Nikos,

The .HDR file contains the same information as in the ESRI .HDR format, but with
a different format, so it is not automatically recognized.

>From the info in the .HDR you can build a VRT file (
http://gdal.org/gdal_vrttut.html ) referencing the .BIN. For example for
AFRICA.BIN :

<VRTDataset rasterXSize="984" rasterYSize="900">
  <SRS>WGS84</SRS>
 
<GeoTransform>-26.041666666,0.08333333,0,40.041666666,0,-0.08333333</GeoTransform>
  <VRTRasterBand dataType="Int16" band="1" subClass="VRTRawRasterBand">
    <SourceFilename relativeToVRT="1">AFRICA.BIN</SourceFilename>
  </VRTRasterBand>
</VRTDataset>

Otherwise you can find free DEMs as GeoTIFF at http://srtm.csi.cgiar.org/ (at a
much higher resolution)
