It is the first principle of Surveying. Initially main control points are established with very high accuracy at the far distances to cover whole the area and then using these points as the reference points you establish the secondary and tertiary control points.

Surveying camp (civil engineering) aims
Hi,
If you are a Civil Engineering student then in most of the curriculums Surveying camp is introduced after you study the plane and geodetic surveying. Generally it is divided in two parts in two different semesters like in HPTU(Himachal Pradesh Technical University) and HPTSB(Himachal Pradesh Takniki Shiksha Board) for diploma course in the same. You have the knowledge of the basic objective of surveying which is to prepare a map or plan.
In survey camp you will be given an area of which you have to prepare a topographical map. You have the knowledge of various instruments like chain, compass, level, Theodolite, tachometer and plane table etc. Now all you have to do is to take these instruments according to their need and you have to progress towards your goal.
At the start you have to take care of the basic principles of surveying, like working from whole to parts, tells you to first set the control points with very much precision.
You have to use Theodolite, Tachometer etc. to locate these precise points, with respect to the nearest available Benchmark(B.M.) and it will be okay to draw these points on the sheet. Always keep your field notebook with you to note down the field measurements.
Now you are ready to locate the interior details of the area.You have to pour in all the knowledge of your studies in camp to create a topographical map. You will be needing almost all the minor to major instruments here.
You must know the contouring to prepare the contours on the sheet. Plotting contours is again a matter of practice and knowledge. Knowing all the important signs is important for you, because these are used in the map or plan that you will prepare.
If you have any suggestions please write on.
Thank you for reading.
