When trying to convert a png to geotiff which is listed below:<br><br><i>gdalwarp -s_srs epsg:4326 -t_srs<br> epsg:4326 "C:\Documents and Settings\jmitchell.INSEQUENCE2\Desktop\ows2121.png"<br> "C:\Documents and Settings\jmitchell.INSEQUENCE2\Desktop\ows2121.tif"</i><br>
<br>I get the following error:<br><br><i>ERROR 1: Unable to compute a transformation between pixel/line<br>and georeferenced coordinates for C:\Documents and Settings\jmitchell.INSEQUENCE<br>2\Desktop\ows2121.png.<br>There is no affine transformation and no GCPs.</i><br>
<br>I have the coordinate bounding box that was used to create the original png.<br><br>Is their a way by using the bounding box and the png to convert it into a geotiff?<br><br>Thanks,<br><br>John<br><br><br><br clear="all">
