How does an individual with TIFF data (byte array) load it into a GDAL
dataset? I'm trying to eliminate writes to disk to save on time so assuming
memory is not an issue, how do I accomplish this?
Thanks in advance!

I fixed the issue by using the "MEM" driver instead of the "VRT". It was
really helpful and sped up my image output by a lot!

Oops, that is what I did. Thanks.

I have run into a bug using GDALGetMaskFlags() with GTOPO30 data with
the GDAL 1.9.0 C API. The test data includes a NoData value:

Steve,
That's good news.
I did run into the "spaces" problems on Windows (I had a space
between the comma and the table name). It caused the connection to fail.

Steve,
In my case I was getting OGR to get data from a database view, but it
could have been a table. I think OGR needs (would like?) to know which
column it can use for unque id. I would expect your view (or table)
would have a unique key column otherwise relation operations (like
joins)

Thanks Brent for your answer.
But view's primary key?
I'm missing something here...What do you mean by that? Do you mean a
column with a unique id in the view?
There is no such column in my view. Is ogr now needs a unique id in a
view? Because it was working before I migrate to linux with a

Steve,
Here's a snippet from a MapServer map file I used to access a
non-spatial MS SQL server via OGR+VRT+ODBC:

SELECT * FROM v_MyPoints

Thanks Jeff
I got now OGR_ODBC: Table ?s???s!.? has no identified FID column.
I found that several users had this problem but found no solution. I don't
have write access to this MSSQL server.
I'm connecting via ODBC to a non spatial table, but it contains latitude

Hi,
It seems that gdal2xyz.py currently supports the output of multiple
raster bands using:
gdal2xyz.py -band 1 -band 2 etc
However, when I use this in combination with the parameter -csv I do not
get the extected comma in between the values of my bands.
Extected: 5.604, 50.765, 3,
17 matches
