REDIAM. WMS Digital Model of Visual Boundaries - Horizons. Andalusia Visibility System
Description
Node of the Andalusian Environmental Information Network. Regional Government of Andalusia. Web service of the Map of Visual Limits Horizons integrated within the line of work of the Visibility System of Andalusia (SVA). The VAS contains the data and procedures necessary to model the actual or potential visual relationships between the different locations of the territory, up to a distance called - maximum visibility - established in 15 km; the result is a collection of visual parameters defined for more than 11 million observation points distributed homogeneously throughout the Andalusian territory. Among them is the parameter called 'visual horizons', which calculates at each observation point which are the last (farthest from the observer) points of each group of visible points. These points precisely delimit the different perceptible visual planes, generating the visual structure of the territory. The Digital Visual Boundary Model, with a resolution of 20m, contains information about the frequency (for how many observation points) with which each point in the territory is 'horizon'. The most frequent points are organized in rows that usually coincide with the -cordales- of the relief. This model does not depend on the distribution of observers over the territory, and can therefore be considered as a physical property intrinsic to the geometry of the land. Node of the Andalusian Environmental Information Network. Regional Government of Andalusia. Integrated in the Spatial Data Infrastructure of Andalusia, following the guidelines of the Cartographic System of Andalusia.
