Hi Blue, I've been experimenting with just that question over the last while, prompted by when I first saw Google Maps Image Cutter. Image Cutter can't actually cope with big images (when stuck together the index plans make an image over 300megabytes in size -- Image Cutter just kind of coughs and goes silent) but gdal2tiles/maptiler http://www.maptiler.org/ can cope with images up to multiple gigabytes, and can use georeferenced images. I found Openstreetmap because I needed an unencumbered source of data to georeference maps for conversion with gdal2tiles/maptiler.
The difficulty comes with the most detailed layer of images. They're not neatly arranged and so would need to be individually georeferenced by hand and then converted. As I said there's over 2300 digitised at this stage so you're talking a project which would take years. Even combining the 26 or so index plans into a single image was tricky until I found vips/nip2 http://www.vips.ecs.soton.ac.uk/index.php?title=VIPS So the kind of good news is that on my own desktop here I have a fully functional openlayers "slippy map" of all the digitised index plans. I've also gotten the main plan and some of the index plans viewable as overlays in Google Earth. Hopefully I should be able at some stage to get something added to the website -- however I'm just a graduate librarian, and I'm about to leave the maps section so it might take me a while to convince people. I am working on it though! Cheers Keith > Slightly off topic, but is there any chance the library could upgrade their > web > viewing system to be like OSM's slippy map or Google's?
