SKICAT Problems addressed by SKICAT:

• Too voluminous for human processing:
• 3,000 plates, each having 23,040 x 23,040 pixels, 10¹² bytes of data

• Most objects too faint for recognition by inspection, need automated methods.
• Need an objective/consistent classification scheme to be applied on about a half billion sky objects to be detected.
• Cataloguing is tedious, expensive step needed before further scientific analysis can be performed.
