Question

Explain by numerical example why angular loop closures in very small lot boundary surveyors will be expected to be larger than the equivalent in a larger survey of the exterior of a 40 acre farm lot. 12. 13. Explain why determining the error estimate in a 700 ft. distance calculated by laying out a tape 7 times calculated differently than the standard deviation of a 100 ft. distance measured 7 times using the same tape? An old check of a blunder in a measured horizontal angle was measuring both the interior and exterior angles and comparing their sum relative to 360 degrees. In a modern world of data collectors connected to total stations why is that check of less relevance? what are the units of the least squares product (1/error estimate)" residuawhy are the units of this product independent of what measurement you are referring to? Note this is kind of a trick question. 14. 2 15,

Explanation / Answer

in an angular loop, in the very small plot, to cover the whole point you have to take more points compare to a larger survey. hence chances of error in the small plot are more. thence closures will be more in small plots.
