[gdal-dev] Get dataset area after geotrasform between coordinate systems

[Finegan Thomas-QTF001]

Hello,
You can specify geographic extents of the output using gdalwarp's -te (target extents) parameter.

Subject: [gdal-dev] Get dataset area after geotrasform between coordinate systems

Hi,

I'm using gdalwarp to convert a raster dataset from EPSG:4326 to EPSG:2202

$>gdalwarp -s_srs "EPSG:4326" -t_srs "EPSG:2202" inputfile.tif outputfile.tif

after that, the output file is correted converted to the new coordinate system, but the output raster image has some blank area at the boorders. I need obtain the lower left corner coordinates from the output raster file including the blank area.
My question: is enought use the information obtained from gdalinfo (lower left corner coordinates)?
It does includes the blank area?

Is there a way to cut-off these blank area from output file or just inform gdalwarp to crop the image just to valid data?
