Footprints and FOVs:

from October 2008 to March 2009 -- Main.FrançoisBonnarel

T.Boch developped an online graphical editor allowing to build up FOV in the format described by the IVOA note called "Footprint Overlay Specification" available here . This tool was presented in the Baltimore meeting in October 2008.

In the meantime, we had further discussions with the NVO members involved in the FootPrint service IVOA proposal (T.Budavari, Gretchen Greene). Tests examples have been provided for the description of an observation sketching out some parts of the Observation Data Model . They reuse the IVOA Characterization DM and include footprint information as the spatial support element using an STC AstroCoordArea class.The Footprint service interacts at the STC structure level which is common to both approaches. This Observation Container prototype, including dataset ID and footprint information was successfull tested for interoperability with the NVO footprint service. All this was reported at the Baltimore Interop meeting. A few revisions of the XML document examples have slightly improved the prototype in the meantime.
