估计GIS中面要素定位误差的精度指标

Accuracy Indicators for Estimating Positional Error of Area Primitives in GIS

    摘要
  • 摘要: 在文献1,2基础上,进一步论述了由GIS中点、线定位不确定性所引起的面要素定位误差,同时给出了估计面要素定位误差与面域面积的精度指标。

     

    Abstract: On the basis Of papers1,2,the positional errors of area primitives in GIS are discussed in this paper.And accuracy indicators for estimating positional error of area primitives and area of uncertainty region are also given.These are of some value to both further researches and industrial production.
