Abstract

Abstract: This article presents the glacial retreat that the Sierra Nevada de Santa Marta located in the Colombian Caribbean has been experiencing, due to the climatic changes experienced over time. Subsequently, the information was vectorized and stored in a spatial-temporal database built with the purpose of obtaining trajectories, visual snapshots of glacier extension, three-dimensional models and a estimated calculation of glacier retreat during the period from 1850 to 2021. Keywords: Glacier retreat, image classification, trajectories, space-temporal database, moving regions trajectories. Sin embargo, en el presente artículo se hace uso de una base de datos espaciotemporal con información vectorizada de la zona de estudio, con el propósito de obtener instantáneas visuales de extensión glaciar, modelos tridimensionales y así mismo un cálculo más preciso del factor de cambio del glaciar en el periodo comprendido entre los años 1850 y 2021.
