Hello,
another problem ....
I try to read data of a band of a grib File. I think , in C# dev, I must use
ReadRaster function:
My code :
for (int j = 1; j <= rows; j++)
{
for (int k = 1; k <= cols; k++)
{
byte[] buffer ={1,1};
CPLErr err = band.ReadRaster(0, 0, cols, rows, buffer, cols, rows, 1, 1);
double val = (double)band. ReadRaster(0, 0, cols, rows, buffer, cols, rows, 1,
1);
}
}
But, val stay at 0 and err is none.
Do you have an idea ? buffer is important ?
Tank you again for any help
Best regards
Pascal

Pascal,
Use the GDALMajorObject::GetMetaData() method[1].
You might want to go through the GDAL API docs[2] a bit throughly.

I have another problem.
After open grib file, I have a DataSet.
This dataset give the quantities of row, col and band.
For each band, I want to know the heading. In a band of a grib file,
there are 3 rows for heading, not counting by the dataset.
Do you know how I can do that ?
Thanks and regards,

Pascal,
First check if your file works with the gdalinfo utility. Set the
environment variable CPL_DEBUG to ON to get more detailed reports on events.
Check if you get the same error with another grib file and another
format file.

Hello,
I develop with Gdal for .Net.
And I try to read a grib File (ed 1) like this :
Dataset
ds = Gdal.Open(dataSourcePath, Access.GA_Update);
with dataSourcePath is the path of grib file (.grb).
But I have an error in debug : "... not recognised as a
supported file format."
Is this method correct to have a dataset of a grib file ?
Thank you for your help,
Best Regards,
Pascal Jaugeas
