At the end of last year I tried to encourage the use of OpenStreetMap within Launchpad rather than the existing Google Maps; there was a bug and a blueprint for people to comment on and I hoped that we might see Free Software embrace Free Data.
Since those bugs were first filed OpenStreetMap has come on leaps and bounds; it's saved lives across the world and has led at the forefront of a data revolution that everyone is getting into. The quality of the map data is improving rapidly, you can compare the coverage in your local area to Google's to see for yourself. Importantly, the barrier for entry to OpenStreetMap is incredibly low; if your street isn't on the map it's easily added.
Sadly it seems like the logical marriage of Free Software and Free Data might not be; the blueprint has been marked obsolete and the bug closed with the note "We might reconsider this in the future when OSM provides all features that Google Maps does". I'm not sure what these features are, maps over https perhaps, but it is wrong to think that we need OSM to provide this. OpenStreetMap is a database of geograhic information that anyone can download and use as they like, even with the Google Maps API; we can provide required features.
Launchpad is Free Software, but Google does not provide Free map data;
Google provides map data at no cost. Would we host Launchpad servers on
Windows Server if it was provided without cost?
A quality of Open Software that makes it better than closed equivalents is that it's Open. We all know this and need to apply the same thinking to data.
