It seems like you if you had this, you could do some really interesting things with multi-scale collapse. For example, you could first use collapse to lay out biomes (e.g. beach needs to border sea, desert needs to border mountains, etc.) and then use those as constraints for the next scale level, which decides the details within those biomes, and the next level for cities and towns within those environments, etc.
