A New Model of Economic Census Based on Geographic Space:A Case Study of the Fifth National Economic Census of Guangzhou
In order to carry out economic census scientifically and efficiently,and improve the utilization scope of census results,a new model of economic census based on geographic space was proposed.GIS,big data,cloud computing and other technologies were used to integrate multiple sources of geo-information data in Guangzhou,pro-viding detailed,complete and accurate economic census geo-information base map services covering the whole city.At the same time,based on an efficient and accurate address matching engine,the census objects were transformed from list form to precise geospatial data with spatiotemporal location information down to buildings,providing geospa-tial data statistical results for various stages of census work such as division of census areas,building plotting,unit inventory,census registration,and result summary in the city.This research provides some new solutions for the re-search and application of subsequent census results.
