[mapguide-internals] MapGuide OSM Sample Project

[Traian Stanev]

I agree that OSM is perhaps not very relevant for the average MapGuide user (which is partly why I gave up :)). Maybe if someone wanted to use MapGuide's RenderingService as a pre-rendering backend for large scale map tiles, or to visualize OSM itself... But there are already dedicated renderers for OSM which produce similar quality to MapGuide, and there must be a way to directly consume their output as a backdrop in a MapGuide map -- that approach would be less effort.

P.S. By the way, a cool use for OSM is an offline maps application for Android, as shown here http://www.mapdroyd.com/

Someone could pipe it through FME (which supports all these formats) a
bit more easily :) Would have to somehow automate the process though,
so I guess licensing may be a concern. There are also some commandline
tools (like osm2pgsql) that could help get the data into a format we
can use with FDO. Sure would be nice to be able to start from SQLite
though.

Not sure of the value as a sample dataset. Much of MapGuide's value
proposition is in its server-side capabilities, and without structured
data (assessment, zoning, etc) this may be hard to showcase. OSM is a
greatbackdrop though. Would be great if we could take a region with
extensive open geodata (DC? Vancouver?) and bundle/maintain a
high-intelligence local sample using both OSM and local gov't data.
