New Brunswick Kings & Saint John Hills Real-World Terrains 10 km

• Heightmaps - 21 x 16-bit greyscale PNG, 8129 x 8129 px: 21 maps of 9.997 x 9.997 km (about 10 x 10 km, 100 square km) at 1.23 m per pixel
• Relief - 138 m to 374 m per map (lowest point of each map at 0)
• Unity terrains - 2 x 2 terrains of 4097 samples per map, terrain holes for the exact edge
• Height precision - one height level is about 0.4 cm on the flattest map and about 1.1 cm on the map with the largest height range
• Demo content - 3 map prefabs of 2 x 2 terrains (one prefab works in every pipeline) + 9 demo scenes (3 per pipeline)
• Ground textures - 8 New Brunswick Lowlands ground layers + the shared ground layers, 4096 x 4096 albedo, normal and mask
• Water - transparent lake and river surfaces whose colour comes from the real water depth (depth texture), soft shorelines, travelling waves and river flow, for Built-in, URP and HDRP
• Shaders - anti-tiling, world-aligned terrain shaders with side projection on steep faces (triplanar) for Built-in, URP and HDRP
• Editor tools - Terrain Builder, Project Setup, New Brunswick Ground Textures; PDF documentation included
• Compatibility - Unity 2022.3 and above; Built-in, URP and HDRP

The rugged hills, lake chains, highland ponds and farm valleys of Kings and Saint John counties in southern New Brunswick, Canada, at their real size, at 1.23 m resolution

21 heightmaps of Kings and Saint John counties in southern New Brunswick, Canada from real-world elevation data (DEM). Rugged hills and ridges, chains of lakes in long valleys, ponds on the uplands and farm valleys of southern New Brunswick. 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

• 21 heightmaps - 16-bit PNG, 8129 x 8129 px, relief from 138 m to 374 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: Lake Chain, Rugged Hills, Highland Ponds
• Terrain Builder - one click turns any heightmap into a real-scale Unity terrain
• New Brunswick Lowlands ground look - 8 ground layers in 4K (meadow, forest floor, dry earth, scree, rock, gravel, bog, lake bed)
• Shore water - transparent lake chains, highland ponds and streams: 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 146-186 FPS · URP 132-194 FPS · Built-in 204-430 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.
