Still very confused.<br><br>I have a tiff file. I want to get the metadata for that tiff but in EPSG:4326, without actually warping the image. I can use CoordinateTransformation to do this, but again it gives me different results than gdalwarp.<br>
<br>I will use gdalwarp later (realtime) to serve out an image. But if the metadata I store (from CoordinateTransformation) is different than the metadata when I warp I will run into problems.<br><br>gdalwarp gives something like minLon = 30.300001234, but CoordinateTransformation gives minLon = 30.29988787. I want to gdalwarp number but without actually warping the entire image.<br>
<br>I am not sure what .vrt file you are talking about.<br><br>Thanks again<br><br><div class="gmail_quote">On Sat, May 5, 2012 at 3:15 PM, Frank Warmerdam <span dir="ltr"><<a href="mailto:warmerdam@pobox.com" target="_blank">warmerdam@pobox.com</a>></span> wrote:<br>

Can you think of a way that I can get the same metadata as gdalwarp would give<br>
for a warped image without actually warping the image?<br>

Just open the .vrt and read the corners (that is compute them from the<br>
size and geotransform). There will not be any actual warping done just<br>
to get this metadata from the .vrt but you will get the result<br>
representative of the reprojected image.<div class="HOEnZb"><div class="h5"><br>
