<div class="gmail_quote"><div>Hi Blue,<br><br>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 <a href="http://www.maptiler.org/" target="_blank">http://www.maptiler.org/</a> 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.<br>
<br>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
<a href="http://www.vips.ecs.soton.ac.uk/index.php?title=VIPS" target="_blank">http://www.vips.ecs.soton.ac.uk/index.php?title=VIPS</a><br><br>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!<br>

Slightly off topic, but is there any chance the library could upgrade their web<br>
viewing system to be like OSM's slippy map or Google's? That is, a drag-able<br>
map with map tiles, leaving all of the work for the client, the libraries server<br>
would just have to host the tiles. I find the interface to the current system<br>
painful to use.<br>
<br>
A few links that might be useful are:<br>
OpenLayers <a href="http://openlayers.org/" target="_blank">http://openlayers.org/</a><br>
Google Maps Image Cutter <a href="http://www.casa.ucl.ac.uk/software/googlemapimagecutter.asp" target="_blank">http://www.casa.ucl.ac.uk/software/googlemapimagecutter.asp</a><br>
<br>
Not sure how the library does these kind of projects, but if resources are an<br>
issue, a student project at a University might help. I have a few contacts that<br>
may help.<br>
<br>
Cheers,<br>
