VOPSAT (V.O. Paris Southern Atlas) is a set of southern sky digital surveys based on ESO-R, SRC-J and POSS1-E atlases.
The plates have been digitized with the MAMA microdensitometer with a resolution of 0.7 arc-sec.
Pixel resampling will allow mosaicing neighbouring Schmidt fields up to hundreds of square degrees.
A forthcoming catalog (VOPCAT) will contain detected objects with positional accuracies as good as 0.07 arc-sec.
