I'd come across Thomas before and seen what he was doing. I agree there were a few interesting people there who had some in depth knowledge of the subject but the issue I was trying to raise within OpenStreetMap was that OSM doesn't appear to have the same mash up capabilities.
Gregory <[email protected]> comments below sum up the challenge on the OpenStreetMap side to make it easier to do this sort of thing. @@@@@ It's easier/cleaner to do 'mashups' with the Google API. With the options from OpenStreetMap you need to be brave looking at javascript, but it can be just as quick to do. There are some helpful examples of using OpenLayers(powers the 'slippy map' on osm.org) at http://wiki.openstreetmap.org/wiki/Openlayers I believe someone is working on making it easier to do lots of drawing functions over the map, like you can with Google. They are doing it as a Google Summer of Code project, but I'd wait and see what actually comes out of it at the end of the summer. Some people use the Google API(I've never looked at it myself) and you can display OSM maps instead of the Google maps (it still has the powered by Google logo, but displays an OSM copyright message instead of TeleAtlas/NavTeq). I think this is usually for people that have built a webpage/site and later decide to use OSM without rewriting their displaying code. The page for that is here http://wiki.openstreetmap.org/wiki/Google_Maps_Example Note, I'm not on the Newbies list, so my message will have to be approved or if it is helpful someone can forward it over. @@@@ To me a separate issue are the concerns about getting a better foundation on the Open Data Side. The comment about Macs was more that they tend to be used by people with an Arts background who are sensitive to presentation. To make this stuff work you need both presentation and the technical side. For example it is a lot easier to do a selection on multiple criteria if they are all in the same database. OSM has the tags so finding a playground with a drinking fountain that is within 30 meters of a coffee shop has three criteria all the information should be accessible via OSM tags. To build this sort of query from three or more separate data sources is much more complex. We can't do it easily today but using a local OSM store and something likeMaperitive it should be possible to do it with local processing so no Internet access required at the point of query. I also have some reservations about using OSM for Ottawa City stuff. They have a lot of GIS information that would work better together internally if it could be consolidated. For example Travel Planner doesn't appear to know about footpaths but most people walk to their bus stop. I'd prefer to see the city host an OSM format server which would allow it to retain control over the road network etc and ensure people couldn't decide to remove a road. For non Canadians practically all federal government GIS information is available for us to import, which is quite different than the case in Europe.
