Kenneth, That's what I don't understand. The features are in an ESRI personal geodatabase when I use OGR and the tables as they are seen don't have other geometry types e.g. in ESRI you can't have mixed geometries in a featureclass/table. I thought that the OGR was having trouble reading the geometry type which is why I converted the personal geodatabase to PostGIS. The conversion went without problem; however, it still sees each table as having all geometries which I know is not the case.
I just downloaded Maestro and was able to set the proper geometry to display, but there isn't a preview in Maestro? So I saved the layer and opened Autodesk MapGuide Studio 2008 and noticed that the layer showed an error on the "Feature Class" dropdown. It appears that Maestro sees the feature class differently than MapGuide Studio (MapGuide Studio<Feature class=FdoPostGIS:public~taxparcel> and Maestro<Schema=FdoPostGIS:public-x7e-taxparcel>. Not sure why or what this means, but I can't jump between the two environments. In which environment does the "Preview" button that you mentioned reside? Thanks again.
