I dont know if its even possible to make for Civ V, but i would be eternal grateful for having such a tool. 
I know Denniz made the one for Civ IV so hopefully he thinks of making one for Civ V also

What does MapFinder do?
When you start a game of Civilization, sometimes the initial position given to you is less than desireable. For example, you could be surrounded by tundra, limited resources, no river, etc. Typically the cure for this is to press the 'Esc' key and click on 'Regenerate Map'. Once or twice isn't bad, but multiple times can be tiresome, especially if you're looking for a specific type of starting position. What Map Finder does is allows you to automate the regeneration function of the game. Using Map Finder you can tell the program to look for specific types of maps that include settings you want in your game. Once those settings are chosen and you set Map Finder to start searching, it will continually regnerate maps and any map that meets the certain conditions you've specified are saved and stored for you later to look through.
For example, you could specify you want a fish, three hills (for production), two other food resources, and a river. Map Finder will keep regenerating and examine each map to see if it fits the above conditions. If it does, than that map is saved.
Map Finder is allowed for HOF use. It does not give you any additional information and merely allows you to quickly locate desired starting positions. Map Finder is optional and may, or may not be used at your choice.
Map Finder was designed and coded by HOF co-admin Denniz.
