[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
