We already provide access to our scanned historic maps via three file formats (DjVu, jpegs, and tiffs) and now we will be re-loading all 473 of our scanned historic maps via the JP2 extension so that there will be a 4th file viewing option. From here on out, we will be loading all the scans that are in the queue via the JP2 extention. Our sysadmin is trying to determine why we are having trouble loading compound objects on the new server, but the plan is to load double-sided maps (such as historic highway maps) as compound JPEG2000 objects. When viewing our maps as JP2's, I recommend clicking on the icon that looks like two boxes hooked together. That view allows you to move your viewed area with your mouse. On the new server, the "test area" for the 6 maps that have been loaded as JPEG2000's so far is at: http://contentdm.library.unr.edu/cdm4/browse.php?CISOROOT=/hmaps2 whereas ALL of the maps currently loaded the original way are at: http://contentdm.library.unr.edu/cdm4/browse.php?CISOROOT=/hmaps We are not the first institution to load maps via the JP2 extension on CONTENTdm but I would be happy to try to answer any technical questions you might have that Linda relays to me from MAPS-L.
