[Gdal-dev] Problems with ogr2ogr?

[Moskovitz, Bob]

Hello Frank,

There was a problem when I ran those commands on my Linux box (which is not connected to the Internet).  So, I re ran those commands on my Windows box (which is on the Internet), assuming that I would get the same results.  Looks like I was wrong.  

I am using the GDAL 1.3.1 Windows binary and I compiled GDAL 1.3.2 on my Linux box.  Below is the results of running GDAL on my Linux box.  Thank you for looking into this.

Bob,

I'm not clear on why you think the output file is in WGS84.  The
above report from ogrinfo is UTM 11 NAD27.

Best regards,
