Identify hazardous asbestos roof surfaces in urban areas and calculate the geometric parameters of the affected roofs.
Identification of buildings covered with asbestos roof, determination of roof surface, slope aspect and ridge-length by using remote sensing data. Producing, processing and analysing aerial digital images, making thematic maps.
- aerial hyperspectral imagery
- aerial laserscanning (LiDAR)
- aerial digital imagery
- on-field reference measurements
Cadastre of buildings covered with asbestos roof, LOD2 building models, geometric parameters of roof surfaces.
Potentials of the produced database
Applying remote sensing technologies and using the produced information we can identify buildings covered with asbestos roof for large areas in a short time period.
The affected population can be analysed/determined (cadastre level).
The information may be useful for companies offering novel environmental friendly materials because the costs of changing the affected roof can be determined by using the accurate roof geometry.
