New Brunswick Miramichi Rivers & Bogs Real-World Terrains 10 km

• Heightmaps - 48 x 16-bit greyscale PNG, 8129 x 8129 px: 48 maps of 9.997 x 9.997 km (about 10 x 10 km, 100 square km) at 1.23 m per pixel
• Relief - 56 m to 410 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 0.2 cm on the flattest map and about 1.3 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 winding river valleys, low plateaus, lakes and wide peat bogs of the Miramichi country in eastern New Brunswick, Canada, at their real size, at 1.23 m resolution

48 heightmaps of Northumberland County (the Miramichi country) in eastern New Brunswick, Canada from real-world elevation data (DEM). Winding rivers in wooded valleys, the low plateau of eastern New Brunswick with its lakes, and wide flat peat bogs with streams and pools. 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

• 48 heightmaps - 16-bit PNG, 8129 x 8129 px, relief from 56 m to 410 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: River Valley, Plateau Lake, Bog Plain
• 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 winding rivers, plateau lakes and bog pools: 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 182-188 FPS · URP 167-181 FPS · Built-in 319-350 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.
