<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">I have an image with UTM coordinates across the international date line (longitude 180E or 180W) - please refer to the header information below, and now I want to convert this to a global projection Geographic WGS84 with GDALWARP. It seems the calculation for the output image size is wrong. Please confirm.
