The hydrographic basins of Andalusia will have LiDAR (Light Detection and Ranging) flights, a technology that allows the collection of maximum precision data for monitoring and evaluation in order to anticipate the risks of flooding and reduce the damage caused by this natural phenomenon. The Ministry of Agriculture, Livestock, Fisheries and Sustainable Development has put out to tender this service for a value close to one and a half million euros.

The LiDAR technology constitutes a solution for the assessment of the risk of flooding, since it allows to achieve an exhaustive knowledge of the elevations of the terrain and the objects located on it. The Andalusian Government points out that its use will facilitate the obtaining of numerous highly accurate information for territorial analysis such as the study of flood areas, digital terrain models or the automatic detection of surface modifications, among other applications.

This tool contributes to the fight against climate change, taking into account that the risk of floods is one of the main threats of global warming. For this reason, the Ministry considers the development of systems and the obtaining and appropriate treatment of information “essential” to reduce flood risks in Andalusia.

The project will serve to update the flood hazard and risk maps of the intra-community basins and to improve the information on the areas of potential significant flood risk.
