SPAM-LOW: RE: [mapguide-users] MGOS2.0.1 & Raster Files Performanc

Fri Jun 6 02:54:53 EDT 2008

Hi Andy,

Yes, I'm on MGE all the time (2007 thru 2009) using ECW imagery. I don't
know how Autodesk Raster provider relates to Frank's GDAL provider (are they
related at all?), but it seems that they suffer from identical bug. If the
two are not related, then it must be something with FDO core - suspiciosly
similar exceptions get thrown if provider (any provider fot that matter)
sequentially writes to the datastore in a short timeframe - please see
ticket http://trac.osgeo.org/fdo/ticket/285, then
http://trac.osgeo.org/mapguide/ticket/323. 

I'm running my own GDAL build (with ECW support, targeting Oracle RDBMS via
ODP.NET) aside from MGOS/FDO and it works flawlessly. It has to be something
about the unmanaged FDO core. 

Regards,
Maksim Sestic

Maksim,
Are you seeing the similar issues using the Autodesk raster provider with
MGE 2009?  Or, are you trying to use the GDAL raster provider?

Hi Zac,

Could you confirm this happening on MGOS 2.0.1 too? I'm experiencing the
same problem on MGE 2009 (based on MGOS 2.0.0 with some additions, but
without any fixes though). The whole rasters thing drives me nuts for a
while :-)

Regards,
Maksim Sestic

in my experience, rasters in mapguide are currently and have have been for a
while somewhat broken.

they work initially and then fall over rather quickly

the debug info on the wiki page makes absolutely no difference
