Slide16The demo sites
for the AlpMon services are the Austrian Bundesland Steiermark /
Styria and selected bark beetle sites in Lower
and Upper AustriaThe AlpMon Services
can easily be expanded to
full Alpine scaleTest users are from a

Slide17Data analyses based on time
series analyses makes cloud processing absolutely
necessary.EODC – Infrastructure must be available sustainably, as forest
monitoring services should be offered continuously
.The timely resolution of cloud-free
Sentinel 2 – data is limited particularly in Alpine regions because of
frequent cloud cover, 4 satellites instead of
2 satellites would be nice.
Bottle neck of operational services is
very often the limited
information content of satellite data.
Users
who
apply
other methods of information retrieval often have detailed requirements
regarding information depth
and accuracy that cannot always be met by EO-based methods
.
