The changes are usually in one place for a single hierarchy (MAPINDEX), but I have started using multiple hierarchies that require duplicate but not quite identical submaps. I am using a tree like structure similar to that (single hierarchy) described on the Mulu pages http://www.mulucaves.org/wordpress/surveying/the-mulu-survey-dataset (but using therion of course). My first hierarchy (MAPINDEX) is for map outputs - these have passages offset where on is above the other. Second hierarchy (MAPINDEX)is for atlas outputs - these use duplicate submaps that do not have offsets (hence my request a while back for a new feature -offsets off, which would avoid the need for this hierarchy) Third hierarchy (MAPINDEX)is for another more detailed atlas output of a particularly complex part of the cave. It mostly uses the same submaps, and always the same scraps, but some submaps are broken up more finely or in different places. Forth hierarchy (MAPINDEX) is for an atlas/map output based around chronology of exploration, rather than geographical location. All of the submaps tend to be different to the above, but as always the same scraps are used. This is reasonably straight forward for a single cave (one level on the hierarchy) but becomes unwieldy for multiple caves and on multiple levels of the hierarchy. Adequately structured, but difficult to remember to update each submap and MAPINDEX as the extent of surveyed and drawn cave grows. As you can guess, keeping the map title under control is the least of my difficulties. I am chasing my therion mantra of 'one input once - many outputs' a bit too hard perhaps (although multiple hierarchies is contrary to that I admit). If I was a bit more clever I could probably condense the first three hierarchies into one, but hierarchies based on other than physical location will always be separate until therion develops a bit more I think.
