GPS topographic mapping.pet gps tracker cat Solution

　　In the past, when surveying topographic maps, it was generally necessary to first establish root control points in the survey area, and then put Total station or Theodolite on the root control points to coordinate with small flat plate mapping. Now, it has developed to use Total station and electronic notebook to coordinate with ground object coding in the field, use large-scale mapping software to carry out mapping, and even develop to the nearest field electronic flat plate mapping, which requires surveying the surrounding landform and other minor points on the survey station, These sub points are all visible to the measuring station, and generally require at least 2-3 people to operate. Once the accuracy does not meet the requirements during the jigsaw puzzle, it is necessary to go back to the field for measurement. When using RTK, only one person needs to carry the instrument on their back to stay at the sub point of the terrain to be measured for one or two seconds, and input the feature code at the same time. Through the manual, the accuracy of the point can be known in real time. After measuring an area, they can return to the indoor area, By using a professional software interface, the required topographic maps can be output, which requires only one person to operate with RTK and does not require inter point visibility, greatly improving work efficiency. By using RTK in conjunction with an electronic manual, various topographic maps can be measured, such as ordinary maps, railway line strip topographic maps, highway pipeline topographic maps. With a bathymeter, it can be used to measure reservoir topographic maps, navigation ocean maps, and so on.
