Control networks
Controlling two or three dimensions Networking is the main operation in the topography of the large or small areas. Control networks include a number of items or positions that are spatially arranged for the purposes of the control of additional points surveying or dimensional control on the jobsite. Technical Data used in the field explained in civil surveyor course in Rawalpindi.
The process followed by the removal of a surface to carry out the collection and processing of matter Data and the subsequent production of a plan or map, a brief description. The first and most obvious step is the purpose and nature of the project to know for the surveys are required to evaluate the accuracy specifications, the type of equipment needed and surveying involved processes. Some more details of civil surveyor course in Rawalpindi are as under For example, a major project requiring structures, etc. to sub centi metre accuracy are specified, in which case control studies with even greater precision is required. Earthworks volumes of the final plans are estimated therefore contours at intervals of 2 meters or less have to be returned. If a measure is adopted in plant 1/500, and then precision tracing represent 0.5mm 0.25 m above the ground, which improves the accuracy of the final process of the additional control and measurement implies better control to a higher accuracy. The location of the topographic data, GPS satellites are carried out with total station, or, depending on the size of the area, aerial photogrammetry. The cost of a photogrammetric survey is closely associated with the desired contour interval and the degree of die Flaeche. Therefore, the accuracy of the control network to define the quality of equipment and the necessary Number Of observations.
The duration of the project will affect the design of the study of the control points necessary centers. A project of limited duration, only a plug long and require solid wood, well-oriented company, reliable ground and surrounded by a small amount of cement. A thin spot on the top defines the geo metricalposition are. The next step is a detailed overview of the area around the best to establish Positions for control points. First Data will have from all sources, before you will be tested in the field. This data includes existing maps and plans, aerial photographs and data from previous measurements of the area. to ensure that the lines of sight between the control points are well above the ground and are therefore drawn free of brightness or by refraction effects longitudinal sections of the contours of the map.
