All, Using GDAL trunk, I can read and reproject a personal geodatabase using the internal projection as the source projection. However, when I use sql (as I need to add a new field to the output), the source projection can no longer be read.
C:\temp>ogr2ogr -t_srs EPSG:4326 -f "ESRI Shapefile" temp1.shp CL_01_LDS_20101201_A.mdb CL_01_LDS_20101201_A_Contour_Smoothed Warning 6: Normalized/laundered field name: 'Shape_Length' to 'Shape_Leng' C:\temp>ogr2ogr -t_srs EPSG:4326 -f "ESRI Shapefile" temp1.shp CL_01_LDS_20101201_A.mdb -sql "select * from CL_01_LDS_20101201_A_Contour_Smoothed" Can't transform coordinates, source layer has no coordinate system. Use -s_srs to set one. Mike -- Michael Smith Remote Sensing/GIS Center US Army Corps of Engineers
