Hello, (Sorry for my bad english I haven't wrote in english since a while) I'm using OGR and GDAL !
I have to work with Satellite picture and ESRI shape file.
My goal is to get pixel value (x,y) in my satellite picture from the data
contains in the shape file!
My data are in decimales degrees and in order to convert them in pixels
reference, I used the GDAL fonction below
GDALGetGeoTransform( hDataset,GeoTransform);
and using Geotransform data's in order to convert geodata to pixels .
But the probleme is that the geographic data needed to make the convertion
have to be in meter, I think...
Xp = padfTransform[0] + P*padfTransform[1] + L*padfTransform[2];
Yp = padfTransform[3] + P*padfTransform[4] + L*padfTransform[5];
I suppose there are a fonction like ogr_transform that could convert decimal
degrée to meter in WGS84 UTM 31 for exemple.
If someone got clue to solve my probleme he gonna help me a lot!
Thanks for advance
Nicolas
