1. Krigagem com deriva externa aplicada à avaliação de recursos minerais de calcário e de minério laterítico / Kriging witch external drift applied to evaluation of mineral resources of limestone and lateritic ore
This dissertation is a work on applied geostatistics to evaluation of mineral resources. This application can be considered as the last step to such the task. The basic concepts are based on current geostatistics, with extensive use of informatics resources. The first goal of this work was to test the technique named kriging with external drift in the evalua

2. Estimativa da vulnerabilidade de aqüíferos utilizando sistemas de informação geográfica e geoestatística-UGRHI-PCJ / Aquifer vulnerabilty assessment using geographic information system and geoestatistics - UGRHI-PCJ
The natural aquifer vulnerability estimative is one of the primary tasks to be accomplished for a groundwater planning, control and prevention program, that would for example aim a protection perimeter design for human use or environmental protection. In this study the GOD model (G from groundwater confinement; O from overlay strata; D from depth to groundwa

3. Variabilidade espacial da qualidade físico-hídrica do solo de um sistema em produção agroecológica. / Spatial variability of physical - hydric soil quality of an agroecological production system
The knowledge of physical hydric soil quality indicators is crucial during planning and management of agriculture activities. Many articles had been written to identify and to correlate the physical hydric soil quality and crop production. However, the most part of the results are not reliable for mapping spatial variability, mainly in large areas. The objec

4. Estimativa das funções de recuperação de reservas minerais usando copulas / Estimation of recovers function of mineral reserves using copulas
The aim of this thesis was to develop the applied methodology of copulas in the problem of conditional reserves estimation. The copulas have a different approach from sequential gaussian simulation and in this thesis was used to correct the tonnage and ore quantity of a mining project. It is presented a theoretical summary that is the bases to the study of c

5. Development implementation and test of the geoestatistics procedures (kriging)for the SPRING (georeferenced information processing system) / Desenvolvimento, implementação e teste de procedimentos geoestatísticos (Krigeagem) no sistema de processamento de informações georreferenciadas (SPRING)
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 p
