I have surveyed a land about km square with complected details(roads, streets, buildings, T-Walls, Manholes, Corners etc) but with no traverse extension at the first, now when i have completed it and reached to the first area I was starting from and measuring with the data come from extension of change points in the site show me the errors in horizontal distance, EX: measuring the corner of a building which was measured at the first too, give me the error of 10cm-even 90cm
any suggestion and salvation way well be welcomed,
this area have surveyed by lieca TS11
it's worth mention that for salvation the problem i have measured all change points 3 times again by to TS06 and TS11, but there come different between them from 5cm to 60cm even with high accuracy doing the work!!!
as you see the picture this is the same point measured 3 times!
