It is hoped that this implementation will be used by users with problems to layout risk analysis environmental maps and plumes assessment. Spatial analysis, Moran I and other uncertainty measures are also reviewed.10538183engGISKrigingLocal confidenceLocal varianceMoran IPlumes assessmentSAKWebSpatial analysisVariogramManagement Information SystemsGeneral Computer Scienceconference object10.2495/RISK080091https://www.scopus.com/pages/publications/58849119174
