Analysis on the Positioning Error of Mobile Phone Map in Agriculture Information Construction
摘要
Abstract
In view of the spatial position error in the application of mobile phone CAS to agriculture informatizaiion, the sources and magnitude of the errore were determined and measured through qualitative and quantitative analysis. It was concluded that the errors mainly come from the mobile phone positioning and coordinate conversion, and the mobile phone positioning is the major source; within a small scale, the error can be controlled within 5 m after reasonable data processing, which meets the requirements of agricultural informatization for precision. According to the sources and magnitude of errors, some suggestions and methods were proposed to reduce the error and improve the application precision, so as to provide references for the application of mobile phone CAS and accelerate the process of agricultural informatizalion.关键词
