Flow of operation of the estate outside shallow analyse GPS
From;    Author:Stand originally

1. net form plans to reach period of time to arrange:
Of program of GPS net form and reference point distributing about, to make the dot of whole web form in the error is worth can even, best net form can depend on the distributinging program of reference point:
(Of 1) planar reference point distributing:
Net form measures an area: Had better at least 3 foregone reference point distributing 4 quadrant that measuring area periphery, if foregone triangle is nodded (reference point) be located in measure an area outside, the predestined relationship outside measuring an area and this bit more foregone distance had better not exceed 20km.
Linear measure an area: Had better at least 3 foregone reference point distributing to be reached in the end that measures an area in the center of, and left and right sides of every other 30km had better have a foregone reference point.
(Of reference point of 2) tall Cheng distributing:
Meshy measure an area: Generally speaking, need to 4 foregone levels are nodded inside every 10km*10km limits as reference point, and distributing at measuring an area all round. If be about to get taller tall Cheng precision when, but at measuring the number that reference point of close level tall Cheng increases inside the area, wait for normally measure dot and apart of foregone level dot to had better not exceed 5km.
Linear measure an area: Had better at least 4 foregone reference point distributing to be reached in the end that measures an area in the center of. When linear when the area that measure an area is larger, need to foregone level is nodded inside every 10km*10km limits as reference point.
The arrangement of period of time is best can keep away from midday (AM11:00~PM1:00) observation of period of time. After period of time is arranged, fill in watch of plan period of time, clear directive gauger measures station journey before.
2. places station order:
Estate chief should lose a bright assure to know to place station staff outside its place decoration measures sign of site name, drop and switch machine time, if wear station staff to have not clear item, also answer to understand actively to chief ask for instructions. Put forward erect GPS this note and operating sequence with reminding means mainly below:
(1) seeks a site:
If already was had been to,should nod, should not produce a problem; If had not gone nodding, and press a point write down the person that search, in reach a point later the mark stone number that should confirm this to nod, check nucleus is not had by accident hind go again erect instrument. The reference point of Taiwan tall iron has planar reference point and tall Cheng reference point (horizontal filling dot) cent, two apart are very close (normally planar reference point is located in building top, and tall Cheng reference point is located in on this building floor) accordingly look fallibility admits. And the acknowledge with the due personnel that place a station is tall Cheng reference point it is protuberant round head steel hammer; And planar reference point is planar and crossed silk. If still have doubt, board this question record at hand book, avoid to cause inside the big mistake on computation of course of study.
