I am not sure how popular are .shp files. The map I used in my examples are SVG path description. SHaPe files a very popular with mining & oil companies => potential clients with big wallets.  ESRI are the defacto standard for GIS.  There are also probably a lot of smaller organisations limping by with data locked in old ESRI versions because upgrading is too expensive.  Might be a good collaboration with your local GIS group. cheers -ben Our next goal is to represent GPS coordinate and cities. We will then probably try to show some visually interesting data (e.g., flights, tweets). Having this run at the top of Roassal @ Amber will come for free. Stay tuned! Also, in december, when I will visit inria @ Lille, I would like to push Athens more into Roassal. There are free shapefile maps in sites like this http://www.statsilk.com/maps/download-free-shapefile-maps Impressive website.

We have found description in SVG and found a couple of formulas to map longitude and latitude into pixels. So we will have something vectorial very soon. If someone has some ideas, data, examples the we will be very happy to take them as challenges!
