Just Shaun and Stephen in the pub last night, but we had a good chat about various OSM ideas. I'm trying to remember them all. Ideas seem to come thick and fast after a few pints, and then I forget to follow them up.
Stephen was showing us his trackmyjourney.co.uk stuff. Today I notice that this is not mentioned on the wiki at all, and barely mentioned on the site anywhere. Stephen's hiding his light under a bushel. It's a nifty little J2ME app which he has been busily adding features to. It does GPS stats, hence the name, but also shows OSM maps, lists nearby POIs, and allows you to record waypoints with annotations suitable for later inputting into OSM.
...but what would it take to have a mobile editor submitting changes directly? Authentication seems to be the main hurdle. A simple interim solution might be for OSM to provide a basic web interface for editing/creating a node (and setting tags on it). The app could then launch a mobile web browser pointing at the URL (login and cookie session done as normal) The app already launches a browser to view read-only node data.
He was also explaining about how he had to code graphics routines to break up areas into triangles, and position lettering for road names. There's quite a few mobile apps like this which have a lot of logic which might be described as "rendering" logic. How difficult would it be to rip this out, and have it available as a standalone desktop rendering system? It'd be fun to see lots more alternatives listed on the rendering page. Apps for creating one-off map images or tile sets. Java based renderer could done as a JOSM plugin.
landuse=farm isn't currently shown on mapnik at all, which led us onto the idea: Editors should support some kind of landuse "layer". We could then aim to "complete" this data, such that there is nowhere without a landuse. In england that would probably mean a whole lot of landuse=farm, but equally in cities we would aim to create a background layer of residential/commercial/industrial areas.
So Next time (in a fortnight) we'll be in a more central location, which might mean more people. I'm sure there will be more crazy beer-fuelled map chit chat. Get yourself signed up!
