Alexander,<br><br>You can use the GDALGetGeoTransform() or GDALDataset::GetGeoTransform() to get the affine transformation coefficients which can be used to calculate lat/long to col/row and vice versa. You can see the utility script gdal_merge.py for an example.<br>

Hi,<br>
<br>
I have a georeferenced raster and coordinates of some point (lat, lon)<br>
inside raster. Is it possible<br>
to convert this lat/lon coordinates to raster coordinates (column and row)?<br>
<br>
I use GDAL 1.6.3 with Python 2.5 (installed with OSGeo4W installer).<br>
