Footleg >., but I thought it cleaned these up when you saved the file (or maybe it is when you open a new file or close PocketTopo). I have never noticed my PDA memory cards littered with back-up files. Just seen one instance on the card when PocketTopo is running. So on that basis I assumed that the auto-backup feature will only save you if PocketTopo crashes or the PDA was destroyed (or battery ran flat) while in the middle of surveying. Once you finish and close the project (or switch to a different file in PocketTopo which I often do on a trip when working on large projects with several areas active) then you lose any auto-backup of the file you were last working on. If it is not on the memory card and the PDA then gets damaged (in transit in the cave rather than while in active use) then you would lose the data if only stored on the PDA internal memory.
Yes, there are only two backup files, and they are both of the file currently or last worked on. We do end up with multiple files worked on in any one survey trip, so that is a flaw with working directly on the built in storage. Perhaps I should manually copy previous files to removable media as I create a new file! I use old slow cards (they are free and plentiful) so am reluctant to work off them directly - pockettopo is slow enough as it is with large datasets (yes I know there is a workaround - I just like to keep the workflow and data structure simple). >I am working on a system to organise data for a larger cave, mixing historical data and recent data. I'll try to document it once I have determined that it really works. I have spent much more time working out how best to do things than actually drawing anything yet, as I want to be sure I am doing it right before spending the next few years drawing! Fantastic, there is no hurry, as it is unlikely I will beat you to it. And in my previous post I forgot to finish one of the sentences. >Bruce's example also includes author and copyright options on the scraps. How does Therion use these? Or are they just allowed on the scrap options but not used in any generated output? For scraps, copyright information is displayed in pdf headers in the same way as surveyors and explorers (by default I think) and the author is reported as 'drawn by' in the same way. For survey centerlines, as far as I know there is no way to get therion to report the author, but as the Therion book says, the information is accepted. I think it should be included in the database export, but it seems to date that it is not. I notice in 5.3.11 the database export now includes some map information, so perhaps the centerline authors can be included soon :-) Bruce -------------- next part -------------- An HTML attachment was scrubbed...
