---++ Collaborative Page for SIA Interface

The Simple Image Access (SIA) interface defines a protocol for retrieving image data from a variety of astronomical image repositories through a uniform interface. The interface is meant to be reasonably simple to implement by service providers. A query typically defining a rectangular region on the sky is used to query for candidate images. The service returns a list of candidate images formatted as a VOTable. For each candidate image an access reference URL may be used to retrieve the image. Images may be returned in a variety of formats including FITS and various graphics formats. Referenced images are often computed on the fly, e.g., as cutouts from larger images.

Since late 2009 [[http://www.ivoa.net/Documents/SIA/20091116/][SIA V1.0]] is now an IVOA Recommendation.

A major update to the SIA interface, SIA V2.0, is in the planning stages. A partial working draft is available at the link above, as well as related analysis papers as noted on this page.
