Spatial Analysis for Groundwater Pollution based on Monitoring Data by COMGIS

Groundwater pollution is an important issue in recent years, in order to know how the spatial pollutant situation is, the visualization analysis is adopted to analyse the regional pollution with monitoring data. Monitoring data can be easily acquired, which is the basis for spatial analysis, with the GIS software, the vector layer of monitoring data can be established, and environmental pollution monitoring data can be dynamically managed by point vector layer. On the development platform VB.NET, taking geographic information system components (COMGIS) to design and develop software to come true the spatial analysis function, with the design techniques, various space interpolation methods can be loaded to realize the spatial analysis, such as IDW, Krige, Spline, Trend. These methods can be used to acquire the data of unknown pollutant region by loading the monitoring data layer. With the spatial interpolation method, visual spatial analysis function for groundwater pollution can be realized easily with monitoring data.
