Abstract:
Based on the analysis and reference of traditional change detection methods,this paper proposed a change detection model based on grid-based clustering and spatial overlay,realized a rapid change detection in the national geographic condition census data,expanded the theory and method of vector spatial data change detection,provided theoretical and methodological support for national geographic conditions monitoring.
