Fine-scale 3D biotope mapping using ultra high resolution airborne photography and mobile laser scanning

This work was dedicated to validating an innovative scheme of combining ultra high resolution airborne photography and mobile laser scanning (MLS) for biotope mapping, which is a topic now widely highlighted for quantifying and monitoring environmental quality. The specific combination plan was to use the MLS data as the 3D references to enrich and calibrate the retrievals from the imagery, meanwhile use the ultra high resolution imagery to expand the coverage of the MLS. Further, the combination program even derived an enhanced concept, i.e., fine-scale 3D biotopes. The test case primarily verified that the proposed plan can provide a new avenue for mapping the biotopes of the spaces of interest closer to their real situations.
