Hello Therion 5.3.5 ubuntu 10.04 In the attached file the following information is given about the survey title: RhinoPassage length: 189.07m (surface 0.00m, duplicated 24.58m) vertical range: 20.51m (from 1.27@RhinoPassage at 20.38m to 1.3@RhinoPassage at -0.13m) north-south range: 92.47m (from 1.27@RhinoPassage at 33.43m to 1.53@RhinoPassage at -59.04m) east-west range: 66.67m (from 1.53@RhinoPassage at 66.67m to 1.0@RhinoPassage at 0.00m) number of shots: 281 number of stations: 282 The duplicate figure got me wondering, it seems to be counting the splays but the length does not. As the duplicate none splays are only about 10m. Maybe this is what is wanted, but I personally think that the duplicate value should be the amount taken off the length by the duplicate flag? Ie why is length treated differently to duplicate (something to do with the way survex treated splays and duplicate as different, I think that splays are not included in extend in survex) Maybe 2 figures would be better, duplicate length and duplicate splays. {probably best to ignore this next bit} Oh this leads to all sorts of thinks that are really not important, like maybe giving the length of all the splays, and the number of stations, is it really 282 or really 54. All depends on your definition I guess Andrew
