world within which we live. However, relying on machine
analysis, whether with fledgling, yet fast growing, artificial
intelligence techniques or not, may not necessarily result in
better information. The provision of poorer information from
the plethora of new and capable sensing tools would be a
disservice to the society the remote sensing field was created
to serve. The basic building block of image interpretation
is image understanding and that a different type of under-
standing is required to do a forest inventory, an urban land
use map, or a wildlife habitat map. The community must re-
turn to image understanding – and that understanding will
be required to fully and effectively use the rapid advances in
remote sensing.
