[mapguide-internals] MapGuide OSM Sample Project

>From my "developer" perspective,

Assuming we can get the data properly classified and "fdo'ed", it would be useful for localization testing and for performance testing.  Ideally, we should fdo2fdo the entire data set to all of our supported providers.  Since the dataset is large, it may also be useful for benchmarking comparisons between the providers.

And the entire data set is "open".  We can pass it around freely and maybe even stick it up on OSGeo downloads.

There may also be some benefits for Autodesk.  This data set may be larger than the vector datasets currently being used in-house for testing and development purposes.  And I believe it is also multi-lingual.  Bigger than (something)... free... and multilingual...

A good dataset will be instrumental for effective community participation in both development and testing.

Regards, 
Trevor

Hi Zack,

Why should we be putting effort into demonstrating something (static map of the world) which Google Maps already does better than we can ever hope to do with OSM data?

don't we have SLD which we could consume?

if FDO was transparent, FDO would not be an issue

we should be domonstrating the best free global dataset
with MG doing the rendering, anything less is a cop out

for now simple php scripts can overcome the FDO polution

so i reckon the first step, is to take a standards based SLD
and import it into a mapguide map

we can have a php script to overcome specific FDO class name
issues between FDO providers

then we have a really good dataset/map to reference

OSM data is already available FDO readable, lets work with that,
tho SQLlite i think is the best :)

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.
