      abstract     = {A novel hyperspectral measurement system forunmanned aerial
                      vehicles (UAVs) in the visible to near infrared(VIS/NIR)
                      range (350–800 nm) was developed based on theOcean Optics
                      STS microspectrometer. The ultralight device relieson small
                      open source electronics and weighs a ready-to-fly216 g. The
                      airborne spectrometer is wirelessly synchronized toa second

                      investigated and specific issues such as dark
                      currentcorrection or second order effects are addressed.

                      correlation (r2 > 0.99)was found in reflection comparing
                      both measurement approaches.Furthermore, the aerial
                      measurements have a six times smallerstandard deviation than
                      the hand held measurements. Thus, thepresent spectrometer
