Erik, since we can publicly show it now, I can send it on the list. The site is:
http://sandbox01.dmsolutions.ca/mapmobility/ This has a couple of unique features in how we are using OpenLayers. The map tiles are taken directly from TIFF files produced for printed maps and cut up using a GDAL shell script into a TMS directory structure. At the two largest resolutions (most zoomed in), the printed maps are rotated from true north by varying amounts depending on location. So we use a pixel coordinate system for every resolution and 'reproject' real world coordinates into pixel space including a potential rotation at some resolutions. I had to do an interesting hack to baseLayer handling to make the transition from one rotation to another work nicely, which I would be interested in talking to someone about at some point :) We also 'reproject' all the point and route stuff on the fly as the rotation changes - what a pain :) Cheers Paul On 26-Sep-07, at 9:55 PM, Erik Uzureau wrote: > Awesome work, chris! > > Hopefully we'll see more people who are interested in doing work with > routing.
