[OpenLayers-Dev] pgRouting + OpenLayers

[Paul Spencer]

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
