[Therion] How to get the right count for cave lengths

>(I also switched to using a new centreline when the team changes - this is a pain though, because it means any calibration, copyright, date, authorship, etc. also has to be repeated. It would be so much easier for it to respect group.)

 

It is a pain, but it is something I have got used to. 

Repeating from memory my interpretation of something that I think Stacho or Martin B posted some years ago; the reporting of statistics is only resolved down to centreline resolution (not survey leg resolution).  So this means that Therion might well be honouring any changes to metadata that you make using group - endgroup.  But the statistics gathering code cannot report accurately those changes, because the lowest resolution is 'by centreline'.  If this interpretation is correct, then group endgroup is good for settings that affect the centreline shape, flags, standard deviation, but not for metadata that needs to be gathered for statistics reporting, such as changes relating to team members.

 

Regarding reporting of surface survey statistics, you can export a sql database, and I am sure that it will contain the information you want, subject to the 'centreline resolution' issue above.  You will need to think of the query criteria to set to get the result you are after.  That is perhaps not completely helpful, because it means you will need to manually enter that information in the map-header, either by customising it, or entering it as a map-comment.

 

'Statistics' is a layout option, so it is possible that the visibility of surface centrelines may affect the statistics reported.  I don't think so, but it is something you should check.  ie

symbol-show group surface-centreline vs symbol-hide group surface-centreline

 

Otherwise, the next best option is as you have requested, an option to include or exclude the surface survey in the explo-length and topo-length totals for team members.

Maybe a new statistics option is desirable;

statistics <explo/topo-length on/off>, with the default [off] matching the current behaviour.

 

If such a change were contemplated, then I would like carto'-length' (or maybe better carto'-scrap') to be included in the statistics that can be sorted by team member 'contribution' sorting.  ie, I would like to sort cartographers by the amount of drawing they have contributed (currently only alphabetically is possible).  I think the best measure of this would be the number of scraps they have drawn (consistent with my contention that more little scraps is better than few large scraps).

And I guess the same potentially applies to copyrights.  If there are 50 scraps that are copyrighted to one organisation, and 4 scraps to another, there should be the ability to sort the larger one first, rather than alphabetically.  ie expand

statistics <explo/topo-length                               on/hide/off> to

statistics <explo/topo-length/carto/copyright on/hide/off> with the last two ranked on scrap count.
