Dataset description
The coastline represents the linear segment that runs along the margin of the Andalusian coast in contact with the sea, from its inception in Portugal to its eastern end in Murcia. To obtain it, four digitisation criteria have been used that define the coastline from a geomorphological perspective with a clear intentionality applied: 1) Last wet mark of the tide in sedimentary coastal formations exposed to the open sea (beaches). 2) Lower tide limit (among all available orthods) for estuaries and tidal net. 3) External limit of infrastructures for all types of infrastructures in direct contact with the sea. 4) Base of cliffs for rock formations connected directly to the sea. The coastline is characterised physiographically, thematically and in its magnitude. A double delineation of the coastline is included; one of great length that crosses marshes, estuaries and limits of ports and spikes and another shorter, in which marshes, estuaries and infrastructure have been avoided, giving rise to a line of length more in line with the statistical value that is usually handled. A series of derived layers have been extracted from the long layer that differentiates, on the one hand, the hierarchy established in the classification of the physiographic units (Level 1, Level 2, Level 3 and Level 4), and on the other, the different themes of interest from the physiological point of view and the impact on the route of the coastline (cantiletes, dunes, margins of estuaries and tidal pipes, urban and beaches). Also included are traces associated with different toponymic sources of each coastal section and other useful layers for cartographic design.

The coastline is characterised physiographically, thematically and in its magnitude.
A double delineation of the coastline is included;
one of great length that crosses marshes, estuaries and limits of ports and spikes and another shorter, in which marshes, estuaries and infrastructure have been avoided, giving rise to a line of length more in line with the statistical value that is usually handled.
A series of derived layers have been extracted from the long layer that differentiates, on the one hand, the hierarchy established in the classification of the physiographic units (Level 1, Level 2, Level 3 and Level 4), and on the other, the different themes of interest from the physiological point of view and the impact on the route of the coastline (cantiletes, dunes, margins of estuaries and tidal pipes, urban and beaches).
Also included are traces associated with different toponymic sources of each coastal section and other useful layers for cartographic design.
