I am trying to reproject a Southern Hemisphere GeoTiff satellite picture from Mercator to Polar Stereographic.&nbsp; I want to obtain an image similar to the one in : <a href="http://aviationweather.gov/obs/sat/intl/">http://aviationweather.gov/obs/sat/intl/
</a> for ICAO area J or K.&nbsp; Pls. see input image info at the end of the message.<br>I tried following options to just reproject the map with not so promising outputs:<br>gdalwarp -t_srs EPSG:32761 -wo SAMPLE_GRID=YES in.tif
 out.tif&nbsp; =&gt; original image diagonally on a white background but with southern latitudes on top of northern latitudes like //<br>gdalwarp -t_srs &quot;+proj=stere&quot; in.tif out.tif =&gt; fully white image<br>gdalwarp -t_srs &quot;+proj=stere +lat_ts=

<br><br>Does someone know which are the right arguments for gdalwarp to obtain the image I want to obtain?<br><br><br>==========================================================================================<br>The input image info:
