<font face="Arial">Hello, i downloaded a 10GB raw image from Nasa Earth
Observatory - Blue Marble
(<a class="moz-txt-link-freetext" href="http://earthobservatory.nasa.gov/Newsroom/BlueMarble/">http://earthobservatory.nasa.gov/Newsroom/BlueMarble/</a>)<br>
<br>
It is a world image at 500m/pixel resolution in raw rgb format,
86400x42600 pixels.<br>
<br>
I want to use it with mapserver, and have created a gdal VRT file:<br>
<br>
<font face="Courier New"><VRTDataset rasterXSize="86400"
rasterYSize="42600"><br>
</font><font color="#ff0000" face="Courier New"><SRS></SRS><br>
<GeoTransform></GeoTransform><br>
</font><font face="Courier New"> <VRTRasterBand dataType="Byte"
band="1" subClass="VRTRawRasterBand"><br>
<ColorInterp>Red</ColorInterp><br>
<SourceFilename
relativetoVRT="1">world.topo.bathy.200407.3x86400x43200.bin</SourceFilename><br>
<ImageOffset>0</ImageOffset><br>
<PixelOffset>3</PixelOffset><br>
<LineOffset>259200</LineOffset><br>
</VRTRasterBand><br>
<VRTRasterBand dataType="Byte" band="2"
subClass="VRTRawRasterBand"><br>
<ColorInterp>Green</ColorInterp><br>
<SourceFilename
relativetoVRT="1">world.topo.bathy.200407.3x86400x43200.bin</SourceFilename><br>
<ImageOffset>1</ImageOffset><br>
<PixelOffset>3</PixelOffset><br>
<LineOffset>259200</LineOffset><br>
</VRTRasterBand><br>
<VRTRasterBand dataType="Byte" band="3"
subClass="VRTRawRasterBand"><br>
<ColorInterp>Blue</ColorInterp><br>
<SourceFilename
relativetoVRT="1">world.topo.bathy.200407.3x86400x43200.bin</SourceFilename><br>
<ImageOffset>2</ImageOffset><br>
<PixelOffset>3</PixelOffset><br>
<LineOffset>259200</LineOffset><br>
</VRTRasterBand><br>
</VRTDataset></font><br>
<br>
I still need to georeference the image. How can i fill the SRS and
GeoTransform labels?<br>
<br>
Also, is there some tool to convert this too big file into a tile of
smaller files?<br>
<br>
thanks for your help,<br>
