Set the canvas dimensions for a blank map. The map you have open stays in your library.
This map was made before shapes. Converting turns urban areas, water, landscape and territories into shapes that stay sharp at every zoom, and waterway labels into rivers. Territories are clipped to the coast.
How much ground one map pixel covers. The relief brush uses it to turn wavelengths in kilometres into map pixels. Relief already painted keeps its size on the map; only new strokes use the new scale.
A new map of the box, enlarged, with its coast, borders, rivers, roads and places. Your map stays as it is.
This area has relief that is not baked into the height, and the detail map will not include it. Bake first
Maps live in this browser. Opening a file or starting a new map adds it here rather than replacing the one you have open.
