questions about setting up SOS

[Yewondwossen Assefa]

Sorry I missed this e-mail.

yes the 2 layers should be defined. Plus I think you need to define the
sos_[item name]_componenturl where item_name is the attribute name in 
your data that contains the values of what is measured. So your 2 layers 
should have each a sos_[item name]_componenturl pointing to the 
temperature and salinity fields. Those values will be returned when 
doing a GetObervation request.

Later,
