LÍNEA DE COSTA Y SISTEMAS DE INFORMACIÓN GEOGRÁFICA: MODELO DE DATOS PARA LA CARACTERIZACIÓN Y CÁLCULO DE INDICADORES EN LA COSTA ANDALUZA

Coastline and geographical information systems: data model for the andalusian coast characterization and coastal indicators estimation The coastline is a key element for coastal planning and management, however, its digitalisation at fine scales requires a precise geometric delimitation and a rigorous criteria establishment for its definition. The criteria selection should be based on the work purpose and future applications. In this sense, Geographic Information System (GIS) techniques, spatial databases and an appropriate data model for the database design are key elements that enable establishing a work flow for coastlines digitalisation and subsequent analyses. This paper presents a methodology for the Andalusia coastline definition and positioning at fine scale (1:2.500) using specific criteria for the coastline digitalisation and a data model for the spatial database design. The digitalisation and data entry in the database were carried out through ortho-photos
