Several threads in the Maps and Graphics Forum contain years of tireless work by dedicated posters aimed at creating the perfect OTL reference- and basemaps, both for their own sake and to assist the creation of realistic alternate histories.

There are several series of OTL maps based off different colour schemes, using techniques and standards depending which one had the preference of the map-makers, and while still largely compatibles, having each their specificities.

Maps and patches are classified separatly, along which basemap was used:

• Revised Worlda Maps - The original basemap, posted by Diamond. The most used on board, for historical as allohistorical maps.

• QBAM Map Series by various people

• Qazaq's UberBAMs(or Qazaq's UberBAM)-

• Europe Maps by Valdemar II -

• Europe WWII Map Series by Morgan Hauser, Chris S, and others -

• HRE Map Series by Thande, Boto von Ageduch and Alex Richards -

See also Lord Sander's Map Repository for more Worlda maps, and the Blank Map Directory.
