Uso de Imágenes SPOT para el Monitoreo Ambiental y Determinación de Procesos Costeros

Abstract

Use of modem techniques like remote sensinq and satellite images, is nowadays without doubt one of the main factors to take a forward step towards the achievement of serious plans regarding Coastal Management and everything related to it, like determination oí sensitive arcas due to strong marine action and other factors which are the main causes of dynamic processes like erosion and sedimentation. Identification of these arcas is crucial for this kind of management plans because according to their sensibility, important decisions are nade, also creation of laws and regulations related to proper use oí coastal arcas, recuperation and protection plans, etc. A multi-temporal analysis of the land-use using three SPOT images (20 m) of different years (1986, 1992, 1997) by supervised classification in a specific area of the Colombian Caribbean Coast located between 10°06' ano 10°18' h.1 and 750281 and 75°42' W, including Pta. Barú, was done and focused mainly on environmental impacts caused by anthropogenic activities like deforestation of mangroves due to shrimp farming. Selection oí sensitive arcas, percentage of destroyed mangroves, arcas severely affected by sedimentation and its causes are part of this study.
