About This File
Guamtopia: my first island region, and in two versions! This region was created with a USGS map of the U.S. Territory of Guam in the South Pacific. This is not an accurate scaled map of Guam. On the contrary, it is larger than the actual island, and I compressed the elevation variation greatly so that you can build all over it!
The overall map is BIG, but the actual land is not that large and I would say it is a medium sized region. You should be able to see in the pics yourself - just look at the city boarders which I left on. Most all tiles are large city tiles.
The versions: This is subtle, but basically one version makes a full rectangle by including many tiles that are nothing but water (this is my preference.) I imagined that many others would prefer to not have those wasted tiles, so I made a second version that is only tiles that have some land. You can see in the pics.
I hope you enjoy!
Dependencies:
You must have either SC4Mapper or SC4TerraFormer.
The first screenshot shows the map rendered with cycledogg's Columbus Terrain Mod with standard snowcapped file, and with the Realistic Water Mod - these, of course, are not necessary to play the map.
The second screenshot shows the without_water_tiles version of the map in its terraformer colors. The colors will change to normal in game colors when the tiles are opened.
