cavern: show total length of splays

[Beni]

Currently, cavern produces no info on the splay information. It would be good if cavern could output information about the total length of splay shots in the processed dataset, like:

n> total length of splay/duplicate shots = 726.21m

current output:

I tested and for me the total length shown does NOT include any of the sorts of splay legs:

olly@gemse:~/git/survex$ cat splaylength.svx 
*begin survey
*fix 1 0 0 0
1  2  1.00 000 00
2  .  10.00 090 00
2  .. 10.00 240 00
*begin
*flags splay
2  s  10.00 300 00
*end
*end survey

Survey contains 5 survey stations, joined by 4 legs.
There are 0 loops.
Total length of survey legs =    1.00m (   1.00m adjusted)
Total plan length of survey legs =    1.00m
Total vertical length of survey legs =    0.00m
Vertical range = 0.00m (from survey.s at 0.00m to survey.s at 0.00m)
North-South range = 10.00m (from survey.s at 6.00m to anonymous station at -4.00m)
East-West range = 18.66m (from anonymous station at 10.00m to survey.s at -8.66m)

Are you sure you're correctly flagging your splay legs?

If you think you are, can you provide an example to reproduce this?

Hi Olly,

thats not the problem here; i ask for an enhancement of the log output:

Currently, cavern produces no info on the splay information. It would be good if cavern could output information about the total length of splay shots in the processed dataset, like: n> total length of splay/duplicate shots = 726.21m

aka show how much splay/duplicate is contained in the data. Maybe it is also a good idea to explicitely differentiate between the two: "n> total length of splay=123.45m and duplicate=32.21m (total=155.66m)"

[Olly Betts]

Oh right, I was misled by your summary.

[Beni]

sorry :(

I checked and we don't currently track this.

I wonder if it's better to do via aven so we don't end up tracking a zillion different things here - people might reasonably also want plan and vertical for splays and duplicates, and adjusted for duplicates (and maybe splays - you can make a loop containing legs explicitly flagged splay!) That would also provide a way to get these stats for a sub-survey too.
