[mapguide-users] Problem with OS Geo FDO Provider for Raster.

[Jeff_Hobbs at sjwater.com]

All,

I'm a bit confused on how to get MG Studio to read my orthos. I'm running
MGOS 1.1.0 and have applied the GDAL patch. 

A little background - 

I have three inch and nine inch imagery for much of Santa Clara County,
CA. It's quite a bit of data - rounding up about 1 tb. It is NOT sitting
on my web server.

My initial thought was to use MG Studio OSGeo.Gdal provider. I have set
the DefaultRasterFileLocation to my server with my images. I provided a
domain user name and password. I assume with this information, MGOS should
be able to access the remote server. I also selected just a few files to
ensure a fast test. The test works - but does take some time. 

I've created a layer referencing the feature source. I've add the layer to
a map. I set the extents to be the same as other layers on the map. I also
set the display scale reference to be between 1,000 and 300. 

When I load the map, it loads fine initially. When I zoom into a scale
about 1,000, the browser locks up after a few minutes I get a "status code
503 - server too busy" error and my MGOS service dies.

Any ideas on what I'm missing? Should I follow this workflow instead:
http://images.autodesk.com/adsk/files/linking_to_external_data_autodeskmap
guidewhitepaper.pdf? If so, do I have to list each image individually?
There's maybe 50,000 images. That would just be painful.

Thoughts?

Thanks!

Jeff

Maciej,

There was a binary build provided with a fix for this problem, but I see
that the source on the download site has not been updated.  I think you
can safely pull down the fdogdal source from the 3.2.1 subversion branch
to get this fix.

I'm not exactly sure where the binary patch is that was provided.  But if
you install:

    http://www.gdal.org/dl/mapguide/mg_mrsid_110.zip

then you should also get the fix.

Best regards,
