Using perlin noise to create a procedural island for a tile-based game. My map is stored in a 2d array, with each tile having a type (deep water, shallow water, beach, grass, forest, hill, mountain).
What would be the most efficient way to go through my map, after it's generated, and smooth out the edges of the terrain? Using a tileset, we run into issues with a 1x1 tile that sticks out by itself.
