Aiming at the problem which the technical system of multi-scale spatial data linkage updating is imperfect,this paper puts forward a technical system for multi-scale spatial data linkage updating.The technical system is based on pattern recognition theory and takes"updating information detection-adaptive incremental updating-updating information multi-scale matching and transmission"as the main line,which realizes the deep integration of pattern recognition technology and multi-scale spatial data linkage update application and can provide important technical support and guarantee for the rapid updating of spatial data.The experimental results in Zengcheng district,guangzhou shows that the method proposed in this paper is very effective for multi-scale spatial data linkage updating in complex urban areas.
