I am reading the data in from a file named map.txt for the map outline and then using the data in types.txt for ambiguous tiles. You can see the outline file here and the type file here.

To view your own map, enter data in the same format as the map.txt file for the map outline, then enter data for the land types in the same format as types.txt, and then click generate map. (1 always stands for land and 0 stands for water) You can also use the online map generator.
