In this research the results from using digital ortho-photography, altimetric data of sensor, field works and Geographic Information Systems at the littoral of the department of Atlantico (between western tajamar of Magdalena river and Puerto Velero) and the Barú peninsula (department of Bolívar) are shown for the establishment and mapping of the units and geomorphological features. The basic procedures included geo-referencing of old aerial photographs of the Instituto Geográfico Agustín Codazzi, photo-interpretation and identification of the different units and geo-morphological features, digital terrain model generation, comparisons between old photographs and present ortho-photographs (2005) and verification works and taking of complementary information in situ. At the study zone of the department of Atlantic 11 geo-morphological units (9 associated to low beaches and 2 to high beaches) were identified; while at the Barú zone 9 units (5 associated to low beaches and 4 to high beaches) were identified. The results show, first of all, the spatial usefulness and accuracy of these two remote sensing sources and of the high resolution Digital Terrain Models in the geo-morphological coastal analysis, as well as, the potential of the spatial functions of the Geographic Information Systems as technical tools for the understanding of the coastal landscape and its composition within an administration, control and preservation framework of these environments.Downloads
