| Abstract: | The original plane reference frame of ChengDu city is introduced firstly,and its limits are analyzed also.Then,the project using GPS technology to establish C-order GPS control network is introduced in detail,and the scheme of control points layout,data processing and precision analysis etc.are studied emphatically.Then,by surveying C-order GPS points combined with some original control points,the consistency of GPS and original control network is testified.By the project,we can conclude that the C-order GPS control network can not only meet the demand of urban expanding,but also inherit the consistency with the historical data. |
