For small topographic survey
jobs with less than 500 side shots, I do the following process:
1. download from
topcon ts via topcon link
2. export raw file
to csv (hor,dist,ver,rr,etc)
3. open the csv in
excel and use a preprogrammed spreadsheet to compute coordinates, elevs
coordinate file to csv
5. import in autocad
6. connect the dots.
I am comfortable
with this process. Problem is lately, office have to process survey data from
several crews with different TS. Each surveyor has his old habits in coding
features, station naming, etc. even though there are set standards. One guy
would use all caps, another would use all small caps, another would use dash
(T-1), another would use dots (T.1) etc. Some of these differences are also due
to Total Station brands.
is now beginning to feel the glut in data processing. We have to combine all
survey data from the different crews and adjust the traverse loop before doing
the side shot processing.
There must be a
better way to process huge amounts of data. A typical large topographic survey
work has around 50,000-75,000 points.
