Abstract
The paper deals with the development and application of the methodology
for automatic mapping of pollution/contamination data. General Regression
Neural Network (GRNN) is considered in detail and is proposed as
an efficient tool to solve this problem. The automatic tuning of
isotropic and an anisotropic GRNN model using cross-validation procedure
is presented. Results are compared with k-nearest-neighbours interpolation
algorithm using independent validation data set. Quality of mapping
is controlled by the analysis of raw data and the residuals using
variography. Maps of probabilities of exceeding a given decision
level and ?thick? isoline visualization of the uncertainties are
presented as examples of decision-oriented mapping. Real case study
is based on mapping of radioactively contaminated territories.
