We have added some 160
town plans from the digital library of the University of Wroclaw.
Unfortunately, as most digital libraries do not provide direct access
to scanned material (jpg), instead embaring on a convoluted on-line
viewing options (java, zoomify, etc), we are unable to determine the
resolution of scanned images, consequently this information is not
available in the file metadata, displaying, instead, resolution of 75
dpi or 96 dpi. We have been informed that they were scanned in a range
of resolutions ranging from 300 to 600 dpi.
The easiest way to find out which plans are new, is to visit the lists,
rather than index sheets of Mapster, as all new material is labelled
accordingly (in green):
