[mapguide-users] MGOS2 ECW Issue

[Andy Morsell]

I'm not sure if this will help with your problem or not, but thought I'd
throw it out there.

I had a problem displaying ECW (and I believe SID's too), after migrating a
test site to MGOS 2.0.  In my case, I received error messages in the
error.log file about coordinate transformation not being supported for
raster even though my images were in the same projection as my map.  I had
to open the raster data connection definitions in Autodesk MapGuide Studio
2009 beta and go into the Set coordinate system overrides section and
specify the actual coordinate system in the Override section.  Previously,
it was assigning Arbitrary X-Y, meters and MGOS was seeing that as a need to
transform to the map coordinate system, which it doesn't (yet) support.

Hi all,
I am trying to get rolling with MGOS2 and am not able to get ECW files to
display. These worked in MGOS 1.2

I have tried everything that I've found in the forum:
Replaced gdal14.dll (version 1.4.3) with gdal14.dll (version 1.4.4) Placed
libecwj2.dll in C:\Program Files\MapGuideOpenSource2.0\Server\Bin\FDO\
Placed gdal_ECW.dll from ecw_plugin_gdal14_vc8.zip into C:\Program
Files\MapGuideOpenSource2.0\Server\Bin\gdalplugins\

I have restarted the MapGuide Service with no luck and rebooted the server
with no luck as well.

I ran mgserver in interactive mode with CPL_DEBUG=ON and get information
such as:
----------------------------------------------------------------------------
--------------
ECW: NCScbmOpenFileView(D:/web/data_files/rasters/ms/lee/16_999749.ecw):
eErr =
0
ECW: FileInfo: SizeXY=6000,6000 Bands=3
       OriginXY=999000,1.752e+006  CellIncrementXY=0.5,-0.5

ECW: projection=LOCAL, datum=WGS84
GDAL: GDALOpen(D:/web/data_files/rasters/ms/lee/16_999749.ecw) succeeds as
ECW.
----------------------------------------------------------------------------
--------------

So it looks like the files are loading fine, but are not displaying.

Thanks in advance for any help!
