The non-point source (NPS) information system based on remote sensing and GIS and its preliminary application

  • Yunpeng Wang


A non-point source information system (NPSIS) has been constructed by use of remote sensing and GIS technology, and a construction method of NPSIS introduced with Shenzhen as an example. With the remote sensing land-using images as an environment unit, the analysis modules based on NPSIS are built through combining the NPS model with NPSIS, and the preliminary NPS calculation and analysis performed.
