Triumph LS confidence story

I am sure we can all attest to these type of results.
On my 2 most recent surveys I have adjoined another surveyor in my area. We have a good relationship and share information such as maps, legal documents, general knowledge, coordinates etc.
I had to tie into some of his traverse and located monuments considerably off site to retrace and reset a corner that he had established. I localized on 2 points to search for more of his points using his coordinates and easily found his traverse point that I was looking for.
Over the phone I would tell him what I measured with the L.S. between his points and he would tell me his inverse values. The differences were as if I had used a total station with the largest difference - .04'
On the other survey we were trying to verify whether certain monuments were in the same place that he had measured years ago. (He and I didn't have a map to refer to) These markers were in the woods .
Again the differences were all within .07'
He was very impressed.
Agreeing with others total station work like this in heavy woods and canopy
is a YUUUGE confidence booster!!

Thanks for sharing that Sean. Not only will the LS get as good of results, but on extremely long lines through the woods and over severe terrain changes I 100% believe it will get better results! No matter how tight any traverse is closed, there is still some traverse error. With the LS, the maximum is going to be 0.05' per/point, but most times it's more like 0.02' per/point. Most other surveyors in my area simply do not believe what/where GPS can be used now and how accurate it is and that's fine by me :)

I agree Darren. Most surveyors are not ready to use GPS the way we do/are,
and I feel the same way, using GPS is better than traversing because the error is confined to the point being measured, not the whole group of points being measured from a traverse with a closing error.
I believe that the work I do now is much better and more thorough than before. The overall survey measurements are better, I tie into distant offsite points with an eye toward future surveys and as another check or to gain a better understanding of existing conditions on the current survey.
With the time and effort saved by using the L.S. in other front end phases of the survey, (not traversing, limited line cutting, huge time savings in recon and measuring)
I can do a better job at the back end by marking the lines better for the client which is much easier to do now with the L.S.
Good Stuff!!
