cations the text of the explanatory notes that accompany a set of two maps co-published in 1999 by the Commission for the Geological Map of the World and ANDRA entitled: Maps of the World Environment during the last two Climatic Extremes (1. The Last Glacial Maximum — ca 18,000 ± 2,000 yrs B.P., 2. The Holocene Optimum — ca 8,000 ± 1,000 yrs B.P.). A reduced version of these two maps, originall...

In 2010–2012, the hydrogeological model (HM) of Latvia (LAMO) was developed by the scientists of Riga Technical University (RTU). LAMO comprises geological and hydrogeological data provided by the Latvian Environment, Geology and Meteorology Centre (LEGMC) for the active groundwater zone of Latvia. In 2013–2015, LAMO was notably upgraded. The number of HM layers and the density of hydrographica...

The image of geologist is often associated with a “tough natural scientist” operating in the field without technology. This has changed with the large diffusion of information and communication technology; today, geologists face the digital world. The geological maps and cross sections have been fundamental for synthesizing the geological knowledge of a region, but GIS, 3D digital modelers, and...

With the three-dimensional (3D) geological information system development, 3D cross-sections (GCs) have become primary data for work and scientific research. Throughout past surveys or research works, a lot of two-dimensional (2D) cross-section maps been accumulated, which struggle to meet application needs visual expression, analysis, many other aspects. Therefore, this paper proposes an autom...

The aim of this study is to cross-verify of multiple logistic model at Korea using a Geographic Information System (GIS). Landslide locations were identified in the 3 study areas from interpretation of aerial photographs and satellite image, field surveys, and maps of the topography, soil type, forest cover and land cover were constructed to spatial data-sets. The factors that influence landsli...
