1. Dynamic anisotropy and non-linear geostatistics supporting short term modelling of structurally complex gold mineralization
Abstract Non-linear geostatistical methods are known to deal appropriately with the geological and geometrical complexity of gold deposits. This article reports the results related to an investigation to improve the gold content estimate based on restricted ore modeling to honor the structural aspects that control the mineralization. The grade domains are de

2. Indicator kriging applied to RMR geomechanical modelling in a Pb-Zn deposit case study
Abstract The opening of a mining enterprise requires knowledge of the geomechanical characteristics of the mineral deposit, which will be worked according to the use of parameters of stability and/or resistance of the material, as well as the discontinuities present in the rock. In this study, the Rock Mass Rating methodology was used to propose a geomechani

3. Geological modeling by an indicator kriging approach applied to a limestone deposit in Indiara city - Goiás
Abstract The mineral exploration activity consists of a set of successive stages that are interdependent on each other, in which the main goal is to discover and subsequently evaluate a mineral deposit for the feasibility of its extraction. This process involves setting the shape, dimensions and grades for eventual production. Geological modeling determines

4. Identifying forest ecosystem regions for agricultural use and conservation
ABSTRACT Balancing agricultural needs with the need to protect biodiverse environments presents a challenge to forestry management. An imbalance in resource production and ecosystem regulation often leads to degradation or deforestation such as when excessive cultivation damages forest biodiversity. Lack of information on geospatial biodiversity may hamper f

5. Geração de mapas multitemáticos em agricultura de precisão.
RESUMO: O objetivo deste trabalho foi delinear uma metodologia de geração de mapas multitemáticos para o apoio à tomada de decisão nas culturas de grãos, considerando a abordagem integrada e hierarquizada dos fatores que interferem na produtividade. A área foi mapeada para os atributos da fertilidade do solo, nutrição de plantas, plantas daninhas e

6. Estudos geoestatísticos aplicados à um depósito magmático de Ni-Cu / Geoestatiscal studies applied to a Ni-Cu magmatic deposit
The studied deposit is composed of a mafic-ultramafic suite with cupro-nickeliferous sulphide mineralization associates and has an extensive data base with information such as chemical analyses and density, and such as lithologic description on the borehole samples. This work presents the application of different geostatistics techniques with two distinct ai

7. Modelagem ambiental com tratamento de incertezas em sistemas de informação geográfica: o paradigma geoestatístico por indicação / Environmental modeling with uncertainty treatment in geographical information systems: the indicator geostatistical paradigm
The use of Geographic Information Systems (GIS)to model environmental phenomena limits decision-making processes because the products of GIS modeling, such as agriculture suitability and vulnerability to erosion maps or economic-ecological zoning, do not encompass quantitative information on data quality. Current GIS technology does not associate the notion
