RESUMO

The aim of the present work is to develop, to implement and to test a geostatistics package for SPRING (Georeferenced Information Processing System). Kriging techniques, which are derived FRom Matheron s theory on regionalized variables (Matheron, 1971), are the conceptual basis for the geostatistics package. It comprises a set of integrated tools that can potentially enchance interpolation procedures due to its estimation character and the accuracy information provided by its inference model. GSLIB (Deutsh and Joumel, 1992), a geostatistics library, was used to develop the necessary algorithms. A case study was performed with soil samples collected in the Canchim farm, in São Carlos, SP. Kriging interpolation was applied over the samples to generate continuous images of day content in the soil. Results indicated a reasonable fit of the kriging techniques to the case study. A comparative analysis of kriging and other interpolation methods available in SPRING is also presented.
