An All-Sky Data Service Astronomical Data Analysis Software and Systems III ASP Conference Series, Vol. In recent years digital information from such surveys has become much more widely distributed within the astronomical community, but it remains difficult to use.
Data come in different formats, projections, coordinate systems, equinoxes and scales.
This makes it tedious for users to get at the data. SkyView addresses these essentially geometric issues - providing the data to users in a convenient form, and allowing astronomers to concentrate on research rather than geometry. is also a single source for many of the most useful astronomical surveys. In the past decade digital versions of several all-sky surveys have become available. The explosion in the information processing capability of computer systems has meant that the actual images from these surveys can be delivered to the community rather than simply catalogs of interesting objects derived from the images. Some of these surveys have been distributed to the astronomical community on CD-ROM's.
