Very nice - I particularly like the coloured boxes map selection interface. Thats a bit like our CWBP Ansium map in the wiki and they both work real well.

Just out of curiosity, do you have height maps for all the regional tiles too ? I remember you saying once you made it with the help of some 3D - bryce right ? Because were playing with these world renderers at the mo and if you have the height then you could put it in those too.
