 heightmaps of Gloucester and Kent counties in north-eastern New Brunswick, Canada from real-world elevation data (DEM). The low Acadian plain of north-eastern New Brunswick: winding rivers in steep sandstone ravines, wide raised peat bogs with pools and gently rolling wooded hills. Each map covers 9.997 x 9.997 km (about 10 x 10 km, 100 square km) at 1.23 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

• 45 heightmaps - 16-bit PNG, 8129 x 8129 px, relief from 51 m to 220 m per map
• 2 x 2 Unity terrains per map - 4097 samples each at the map's own 1.23 m spacing (one heightmap cut into 4 tiles that share their edge pixels); the unused 64-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: Meandering Ravine, Bog Lake, Valley Ridges
• Terrain Builder - one click turns any heightmap into a real-scale Unity terrain
• New Brunswick Acadian Plain ground look - 8 ground layers in 4K (meadow, forest floor, dry earth, scree, rock, gravel, bog, lake bed)
• Shore water - transparent winding rivers, bog pools and ponds: clear at the shoreline, the bed visible in the shallows, darker water further out, rivers that follow the valley downhill, a thin moving shore film and wet ground just above the water, in Built-in, URP and HDRP
• Forest floor, fields and bogs - the ground of the demo levels is painted from the real shape of each map: forest floor on the slopes, fields on the valley floors, bare rock only on real walls, bogs on the wet flats

​

✦ FEATURES

• Exact scale - size and height range are in every file name and inside every PNG, and the builder reads them for you
• 1.23 m resolution - river bluffs, terraces, gullies, stream channels, field edges and shorelines 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 walls 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 - no upscaling, demo scenes in player builds: HDRP 150-169 FPS · URP 144-155 FPS · Built-in 283-352 FPS (RTX 3090)

​

✦ 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, and Shore Water Setup the depth and opaque textures the water reads, 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, fishing 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.
