Multi-Archive Data Integration

On-Line Archive Science Information Services (OASIS)
OASIS is a general astronomical archive access and data integration tool. It provides data from sources including IRSA, NED, CDS, STScI, LLNL, NRAO, AAVSO, HEASARC, and JPL.
RADAR
Radar is an inventory and data exploration service
Finder Chart
A visualization tool to cross-compare image data sets from various missions. The goal is to provide a finder chart showing the same region of sky at various wavelengths and epochs.
NVO Quick Sky Statistics
Generates source counts, coverage maps, and links to downloadable data for catalog holdings available through the NVO protocols, including IRSA, NED, and CDS VizieR.
Atlas - A General Data Collection Search Service
Atlas is a single CGI program which can be used to search the following data collections:

Utilities

Image Mosaics
Montage is a toolkit for assembling FITS images into custom mosaics.
Coordinate/Object Lookup
Makes use of NED and SIMBAD to look up coordinates for astronomical objects by name, as well as providing transformations of coordinates from one system to all others.
Dust Extinction Service
An interactive service that uses the maps of Schlegel, Finkbeiner and Davis to return extinction along the line of sight through the Galaxy. Returns image cutouts, and supports upload of lists of sources.
QA Tools
Quality Assurance Tools for IRSA data providers.
Cutouts Service
The IRSA Cutouts Service is a general tool which can be used to create small "cutout" FITS images (and JPEGs) from collections of data archived at IRSA. Each data set that uses the Cutouts service has a separate Cutouts user interface that allows the user to retrieve cutout images at multiple locations and sizes.
Data Tags
Returns data encoded in a published Data Tag, which link science publiactions with archives.

(Holdings)Catalogs

Gator Catalog Query
A query building service that allows users to extract data from Infrared Astronomy Catalogs held at the NASA/Infrared Science Archive.
Baby Gator
