Territorial Information System and
Spatial Data Infraestructure of Asturias

Three digital models made from the LIDAR information available for the Principality of Asturias within the PNOA-LIDAR (National Cartographic System) have been incorporated as operational layers in the IDEAS General Cartographic Viewer.

Specifically, the added models are:

- Digital Slope Model, generated from the Digital Terrain Model

- Digital Relief Shading Model generated from the Digital Surface Model (represents the relief of surface elements such as buildings, vegetation, infrastructures, etc.)

- Digital Relief Shading Model generated from the Digital Terrain Model and that represents the relief of the topographic surface of the terrain (without surface elements).
