Blank Slate: Empty Flat Test Map

A terrain generator for a completely blank test map: one flat island at 5 m, a gentle coast and open sea on every side. No hills, rivers, lakes, trees or rocks.

Endorsed by flat earthers everywhere: no curvature, no hills, and you can sail right up to the edge. We checked, and the ships did not fall off.

Features

• Flat island: a rounded square plateau covering most of the map, perfectly level for laying track and roads anywhere.
• Sea on all sides: a short coastal slope down to 30 m deep water, so ships work all the way round.
• Nothing on it: no trees, rocks or forests, and no reforestation.
• Every climate: shows up as "Blank Slate (flat island)" in the generator list for Temperate, Dry, Tropical and Subarctic.

How to get a map with no towns or industries

1. Main menu: Map Editor, then start a new map with your climate.
2. Open Generate heightmap, choose Blank Slate (flat island) and generate. The editor does not place towns or industries.
3. Save the map, then start a game from it with Play Map.

Notes

• Choosing Blank Slate from the normal New Game menu also works, but the game still places towns and industries there.
• The island is stretched with the map, so on 1:2 and 1:3 maps it is a long rectangle.
• Only used when generating a map. It does not change existing saves and is safe to add or remove at any time.
