Cartografía de los movimientos de ladera en el sector NW de la cuenca de Loja y generación de base de datos con aplicación de herramientas SIG. POLIGONO 1 .

Abstract

Abstract:Carried out in the north-west area of ​​the Loja basin, resulting in an inventory of hillside movements, the methodology used begins with the previous photointerpretation of orfotos and aerial photographs added to the subsequent cartographic field verification, In addition, field records were used for an orderly and systematic survey with the main characteristics of landslide movements such as movement activity, lithology, type of movement, morphometry, causes and triggers, land cover and use, among other. With the help of ArcMap, the creation and digitalization of the movements was carried out. slopes mapped in the field in order to obtain the database. In which, we obtained as result 82 movements classified in falls, crawls, flows, landslides rotational and translational landslides, each of these with their respective characteristics that involve an affected area of ​​108.4 ha. The creation of this database data is to have a record of the geographical location of the movements of slopes, in order to prevent and intervene in the affected areas in an efficient and timely manner.
