The yourSkyG custom astronomical image mosaicking software has a web
portal interface that allows custom access via
ordinary desktop computers with low bandwidth network connections to
high performance mosaicking software deployed
on a computational grid, such as
NASA's Information Power Grid (IPG). In this context, custom access refers to
on-the-fly mosaicking to meet user-specified criteria for region of
the sky to be mosaicked, data sets to be used, resolution, coordinate
system, projection, data type and image format. The portal uses pipelines
and data caches to construct multiple mosaics on the grid with high throughput.
