A Generic Framework for Library-based Mapping

of Urban Areas


How we mostly use spectral libraries

(and why it's a problem ...)

This is what happens now: we all work on our little image

spend a lot of time and effort to get suitable

endmember spectra

finally we get that library

make something with it

and then stop using the library altogether.


Obviously this is very inefficient. On the one hand we are doing the same work over and over again, even though it can often be avoided. On the other hand, there are those who don't have the skills or data access to make those libraries, but could definitely use them for their applications.

On the next page we explain our proposed approach to working with spectral libraries.
