An innovative use of orthophotos – possibilities to assess plant productivity from colour infrared aerial orthophotos [PDF]

open access: yesRemote Sensing in Ecology and Conservation, 2019
AbstractStudies of ecological processes should focus on a relevant spatial scale, as crude spatial resolution will fail to detect small scale variation which is of potentially critical importance. Remote sensing methods based on multispectral satellite images are used to assess primary productivity and aerial photos to map vegetation structure.
