VESPER 1.5 - spatial prediction software for precision agriculture.

Abstract

VESPER is a user-friendly software program, written at the ACPA, to calculate global and local variogram models, undertake global and local kriging in either punctual or block form and output the parameters and estimates in an ASCII text format. The program provides control of the semivariogram calculation and choice of models that may be fit to the input data. A boundary and prediction grid may be generated in the software or supplied as an external file. VEPSER allows user defined neighbourhood and prediction-block sizes, along with a number of more advanced controls. It provides a real-time graphical display of the semivariogram modeling and a map of the kriging estimation progress. Having the ability to tailor the prediction process to individual data sets is essential for Precision Agriculture (PA) where data quantity, density and measurement quality varies.
