Hi I have a question about "cavedepth" and propbably need some help as I can't figure out the problem. My complete survey is about underwater cave passages. Therfore I have an option inside every survey and centerline which is "calibrate depth 0 -1". All survey are with "data diving station depth left right up down newline tape compass". And every depth is with positive numbers like 5.3 then which means -5.3m of waterdepth. Lowest number all over all surveys is 0.0. Biggest number is 24.1. Every scrap contains all the survey stations within this part of the cave as a "point station". So in the end I have every surveyed station inside the scraps. When I print the map as a pdf file (with all the scraps) I don't get the right number for Depth. With numbers as above I would expect a cave depth of 24m but I get 22m. Of course I can do an override with "\cavedepth{24\thinspace{}m}". But this is not what I want to. So can anyone explain please why I don't get the correct number for cavedepth in the map header? Thanks! cheers, Torsten
