Cartografía de los movimientos de ladera de la cuenca de Loja y generación de base de datos con aplicación de herramientas SIG. Polígono 4

Abstract

Abstract: The mapping of landslides is carried out in the Loja basin, in polygon 4, its main objective is to generate a database with the application of GIS tools for slope movements until 2019; For which a photointerpretation is made with orthophotos from 2010, belonging to the GIS Lands and digitization of the polygon of the hillside movement in ArcGIS 10.3 Subsequently, a field validation is carried out using the inventory sheets proposed by the Andean Multinational Project: Geosciences for the Andean communities PMA-GCA in 2007. Thus, 155 landslides classified per their typology have been inventoried: 101 flows, 44 creeps, 9 translational landslides, and 1 rotational landslide. This information was entered a geodatabase in ArcGIS to have relevant information regarding slope movements until 2019 so that the information can be constantly updated and incorporate necessary attributes to the spatial units to analyze and manage the evolution of hillside movements, as well as executing actions in a timely manner in the areas considered affected by said landslides.
