This is IRSA's Hierarchical Progressive Survey (HiPS) node. HiPS is a hierarchical scheme for the description, stoage, and access of sky survey data. The system is based on hierarchical tiling of sky regions at finer and finer spatial resolution which facilitates a progressive view of a survey, and supports multi-resolution zooming and panning.
This is IRSA's implementation of version 2 of the IVOA Simple Image Access (SIA) protocol. Our SIA v2 service allows a rich variety of searches against IRSA's varied holdings.

An IVOA Identifier is a globally unique name for a resource within the Virtual
Observatory. This name can be used to retrieve a unique description of the
resource from an IVOA-compliant registry or to identify an entity like a
dataset or a protocol without dereferencing the identifier. This document
describes the syntax for IVOA Identifiers as well as how they are created. The
syntax has been defined to encourage global-uniqueness naturally and to
maximize the freedom of resource providers to control the character content of
an identifier.
Registries provide a mechanism with which VO applications can discover and
select resources - first and foremost data and services - that are relevant for
a particular scientific problem. This specification defines an interface for
searching this resource metadata based on the IVOA's TAP protocol. It specifies
a set of tables that comprise a useful subset of the information contained in
the registry records, as well as the table's data content in terms of the XML
VOResource data model. The general design of the system is geared towards
allowing easy authoring of queries.
