Great news.
You're right I forgot about the rotation. One of the differences between Geographic and UTM is that the vertical axis is the true north using Geographic mode vs grid north using UTM mode. The exact rotation from true north to UTM grid north is found in the Cave data frame (bottow left) in the box Meridian, but I think the rotation tool as steps of 1 degree. So you might have to adjust parts of your drawings after dragging them back in there new location.

Hi Mark,

Switching from Geographic to UTM is as simple as clicking on the UTM icon next to Geographic icon in the Calculate tab... This said, if you have done some Plan drawings while using Geographic "projection", you won't see them anymore when zooming onto your displayed data. There are not gone, but all your Plan drawings will found around X=0, Y=0 as the cave ref point in Geographic "projection" is X=0, Y=0... far away from your cave ref point in UTM coordinates.
To bring your drawings to the correct UTM location, first under Drawings tab, enable the Grid display. You should now see the UTM grid and coordinates under the Elements tab. Zoom out until you have both X=0,Y=0 (where your Geographic drawings live) and your cave data displayed in the UTM projection on the same screen. Select all the drawing elements at once and drag them toward the UTM cave ref point. Zoom in and drag them again, closer to your data.... Do it again and again, until you can drag them to overlay nicely your survey data.

This would be the same "issue" if you decide to switch the depth ref Entrance/Sea level.

Great! Thanks.

Nope, doesn't seem to work. A message says no image is available for this area.

Jochen might be able to fix this issue.

I also had an error message when I tried to import CRP generated *.kml files into QGIS and this was caused by slight format issue. *.kml files output by CRP don't follow exactly the structure/format of a *.kml file generated by Google Earth. However, the generated *.kml files are readable by Google Earth, so a way around to correct any format issues is to open the file in Google Earth and save/overwrite the file from there. Then the format glitches should be corrected and you should have no issues importing your files in third part software/apps.

LRDUs = GDHB in French

then Vizualization > Google Earth > save to *.kml

If you select LRDUs + Volume before exporting to kml, then you should get something similar, the difference with VT being the polygones are not filled.

same kind of issue here but it's not as bad as total freezing and PC reboot. When I go to OpenTopoMap view, it takes some times to get the cave displayed (with graphical scale and OTM license comments) but no OTM tiles are uploaded. Then CRP seems to freeze, but if I click on Plan view, after a while, CRP actually goes to Plan view. So CRP doesn't seem to be completely frozen at this stage. However, CRP gets sluggish as hell and pretty much nothing can be done at this point but to close and relaunch CRP.

Ok, thanks for the heads-up. I'll le them know.

Prima!

OK, will let my friends know :). Thanks.

great! looking forward to it! :)

great thanks!

Got an email from Marco, shot/splay notes will be added to topodroid regular csv export with next release.

Got a couple of email exchange with Marco,

Re: Therion import : looks like the only difference between *.th from TD and from Therion is the very first line i.e.: "encoding utf-8".
As adding this line to a *.th file issued by TD, seems to make CRP happy on import, he's going to add that first line to the *.th export

Re csv import : at the moment, the only way to get the Notes (=splay/shot comments) from TD in the csv format is to export the raw data as well (tick box on export). But CRP doesn't seems to like the extra raw data. I have suggested to add the notes within the default export. will see what he says.

At the moment, the only way I have found to get the Notes imported in CRP is to use *.tro format.

1) I have tried importing Therion files straight out from TopoDroid as the Notes written in TD are not exported in *.csv file.
I suppose if several softwares use the csv format as import format, it might be more complicated for me to ask Marco Corvi to make such a change.

2) Done
