Surface model of Catalonia 1 m - 2021-2023
Regular grid model of 1 meter resolution, from all over Catalonia, which expresses the orthometric altitudes of the surface of the territory, including the natural and artificial elements found on the ground (trees, buildings, etc.).

- Purpose
- The main objectives of this geoinformation are: Carrying out urban and territorial planning studies, for the design and evaluation of the environmental and visual impact of infrastructures, calculating slopes, studying solar orientation, improving landscape design, etc.; Assessing natural risks such as floods, torrential rains, landslides and rockfalls; and providing information that contributes to promoting actions and projects to improve adaptive capacity in the face of the impacts of climate change; Studying erosion processes and identifying areas vulnerable to soil erosion, allowing the implementation of land conservation and restoration strategies; Optimizing the management of resources, such as irrigation water, in the field of precision agriculture; Providing a reference base for the development of any activity that has a territorial impact and that must take into account the relief. They are especially relevant in the field of technical activities, management, planning or administration of the territory; Perform spatial analysis operations with other sets of geographic information, especially in 3D.

- 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.

- Statement
- LiDAR is an airborne laser altimetry sensor that enables the generation of dense surface models with high vertical accuracy. The system provides a continuous point cloud covering the territory, which is adjusted using control areas; subsequently, each point is classified according to the type of landscape element it represents (ground, vegetation, buildings, water, etc.). This classification, as well as the extent of any manual correction performed, may vary depending on the specific dataset release. A regular grid model is generated based on the maximum elevation of LiDAR points across all classes—excluding those classified as noise or "other ground." Finally, any gaps resulting from the absence of LiDAR points are filled using the digital terrain model. The fulfilment of the parameters of quality established for this database in the technical specifications is verified: positional accuracy and logical consistency.
- Description
- Altimetric information, corresponding to the surfaces, from the LiDAR sensor.
