Hi, I'm a teacher looking to create a map on which my students can recreate their town - Sidney, NY - in Minecraft. My research has shown that I need to start with a greyscale heightmap to put into a program called Worldpainter. I tried to do it, but it's a bit beyond my capabilities. It will be used by a group of students in an afterschool program. You can contact me at jgray@sidneycsd.org. Thanks.
