[Therion] scrap without stations keeps the original sketch in Topodroid

[alastair gott]

Hi Omri,

You cannot have a scrap without any survey points in it. each scrap or th2 file needs 2 or greater survey stations in it to function correctly without warping the image.

extended elevations are a bit different (and sometimes need careful adjustment of the legs to fold the extended elevation in the correct way).

[Caviat, I know you can have a th2 file with no survey stations in it, but we're not creating rocks today wookware.org/surveys/therion/testrocks].


Regards,
Alastair Gott.

Subject: [Therion] scrap without stations keeps the original sketch in Topodroid

Hi all,
I want to raise a question I've been having with my self...
when I'm in the cave I use Topodroid to make the sketch. when I export the map in Therion with "debug on" I see the changes that Therion makes which make the final map different from the sketch I made in Topodroid (sometimes it is a big difference).
a few days ago I noticed that if I make a new scrap and move all the map elements that I draw except the stations, the map turns out exactly as I draw it on Topodroid.

As I understand it, Therion change the map to overcome or compensate errors or Deviations, especially when there are loops involved, but wouldn't it be more accurate to stick to the original sketch that I drew with Topodroid  in the cave?
what do you think?
