Hi,<br>
I want to go from x,y (pixels) to lon,lat and vice versa, using
geotiffs.<br>
I have found the <a class="el"
href="http://www.gdal.org/classGDALDataset.html#af9593cc241e7d140f5f3c4798a43a668"
title="Fetch the affine transformation coefficients.">GetGeoTransform()</a>
function, but the documentations says:<br>
<br>
"NOTE: <a class="el"
href="http://www.gdal.org/classGDALDataset.html#af9593cc241e7d140f5f3c4798a43a668"
title="Fetch the affine transformation coefficients.">GetGeoTransform()</a>
isn't expressive enough to handle the variety of OGC Grid Coverages
pixel/line to projection transformation schemes. Eventually this
method will be depreciated in favour of a more general scheme."<br>
<br>
I googled a lot, but cannot find out what is meant exactly by "OGC
Grid Coverages". I am just working with a simple cartesian x,y grid.<br>
<br>
Anyone willing to explain a bit more.<br>
Thanks.<br>
