Geologic maps are products of complex analyses and interpretations, and as such, contain a certain amount of uncertainty. Unfortunately, it is difficult to estimate the uncertainty within a geologic map. Much of this difficulty is due to the lack of a clear framework for describing the sources of uncertainty within the map and poor awareness, within the mapping community, of methods capable of ...

The study area is located in the state of Minas Gerais, Brazil, among the municipalities of Pedro Leopoldo, Matozinhos, and Sete Lagoas, with Velhas River as the eastern boundary. It is located in the São Francisco Craton, where carbonated argillo-arenaceous sediments are emplaced giving origin to the Bambuí Group, in the São Francisco Basin. Despite the geological knowledge previously develope...

Introduction Geologic mapping of planetary surfaces provides information on the nature, sequence, and distribution of material units, from which one can assemble a geologic history [1]. With this goal in mind, the Galileo SSI camera acquired an important dataset of images of Europa at a resolution suitable for geologic reconnaissance and mapping. We performed mapping and analysis of pole-to-pol...

Piton de la Fournaise (PdF) is a basaltic volcano whose activity characterized by effusive to mildly explosive eruptions. The geologic record preserves evidence of eruptions associated with the seaward sliding steep east flank. Such formed calderas that are several km in diameter and their products have been emplaced as breccias. breccias PdF offer opportunity sample wide range different lithol...

This paper outlines a new program of the British Columhia Geological Surbey Branch in the field of applied surficial geology. Its oh.jectivcs are to develop methodologies whereby informatiw from about 2000 existing surficial geology maps, in conjunction with subsurface data, can he used to produce derivative products in applied fields such as aggre@xte resource\. neological hazards, waste dispo...

Semantic Web technologies bring innovative ideas to computer applications in geoscience. As an essential part of the Semantic Web, ontologies are increasingly discussed in the geoscience community, in which geologic time scale is one of the topics that have received the most discussion and practices. This paper aims to carry out a review of the recent progress on geologic time ontologies, discu...

Abstract The landslide was recognized as the most common geologic hazard around world. assessment of relationship conditioning factors is a critical step in managing hazards and risks. Several models have been made to develop model recent years. Artificial Neural Networks (ANN) used this study identify important factors. Eight factors, including elevation, slope, aspect, curvature, lithology, s...

This paper describes a method and a system for visualizing a virtual tunnel through an existing geologic formation and a method for the generation of a camera animation along the tunnel axis. The tunnel is built from geologic data coming from vertical sample drills from the mountain top along the selected tunnel axis. Its wire frame model is then edited by a geologist and image information of t...
