Frank, does GDAL support an external .prj file for rasters? I found an email from 2003 where you mentioned that you were "in no immediate danger of implementing such a .prj file fallback feature for all the coordinate-system-less drivers" :)
You're right that MapGuide 2.0+ requires that the coordinate system of the data source matches the coordinate system of the map it is being displayed in. As for creating a coordinate system override, yes this is quite possible. In MapGuide Maestro and in Autodesk MapGuide Studio you do this at the data connection level. In MapGuide Maestro, there is a section called "Coordinate system override". Click on the "Refresh" button to load in the data set's implicit coordinate system. Double-click on the "Default" entry to bring up the override dialogue, and then click on the ellipsis (...) next to "Target" to set the actual coordinate system. In Autodesk MapGuide Studio (2008 at least), there is a section called "Set coordinate system overrides". To use it, click on the "Refresh" button to load the dataset's implicit coordinate system, highlight the default spatial context, and then click on "Edit" to bring up a coordinate system picker. Jason -----Original Message----- From: Frank Warmerdam Subject: Re: [mapguide-users] How do i load raster in MGOS 2? OK ... I will note that this this gdalinfo report looks ok, but the dataset lacks a coordinate system definition as might be expected from a raw tiff file with a world file (.tfw). I must admit I'm not too familiar with this aspect, but I suspect MapGuide has recently been changed to require a coordinate system definition. There is a mechanism to provide the coordinate system as an override, but I'm not exactly clear on the process. Perhaps someone else can make a suggestion. There are also mechanisms using FWTools to assign a coordinate system to a TIFF (turning it into a GeoTIFF) if you would like to pursue that angle. _______________________________________________ mapguide-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapguide-users
