Some kind of map viewer
 

I recently attempted installing the Lighthouse mod, as well as the Kiel canal mod.

Following this I found that none of the light houses show up, nor any of the cities of the Kiel canal.

I checked and rechecked my Terrain CFG file to see if whether or not the location numbers were in sync, and found that they indeed are.

I was wondering if there was some kind of map viewer to see the actual locations of structers on the game map.

On the other hand, the program that allowed the placement of these add on objects.

Yes, the mission builder.
