Wow. Roba thats freaking ingenious. I don't suppose you could reveal the technique you used to make that grid?

Thanks.

Probably the "wrong way"

I used a voronoi plugin in Gimp to generate regular diamonds, then stretched them out horizontally by eye until they lined up with he main features.

Try the following:
1. create a square grid.
2. rotate it by 45 degrees
3. Scale it vertically by 0.577 (or 57.7%)

That will give you a precise isometric grid.
