Hi Robert<br><br>Thanks for the reply, you have got me to a point where ogrinfo commandline processes an ovf file using sql authentication fine.  However it will still not display using shp2img commandline (other layer in mapfile draws fine). My layer definition is fairly simple, but I am scratching my head to think what is stopping the layer from drawing!  The points are in standard lat/long so using WGS84 (layer and map projection).<br>
