Spatial analysis of water quality using a combination of GIS and statistical software

0
GIS-based spatial analysis was combined with statistical analysis to process time varying water quality data. A data model was employed to manage the spatio-temporal data. The spatial data engine of ArcSDE was used to access the database. A data relationship model was developed to perform data communication between GIS and the statistical software. Visual Basic was used to construct links between all the software packages being implemented. This allows the combination of the spatial and temporal characteristics into the water quality mathematical analysis. Ten water quality parameters were selected from a water quality monitoring programme to validate the present approach.
