摘要：根据森林资源二类空间数据数字化的过程探讨其误差的来源,提出森林资源二类空间数据生产中质量控制和误差校正的方法。通过自动选取控制点和对控制点按图幅构造不规则三角网建立图面坐标与实际坐标的对应关系,对森林资源二类调查空间数据校正,提高森林资源二类调查空间数据的精度和校正效率。依据此方法对福建森林资源空间数据校正,消除了空间数据的整体误差。
According to the digitizing procedure of spatial data of forest resources by designing survey,the causes of spatial data error was analyzed in detail and some suggestions were put forward to guarantee the precision of spatial data. The methods of collecting control points and transforming the spatial data to rectify error were also introduced. By selecting control points of all data automatically and making the relationship between the coordination of map and actual coordination by construct triangular irregular network (TIN) for every standard map,the accuracy of data and the work efficiency of transforming was improved. This method had been adopted in the rectification of the spatial data of forest resources by designing survey in Fujian Province and achieved a reasonable result.
