The Local and Global Confidence Uncertainty Plumes of SAKWeb©

João Garrott Marques Negreiros, Marco Painho, Manuel Aguilar, Fernando Aguilar

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


SAKWeb© (Spatial Autocorrelation and Kriging Web) is the first Internet geosoftware that provides access to a wider audience to boost spatial analysis knowledge in conjunction with new tools (Negreiros, 2004). Under this geoweb solution, it is possible to create a local and a global uncertainty plumes after any Ordinary Kriging interpolation. To highlight and to compare both approaches using the same spatial contamination dataset becomes, thus, the core of this poster. It is expected that these accomplishments might be used by Geographic Information Systems (GIS) users with risk assessment troubles to layout a first raw global and local confidence plume.
