High Arctic coast at its real size - 43 maps of fjords, sea cliffs and frozen bays from the Queen Elizabeth Islands, Nunavut

Fjord walls rising from cold sounds, ice caps that end in cliffs above the sea, fjord heads choked with summer sea ice, and coastal lowlands cut by braided streams. Every map is a 16.26 x 16.26 km square of real coast (264 km²) from LiDAR elevation data at 2 m per pixel, with 271 m to 1,331 m of relief, built in Unity sample for sample.

​

✦ ON THE COAST

• 43 coastal heightmaps - 16-bit PNG, 8129 x 8129 px; size and height range are written in each file name and inside the PNG
• True-scale terrains - each map becomes 2 x 2 Unity terrains of 4097 samples, made from the original pixels, 1 unit = 1 metre
• Three coastal demo levels - Ice Cap Coast, Mountain Fjord and Fjord Head, each ready in Built-in, URP and HDRP (9 scenes)
• Frozen bays and open fjords - summer sea ice with melt ponds painted where the bays are frozen; Shore Water where Mountain Fjord is open
• Terrain Builder - turns any of the 43 heightmaps into its own real-scale terrain with one click

​

✦ A COASTAL GROUND LOOK

• Eight 4K layers - frost-shattered coast gravel, lichen crust, tidal silt, shale talus, bedded cliff rock, beach shingle, late snow and sea ice
• Read from the shape of the coast - slope finds the cliffs and their talus, height above the sea finds the tidal flats and raised beaches, drainage finds the stream beds
• Cliff beds - each demo map carries its own bed table, so sea cliffs show soft bands of sedimentary colour
• No repeats, no seams - hex-tile sampling at three scales and broad colour variation on top, from a walker's eye up to a full flight

​

✦ FRAME RATES AT 4K

• 3840 x 2160, no upscaling - HDRP 115-128 FPS · URP 98-139 FPS · Built-in 155-278 FPS in player builds on an RTX 3090

​

✦ SET UP IN A MINUTE

Unity 2022.3 and above. Tools > Lidar Terrains > Project Setup turns on terrain holes for your pipeline; Shore Water Setup switches on what the water needs. Built-in has no post-processing, so its demo levels look plainer than URP and HDRP.

​

✦ MADE FOR

Polar expedition and survival games, sailing and flight simulators, open-world coastlines, cinematics and terrain research. The PNGs also open in any tool that reads 16-bit heightmaps.
