Thank you Andrea,
Your first offer seems to be better for me. My last question about this
topic; I have read about wps standard, i may be missing some points but
just wondering that if i write wps process on geoserver side that is
receiving position as parameter and return corresponding elevation data
from dted. Is it possible to do such thing ?
