HiPS : Hierarchical Progressive Surveys
HiPS is the hierarchical tiling mechanism which allows one to access, visualize and browse seamlessly image, catalogue and cube data.
This page provides links to HiPS documentations and tools notably to generate progressive surveys from your own datasets.
The Aladin Lite application above gives you an overview of what HiPS are. Zoom in on a particular region and better resolution tiles for the DSS2 background survey will be loaded. Red square represent SIMBAD objects. Zooming in will reveal more and more sources.
The HiPS method is developped by CDS since 2009.
In October 2015, the International Virtual Observatory Alliance decided to standardize HiPS. The HIPS Recommendation 1.0 is available on the IVOA site.
A HiPS reference paper is also available since 2015 in A&A → 2015A&A...578A.114F.

The hips2fits service allows one to generate FITS images cutouts of arbitrary size and resolution from a given HiPS.
