Hi Martin I think we each lost each others meaning in translation.
"Maps do not need to be children of the surveys they are based on, but the way Topparser currently creates them they are. Therion does allow them to be outside of the 'survey' 'endsurvey' block, and indeed outside of the survey.th file altogether." I agree it is a 'feature'. Therion allows maps to be tied to the hierarchy of the surveys and it also allows maps to be completely independent of the survey hierarchy, but it depends on how one constructs the dataset. Despite wanting to for a year or two, I have not yet got around to constructing an 'independent' dataset, so I'm hardly an authority - just repeating what I read in the Therion Book and the wiki. I'm confused by the case you describe below - having 2 nearby caves each with a name 'map1' would be a problem if one used maps that were defined independently. But surely they would sensibly be named CaveAMap and CaveBMap? The reason I like the idea of independent map structures is that, when for example Cave A and Cave B are large cave systems with 2 or 3 levels of nested surveys each, and the distant reaches of these two caves that started out far part are now close together, and one wants a map that consists only of the last 300m of each cave where they are close together. With maps dependant on surveys you need Select submapA at subsurveyA.surveyA Select submapB at subsurveyB.surveyB With maps independent on surveys you only need Select submapA Select submapB The benefits are greater (if I am correct) the more nested levels (I have not yet had to go beyond three) and the more surveys and indeed the more caves that are converging. There is a similar (but partially opposite) effect on the 'station-names' suffixes required when drawing scraps. Now I am rambling. _____ From: therion-bounces at speleo.sk [mailto:[email protected]] On Behalf Of Martin Sluka Sent: Monday, 29 July 2013 8:07 p.m. To: List for Therion users Subject: Re: [Therion] Topparser response Jul 29, 2013 v 9:48 AM, Bruce <bruce at tomo.co.nz>: and indeed outside of the <http://survey.th/> survey.th file altogether. It prevent mistake in case: map1 in one system and map1 in another system map1 at surveyA is different from map1 at surveyB It is feature not bug!!! m. -------------- next part -------------- An HTML attachment was scrubbed...
