Filtering
Cutout
Resampling on a provided WCS
Etc .....

AccesData as one of the DataLinks for a given Dataset
• Start from a dataset known by its PUBDID (whatever it is coming from ....)
• Discover AccesData as
• Retrieving a description of the AccessData parameters
• Client build a menu for this parameters
• Simulation with Aladin screens ----> next slides

Querying for a resample by forcing output WCS

Result: stored and virtual images(Better sampling and flipped RA)

questions:
• AccessData Method (SIA, SSA)possible without preminary QueryPhase ? There are Use cases for that.
• Is that two different services (Query and AccessData) ?
• At which level do the AccesData service parameters will be described?
– Service ?
– Collection ?
– Dataset ?
