Integrated Collection Of Internal And External Component Census Technology And Application

At present,with continuous development of “digital urban management”,the census and renewal of urban components are becoming bottlenecks for system construction.Besides,acquisition and updating of basic data are difficult links during system construction.While tradition collection mode of urban components is unable to satisfy current demands of economic and social development due to much manpower and complex procedures.Based on the characteristics of traditional component collection,this thesis analyzes the link occupying a mass of manpower,focuses on application of Beidou satellite navigation technology,introduces high-precision geographic information collection device,establishes independent CORS system,innovates workflow and realizes integrated collection of internal and external component census,all of which greatly save manpower and increase working efficiency.Furthermore,product quality is more stable than traditional collection method,and achieved good economic and social benefits.
