Tutorial - How to create a world using Real-World Height data

Ok.

1) In photoshop make sure the file is saved as 16-bit, do this by going to Image->Mode and choosing 16bit Grayscale.

2) Unfortunately this seems to happen to most user-created maps and any that I have created I just go over them with the 'smoothing' tool. It can get tedious with a large map. I might send an email to EA to query this problem as a few people have seen this happening.
