The relief has a major impact on the landscape`s hydrological, geomorphological and biological processes. Many geographic information systems used elevation data as the primary data for analysis, modeling, etc. A digital elevation model (DEM) is a modern ... see more

GPS, digital photogrammetry and laser scanning techniques have been applied and compared in the frame of the studies of two complex landslides located in the Emilia-Romagna Region (Northern Italy). The three approaches, characterized by different accuraci... see more

Geomorphometry is the science of quantitative description of land surface morphology by the mean of geomorphic indices extracted from Digital Elevation Models (DEMs). The analysis of these indices is the first and most common procedure performed in severa... see more

Digital Elevation Model (DEM) validation is often carried out by comparing thedata with a set of ground control points. However, the quality of a DEM can also beconsidered in terms of shape realism. Beyond visual analysis, it can be verified thatphysical ... see more

This study examines the spatial distribution of the organic carbon found in alluvial soils affected by successive floods. In flood zones, very little is known of the processes associated with the development of soils subjected to frequent flooding, in par... see more

Dams are structures built for controlling the flow of water for many useful purposes such as water supply, power generation, retention of mining and industrial waste, as well as recreation and flood control. However, they bring together some risk of dam b... see more

Today Chile has no elevation model (DEM) with national character. Analyzed from the point of view of science and geomatics technologies, a DEM and the orthoimages may be updated in their respective scales 1:25,000 and 1:50,000, these are essential for nat... see more

The tectonic condition of Gorontalo, which is located in the north of Sulawesi Island has implications for the spread of geothermal potential. The area in Gorontalo with the largest geothermal potential is the Suwawa area, Bone Bolango Regency. Therefore,... see more
