I built the map by stacking images on top of each other in MS Powerpoint. [I have used Powerpoint for designing technical posters and this was similar to a poster.] I use Gimp to modify the images and then add them to the Powerpoint "poster". I am open to other free software (I do the maps as a hobby) but I don't want a large learning curve. Any suggestions?

The trouble I have is that the objects (especially terrain) comes in squares which lends itself to blockyness. Also, since I'm stacking objects on top of each other there is not really a smooth transition between water and land. Is there some way to modify images so that I get multiple textures in one "square" with an irregular edge defining the point where the textures meet?

Thanks.
