Exactly. OGR will not try to guess the
Hello all,
I'm new one to gdal. Now I have to do some spatial data format
transformations, and I know of gdal from the internet. To avoid compiling
gdal source data I download FWTools2.7.4. According to some guidances from
the internet , I copy gdal_csharp.dll, gdalconst_csharp.dll, ogr_csharp.
For context, please see this posting from April:

thanks

Thanks for the response.
Are the code snippets below what you mean by the memory drivers?

target_dr = gdal.GetDriverByName ('MEM')
target_ds = target_dr.Create ('',

Julianne,
You can use the Memory raster driver just like you would use any other
format driver. Use the ReadRaster() function.
Refer to http://www.gdal.org/gdal_tutorial.html

I believe that I have the example working. When using the command 'print
an_array', it wasn't showing the parts that contained non-zero data. Once I
realized that, everything seems to work as expected.
Thanks for the support.

Hi,
i am a little confused. I am using the gdal/python and trying to read
values from a grib file (i can email the file if needed). I am using
pygrib to compare against. I do this with the following code:
import struct
import pygrib
from osgeo import gdal
from osgeo import ogr
from osgeo import
Matt,
At a quick glance I would say pygrib is outputting in kelvin and gdal
Celsius. also it looks like there not in the same order.

I have noticed the same thing. My question is why would gdal do a conversion
that you had not asked for? We create some of our own grib2 files that may at
times have unitless values. For some odd reason they are being converted to
Celsius as well.

gdal uses degrib to read grib files, best I can tell is it does whatever
degrib does by default

Hello,
While I am compiling the code (cpp version) given in
http://www.gdal.org/ogr/ogr_apitut.html
I am getting lot of compilation errors. I am not sure why they are coming as
it is the code directly taken from the above given link. Can you please look
at the screenshots attached and let me know
Pradeep,
I see your ogr_core.h file is in a separate directory. Are you compiling ogr
without the gdal files?
Also, I couldn't open the screenshots archive.

Hello Chaitanya,
ogr_core.h is present in the same directory where .cpp is present. Gdal
files, you mean the header files which are required right, I have included
all of them and are present in the same directory.
Thanks and Regards,

Pradeep,
I have seen your screenshots.
No wonder you got the multiple declaration errors, with all the
'unterminated #ifndef' and '#endif without #if" errors. You should try to
identify the source of those errors.
I never compiled GDAL/OGR files separately from the source tree. Check if
you get
