Real terrain data

What drives the game

Local land relief, water boundaries, represented ocean depth, grounding and collision use numeric elevation from Mapzen Terrain Tiles on AWS. Terrarium pixels are decoded into metres in the browser. Detailed tiles provide land relief and the water boundary; zoom 7 retains the source mosaic's negative NOAA ETOPO1 ocean elevations because detailed ocean tiles are flattened to the water surface. Ocean bathymetry is coarse, oversampled data. It is not a marine chart and is not suitable for navigation.

Limits

The source mosaic has different dates and resolutions. Most global land is around 30 metres at native resolution, while ETOPO1 ocean depth is about one arc-minute and may be oversampled in local views. Coastline seams, buildings and source voids can produce errors. Pancakes Boat adapts and shades the data for entertainment and makes no safety or accuracy warranty.
