Towards Better Transferability
In the previous sections, we identified the lack of transferability as a potential major
impediment for the use of remote sensing methods, discussed possible causes, and
illustrated the problem with some examples from our own work. In the following,
we want to explore some possible solutions, and make recommendations to overcome the problem and stimulate the uptake of remote sensing in Natura 2000 habitat
conservation.
