Least square adjustment in surveying

NettetWhen you complete your survey loop, you observe or are given a misclosure value. Even if you close at 0.00/0.00 you still can have some kind of standard bust value because of the imperfections of instrumentation. This misclosure value is 2-dimensional, either X (departure/Easting) and Y (latitude/Northing) for horizontal distances or Z ... http://www.mygeodesy.id.au/documents/Chapter%202.pdf
