地理国情监测中异形图斑的处理方法

The processing method of special-shaped pattern spots in the monitoring of geographical conditions

针对2021年地理国情监测项目生产中地理国情监测地表覆盖数据与“三调”地类图斑数据的叠加所产生的大量尖锐、狭长异形图斑,提出了异形图斑问题检测与处理相结合的自动化处理方法,建立自动化处理流程并开发了处理工具,并在山东省地理国情监测任务中进行了应用,自动综合处理效率达94.5%,极大地提高了生产效率。

For the large number of sharp,narrow and other special-shaped pattern spots generated by the fusion of the land cover data of geographical conditions monitoring and the third land survey,an automatic processing method combining the detection and processing of special-shaped pattern spots was proposed,a processing tool was developed and applied in the geographical condition monitoring task of Shandong Province,the efficiency of automatic comprehensive treatment was 94.5%,which greatly improved the production efficiency.
