Difference: SiaInterface (18 vs. 19)

Collaborative Page for SIA Interface

The Simple Image Access (SIA) interface defines a protocol for retrieving image data from a variety of multidimensional astronomical image/cube repositories through a uniform interface. The interface is meant to be reasonably simple to implement by service providers. A query defining a multi-parameter query is used to query for candidate images. The service returns a list of candidate datasets formatted as a VOTable. For each candidate image an access reference URL may be used to retrieve the image. Direct client-directed access to a remote image/cube dataset is also provided. Images may be returned in a variety of formats including FITS, other astronomical image formats, and various graphics formats. Referenced images are often computed on the fly, e.g., as cutouts from larger images.

• Simple Image Access V1.0 (Current/legacy SIA V1.0 specification)

• Simple Image Access V2.0 (SIAV2 working draft as of fall 2009)

• VAO Whitepaper on Multidimensional (cube) Data in the VO (May 2013)

• Providing Support for n-Cubes in the VO (Rots et. al. 2013)

• Characterization V2 draft addressing visibility data (September 2012)

• Interferometry (radio) data and the required SIAV2 capabilities (A.Richards, February 2010).

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.
