[gdal-dev] gdal_translate upside down image

[Greg Ederer]

Hi,

I'm running gdal_translate against a VRT file:
<VRTDataset rasterXSize="751" rasterYSize="801">
  <GeoTransform>-20.05, 0.1, 0.0, 40.05, 0.0, -0.1</GeoTransform>
  <SRS>
                GEOGCS[&quot;WGS 84&quot;,
                        DATUM[&quot;WGS_1984&quot;,
                                        SPHEROID[&quot;WGS 
84&quot;,6378137,298.2572235630016,
                                                        
AUTHORITY[&quot;EPSG&quot;,&quot;7030&quot;]],
                                        
AUTHORITY[&quot;EPSG&quot;,&quot;6326&quot;]],
                        PRIMEM[&quot;Greenwich&quot;,0],
                        UNIT[&quot;degree&quot;,0.0174532925199433],
                        AUTHORITY[&quot;EPSG&quot;,&quot;4326&quot;]]
  </SRS>
  <VRTRasterBand dataType="Float32" band="1"  
subClass="VRTRawRasterBand">
    <SourceFilename relativetoVRT="1">10day_precip.bin.1999121</ 
SourceFilename>
    <ImageOffset>0</ImageOffset>
    <PixelOffset>4</PixelOffset>
    <LineOffset>3004</LineOffset>
    <ByteOrder>MSB</ByteOrder>
    <NoDataValue>-999.0</NoDataValue>
  </VRTRasterBand>
</VRTDataset>

I just noticed that the resulting GeoTIFF is upside down.  Is this a  
problem with my GeoTransform values?  If so, what values would produce  
the image right side up?

Thanks!

Greg
