[Gdal-dev] Problems with ogr2ogr?

[Moskovitz, Bob]

Hello List,
 
I am a new user of GDAL./OGR and I have a problem converting (what is supposed to be) a NAD27 California State Plane Zone 5 Mapinfo file to a NAD27 UTM Zone 11.  For some reason ogr2ogr created a file that uses WGS84. The source file was created with MapInfo 6. This is what I did:
 
ogrinfo -al -so LAND_AP_7.tab
Had to open data source read-only.
INFO: Open of `LAND_AP_7.tab'
using driver `MapInfo File' successful.
