FTPro - Random World Mapping for Fun and (no) Profit

[Master TMO]

The next step is checking to make sure I filled in all the holes in the continental shelves correctly. If I leave a spot below sea level and under water, Fill Basins will not fill the hole, rivers will run there instead of to the coast, incise flow will carve the erosion paths in that direction, etc. Now, there are occasions where we *want* that to happen. Death Valley lies below sea level. The Mediterranean Sea could theoretically be closed off at the Gibraltar Straits and be a below-sea level basin.

I can check this by running the Find Rivers command, I can look at the river paths and look for low points, where the rivers do not run toward the coast like they should. One of the things to keep in mind with FTPro when it runs rivers is that it runs them to the waterline by the lowest possible path. That lowest possible path may require water to run uphill. At this point, we don't really care about that. We're just making sure everything reaches the coastline properly.

This is the river view:


We can see one major area of concern on the eastern continent, which I've marked off in the box. Zooming in, we see:


There are a couple of spots that I missed raising the land masses above the shelf limit. By pulling the water line back up to regular sea level, I can see if it's a natural valley I may want to retain or not. In this case, the areas are completely underwater, and I don't care:


So I filled them in, checked the rest of the map, and called it good. Here's the fixed version:
