There are some areas that I’m struggling with though and I’m hoping someone can help. Basically I was struggling to get layer up and running that use tif’s with associated tfw geo-referencing files in Mapguide, so I switched to the trial version of Mapguide Enterprise and was able to import a large number of tifs and tfws all from one folder on the server. I then used Maestro to render out tiles for the various zoom levels and the results were quite good if a little time consuming and labour intensive for the server.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The trouble is that the liscence has now expired on the Enterpise trial and we have had to revert back to Mapguide O/S as we don’t currently have the budget for a full licence. This means I’m back to trying to achieve a similar solution with GDAL FDO which I’m sure is achievable. So far I’ve managed to import a bunch of tif’s into a GDAL FDO Data source using the rasterconfig.php file that I got from the osgeo website. I’ve then gone on to substitute the Autodesk Raster Data Source with the GDAL FDO. Maestro does list the tif files that are now in the GDAL data source but this takes an age, and any tiles rendered out are just blank.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Can someone please point me in the right direction?
