[mapguide-internals] [mapguide-users] Adding a CoordinateSystem to MGE/MGOS

[Orest Halustchak]

Hi Maksim,

The FDO Client Utilities section of FDO Futures is there for discussion and is not an established "plan". The points included in that page are ones that some folks have raised recently. We posted the ideas so that we could start a discussion and get some more feedback. So, if you have some ideas or feedback that you'd like to throw in there, please feel free to add your comments.

Regarding CRS support in FDO, as Jason points out, FDO doesn't do coordinate transformation itself. FDO can return the CRS definition from the data source if it is known (returned as a WKT string). That definition is passed by MG to Proj4 or Mentor. MG relies on these libraries to recognize the CRS definition.

Thanks,
Orest.

Jason, is there some sort of "global" OSGeo roadmap on active projects and
code being shared among them? Like - what project depends on other projects'
deadlines, common cores (i.e. FDO in MG), etc. I guess there's a geospatial
product manager somewhere at Autodesk who actively tracks this :-) Otherwise
there will be lots of inner branching and wheel reinventing, but the purpose
stays the same.

Frankly, lack of CRS support in FDO is still mistery to me :-) MG should be
able to detect and reuse any managed feature store's CRS, where applicable
(if not explicitly overriden by MG at feature source level). This should
also solve WMS/WFS troubles on WGS84 reprojection parameters and envelope
definition.

If I understood "FDO Futures" right, there's a plan to gradually switch
general FDO architecture to client/server?

Regards,
Maksim Sestic
