Scientific paper

We present high-level user and web services for dealing with astronomical survey geometry of arbitrary size and complexity. Based on our high-performance spherical library, we built an on-line public repository of footprints pre-loaded with the coverage of some of the most widely used datasets today including the Sloan Digital Sky Survey, the Galaxy Evolution Explorer and the Hubble Space Telescope exposures. We publish a web-based toolkit that enables advanced spatial searches for regions of interest on the sky, Boolean operations on selected footprints (union, intersection), on-the-fly visualization, and exact area computation. We also provide an easy-to-use interactive footprint editor, as well as a simple upload facility. The results of the searches and region manipulations can be saved and published on the footprint server or downloaded in various formats, including ASCII and the VO-compliant Space-Time Coordinate (STC) region representation.
