- Professional Surveyors-
-
- This is not a professional surveying system, nor will it pretend to be one. It
- is a preliminary survey. For folks who are land shopping or contemplating a
- sale, that's all they need. And rural property around here (backwoods
- Kentucky) is so worthless that most isn't worth surveying right. It's either
- survey it yourself, or nothing at all. And you oughta take a look at some of
- the land descriptions!! When they need a professional job done, I hope that by
- surveying it themselves they have made your job easier. If not, then I'd be
- interested to know the reason why.
-
- You might consider this method as your reconnaissance. It is so quick and
- simple that even your office personnel can gather useful information. I
- suggest that you keep a Silva Ranger in every vehicle. The Silva Ranger is
- available in quadrants for those who use that system. I have found quadrants
- to be much more prone to blunder than the standard azimuth system.
-
- If your present software makes a big production out of reducing preliminary
- surveys, then look at CAVEMAP1.BAS. You might find the data format a bit
- unusual, or you might like it. If you think that there is hope, I'll customize
- the program for you. It's just a whole lot easier if you make the tool fit the
- operator than if you try to make the operator fit the tool.
-
- The error of this method is about 1 per 100. That's right, 1%! Yes, I know
- that if your crew brings back anything worse than 1 per 3000, then they
- resurvey it on their own time. That's fine, when you need that precision. For
- a preliminary survey, you don't.
-
- This method was devised to survey caves. And I mean wet, muddy, crawling
- caves. I prefer data with 1% error to no data with 0.001% error. I wouldn't
- take a transit into a cave if you were to give it to me.
-
- I'm an analytical chemist, not a surveyor. I would appreciate feedback from
- professional surveyors.
