CentrED stands for Centralized Editing. It is a Client/Server based map editor for Ultima™ Online.
The intention behind this is, that the only available GodClient is rather old and was never really supported by any server emulator (at least not that I know), but I wanted the ability for several people to work on the terrain and statics together, without having to constantly transfer their current state....
MapTool is a command line utility offering several helper functions to process UO data files.
For example it can defragment indexed files (like art, gump and statics) and even generate empty maps.
