Using GIS for data visualization and processing in pollution sources census

Pollution sources census will provide data for the macro-control of environmental protection and management and promote economy structure adjustment and planning. Data visualization and processing for pollution sources census is practically meaningful for improving the pollution sources census digitalization and intelligence management level. Based on GIS and spatial database, an information management system for pollution sources census has been developed. It has some functions such as data visualization, data query, data statistics and spatial analysis. Combined with the characteristics of environmental management, the system can provide efficient technical support and scientific basis for environment protection, total quantity control of pollution sources emissions, pollution sources management and economic structure optimization, et al. The experiment results show that it has a certain value and significance for census data exploration and application.
