Really you where able to do a lookup ... man that is odd. As for the "missing" tiles ... that's mostlikely due to the fact when I created the map I was given the chance to remove areas of the grid that weren't needed ... the ocean and unpopulated mountain regions and such.
As I stated in a prior post ... I was able to do a look up on with the map that you included with the app but it didn't work for mine ... It's odd you get it to work NP ... hmmmm ???
IS there a tutorial for the 7ane geodat tool?
