This page provides installation and configuration tips for the MapGuide 2.1 GDAL Raster Provider. Most of the information has been compiled from individuals in the user community. This document is a work in progress and incomplete.

Installation

Jason Birch posted an ​excellent article to the news group on where to find the vendor libraries for ECW and SID.

The location of the installation files is not obvious. Jonathan McIntyre has provided the following directory layout for the various libraries:

C:\Program Files\OSGeo\MapGuide\Server\Fdo
   Gdal16.dll - Version 1.6.0.4

C:\Program Files\OSGeo\MapGuide\Server\bin
   Lti_dsdk_cdll.dll - Version 6.0.7.1407
   Lti_dsdk_dll.dll - Version 6.0.7.1407
   NCScnet.dll
   NCSEcw.dll
   NCSEcwC.dll
   NCSUtil.dll

C:\Program Files\OSGeo\MapGuide\Server\bin\gdalplugins
   Gdal_ecw_jp2ecw.dll (01/12/2009)
   Gdal_MrSID.dll (11/28/2008)

In addition, please ensure that the GDAL Provider is listed in provider.xml

Debugging

Jonathan has also supplied some debugging steps for the GDAL Provider:

1. Starting MG in debug mode
   1. Open cmd window
   2. Cd to C:\Program Files\OSGeo\MapGuide\Server\bin
   3. Type ‘set cpl_debug=on’ (no quotes needed)
   4. Type ‘mgserver run’ (no quotes needed)
   5. You should see:

      (1392) Server starting...
      (1392) Mentor Coordinate System Library
      (1392) Server started.
      

2. Setting up image in MG site
   1. Use Maestro to create Feature Source for image
      1. Create New GDAL Feature Source
      2. Add file(s) to list-you should see something like the following show up in the console:
