Here is a map of my fictional world Al'Dor that my friends and I are creating for our own D&D campaigns.

Map of Al'Dor
I tried using MashupForge, but it only lets me display one layer at a time.

I have been using GIMP to create layers for changing political boundaries (our world is 1600 years old and things change a lot) which works pretty well as I turn layers on and off, but I can't share it like that.

Does anyone know of a way I can make my map an interactive map and host it online (so a user can turn layers on and off and zoom in and things) I know some basic html and java but i'm not sure how I would go about making this.
