3edata offers data collection and processing services on vegetation cover and biomass accumulated in fire defence infrastructures: Biomass management strips. The objective is to provide the necessary information for the preparation of reports for the declaration of the abandonment of plots or support for the monitoring of the network of biomass management strips and compliance with safety distances.
Sectoral regulations on forest fires, the maintenance of communication or energy transport infrastructures, define the areas in which vegetation must be maintained in a state that reduces the continuity of fuel and thus slows down the advance of fire in the event of a fire. This affects communication networks and energy or gas transmission lines, electrical substations, telecommunication stations, the entire urban perimeter and infrastructures for public use.
From a methodological point of view, the service is based on the use of Drones equipped with LiDAR and multispectral sensors, or very high resolution images captured by satellite. Passive sensors such as multispectral cameras provide information on the type of vegetation cover, while the LiDAR sensor helps to define the structure of the vegetation cover. The combination of the two allows the calculation of vegetation height within the Management Faces and the identification of fast-growing species susceptible to removal.
The resulting product indicates, for each cadastral parcel within the biomass management strips, the classification and determination of the occupied area of each vegetation class, the calculation of heights, the estimation of fuel load and the calculation of safety distances to infrastructure (rural centres, communication routes or energy distribution lines).
The results report can be elaborated in order to inform the person in charge of the Biomass Management Strip about the actions to be carried out or to certify the correct execution of the maintenance works of the Biomass Management Strip.
