Hi I would question the conversion of splays to LRUD. They were probably introduced because that was the best that could be done in a reasonable time frame while surveying underground. Now splays are taking over. They give more and better targeted information. LRUD always had major flaws like whether to take it perpendicular or as a perpendicular to the bisector of the previous and next leg (so what happens if there are 3 legs from a station) And junctions where always a real mess, then there are pitches, lots of times the readings where left blank.
Maybe converting LRUD to splays is the way to go, but that would give splays that go through rock at times. I would see them as 2 types of data, would you convert dive data to normal data, possibly to move from one program to another? I personally would leave them as splays, hopefully software will catch up to allow models to be produced from the better data Andrew On 18/07/13 21:28, Martin Sluka wrote: > Footleg, > > I apologise myself, but try to read something about geodetic method > tachymetry :) > > http://engineeringsurvey.blogspot.cz/2013/02/tachymetry.html > > Splay shots allow to survey cave and not only to paint it.
