Abstract
The definition of the investigation area border line, the choice of the optimal sampling mesh and exploration technique, the proper analysis of the collected data, represent the most important steps during an environmental research project. The “Krige Diagram” demonstrates that the evaluation results depend on the accuracy by with each of these phases has been performed. This paper introduces an innovative geostatistics-based technique for environmental data analisys and evaluation, called “Kriging Assistant” (KA). This new technique, developed within the Department of GeoEngineering and Environmental Technologies – University of Cagliari (Italy), is able to work both in 2D and 3D dimensions and, especially, can fit the experimental semivariogram curve through an innovative procedure that is no longer based on the evaluator experience but on an automatic modeling routine.
