Research On New Methods Of Field Control Measurement Of 1:10,000 Aerial Survey In Plateau Area

With the development of economic society,Yunnan province to speed up the basic geographic information products production speed.Among them,the aerial field control is the first step of basic geographic information product manufacturing processes,aerial field control results directly influences the precision of the precision of other relevant process operation in the industry,aerial field control progress also directly affect the progress of other processes in the industry.Because of yunnan province is located in the plateau,latitude,near the tropic of cancer with large elevation difference,the characteristics of low latitude area,has been the basis of mapping control of the province are measured using conventional GPS operation mode,since this mode of operation by the joint measurement tedious and time-consuming restrictions on viewing distance of the base station,the job complex scheduling,mapping has become increasingly unsuited to the production under the new situation.In recent years,with the rapid development of GPS technology,for aerial measurement field controller also emerged a number of technical methods,such as the precise point positioning technology,CORS system(Network RTK)technology,long baseline solver technology.In view of this,the paper in addition to using conventional GPS static operation methods,will be mainly for three new methods of applied research,and four kinds of aerial field controller measuring method is applied to Wenshan 1:10,000 aerial measurement field controller by applying several methods,and the results obtained were analyzed.The paper topic in exploring research on the method of field control,can find a kind of high efficient and fast method,can quickly and good good basic surveying and mapping task,at the same time also to reduce the labor intensity of field staff.This study has important significance for the province-based GIS data production and updating.In the long run,can improve operating methods related fields of project units and Yunnan Provincial Bureau of Surveying and Mapping and the formation of the corresponding technical requirements standardized production jobs or work instructions,as well as professional and technical personnel to enhance skills,improve work efficiency,reduce production costs are an important constructive.
