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.


SIA Working Drafts

The SIA V1.0 is now at the request for comment stage on the path to becoming a recommendation.

A major update to the SIA interface, SIA V2.0, is in the planning stages. An analysis discussing the scope and concepts of SIAV2 is available in the IVOA Note below.
