- IDEC / lidar-territorial-v1r0-2008-2011
- Purpose
- The main objectives of this geoinformation are: 1- To obtain models of terrain elevations and surfaces, as well as realistic 3D visualizations of the territory. 2- Facilitating the calculation of flood risk and other risks where knowledge of the relief is essential. 3- To generate objective forestry metrics, to facilitate knowledge of the spatial distribution of tree cover. 4- To provide a reference base for the development of any activity that has a territorial impact and that must take into account the terrain. They are particularly relevant in the field of technical, management, planning or territory administration activities. 5- To carry out spatial analysis operations with other sets of geographic information, especially in 3D.

Domain consistency
- Name of measure
- Compliance with INSPIRE requirements (metadata)
- Evaluation method description
- The metadata is reviewed for compliance with the INSPIRE specifications, in accordance with the criteria defined in the current Technical Guides. The metadata is considered compliant if the only notices identified are related to the use of Catalan as the main language of the register, a language that is not included in the list of languages provided for in the INSPIRE directive.
Conformance result
- Statement
- The point cloud was captured with a LiDAR sensor, calibrated and adjusted with topographic control areas, in order to obtain an altimetric accuracy with a mean square error of about 6 cm in flat areas with little vegetation. The point cloud was subsequently automatically classified and, in addition, the terrain, high and low points, and power towers and lines were manually edited.
- Description
- Point cloud obtained with a lidar sensor.
