Applied Research On Surveying Technology Of Rural Homestead Usufruct In The Key Area Of Guangxi

Confirmation,registration of rural homestead and collective construction land rights,which is urgent,difficult and costly,is one of main daily business of land resources department.GPS and GIS technology is an important technical means in land resource management in our country,and it is widely used in land and resources survey because of its advantage of high precision,high efficiency and powerful graphics processing and spatial analysis capabilities of GIS.GPS and GIS technology is also an important technical means in the confirmation,registration of rural homestead and collective construction land rights.In order to improve the work efficiency and the accuracy,save cost and time,in this paper,Guigang is used as an example to discuss the application of advanced mapping technology such as GPS and GIS in the registration of rural homestead and collective construction land rights.The work of rural homestead survey is to obtain the rural homestead information such as location,area,attribute and spatial relationship between the homesteads.The choice of technical methods has a direct influence on the quality,precision and measurement efficiency of the rural homestead,and further is related to the scientificity and accuracy of management.the purpose of this paper is to discuss the application of GPS and normal surveying technology in cadastral surveying,and the application of GIS in database construction taking Guigang as an example.Method employed is empirical analysis based on Guigang.The result is that in order to improve the work efficiency and the accuracy,GPS is used in the control surveying stage and the normal technology is used in cadastral surveying stage;when database construction,GIS is the main tool.It is concluded that: in the case of one wide measuring region but scattered spots,comprehensive application of multiple technologies is the most appropriate method of rural homestead survey.Comprehensive application of multiple technologies can improve work efficiency and achievement accuracy at the same time.
