China: The Ministry of Environmental Protection is using GIS to reduce pollutant discharge in China. Ministry staff members are using ESRI’s ArcGIS software to manage, inventory, and analyse nearly 10,000 pollutant discharge points within the country. Data collection for such a large scope was a challenge faced by GIS project managers when planning the project.
With ArcGIS in place, they can integrate GIS and the department’s automated monitoring system as a method for quickly accessing environmental data. GIS supports comparative spatial analysis for conducting side-byside comparisons of different provinces and different cities.
The implementation of ArcGIS makes it possible for the ministry’s system users to create data layers of pollution sources, real-time data, pollutant amount counts, and other relevant data. They can integrate projects and run trend analyses. The ministry has also deployed ArcGIS Server so that the data can be accessed enterprise-wide.
