SPAM-LOW: [mapguide-users] Issue with Gdal DefaultRasterFileLocation with UNC path

[Martin Morrison]

My concern over this whole issue is speed.  You need your data as close and as fast as possible.  Reading raster over a network connection is not an optimal way to access the data.

Mapped drives generally don't work. Is your MapGuide server running with a login that has permissions on the network share? Running the service with the default System account will not work.

What if you use a drive letter mapping instead of a UNC?

Hi all,

I am running MapGuide 2.0.2 with the service running under a domain account.

The account has full control over a file server directory containing raster imagery in Sid format.  The imagery is in LL84.


When configuring a raster data connection with the Gdal FDO I am having issues with applying coordinate system overrides when the files reside on a file server and are being accessed via UNC path.

When I reference the file locally - i.e.  c:\myfiledirectory\myfile.sid,  I can override the coordinate system with no issues in both Studio and Maestro.  Map display is perfect.

When I use a UNC path - i.e. \\myserver\myfiledirectory\myfile.sid<file:///\\myserver\myfiledirectory\myfile.sid>, and try to use the override by refreshing to see the default spatial context I get the following error:

In studio:  A popup windows error :


The exception unknown software exception (0xc0000409) occurred in the application at location 0x00ea0a66

In the event viewer:


Out of process application '/LM/W3SVC/1/ROOT/mapguide/mapagent' terminated unexpectedly.

Maestro displays no error.

But after an attempt or two in either application, the service is unresponsive and W3SVC and mgserver services have to be restarted.


Has anyone run into this issue before?


Cheers,

Kori Maleski
