<font face="Arial">Hello all,<br>
<br>
i'm trying to create an VRT file for a raster in azimutal equidistant
projection. I am almost sure the projection i should use is<br>
<br>
+proj=aeqd +lat_0=YYYYY +lon_0=XXXXX +x_0=0 +y_0=0 +units=m <br>
<br>
XXXXX and YYYYY being the raster's center coordinates.<br>
<br>
I know the pixel width is 1000 meters, but i don't know how to write a
geotransformation since i don't know the upper left pixel coordinates.<br>
<br>
Anyone can help me? Can i define a geotransform with a central pixel
instead of the upper left one?<br>
<br>
<br>
<VRTDataset rasterXSize="480" rasterYSize="480"><br>
<SRS>+proj=aeqd +lat_0=39.177500 +lon_0=0.249722 +x_0=0
+y_0=0 +a=6371000 +b=6371000 +units=m</SRS><br>
<GeoTransform>??????, 1000, 0, ??????, 0,
-1000</GeoTransform><br>
<VRTRasterBand dataType="Byte" band="1"
subClass="VRTRawRasterBand"><br>
<SourceFilename
relativeToVRT="1">cullera.raw</SourceFilename><br>
</VRTRasterBand><br>
</VRTDataset><br>
<br>
Thanks,<br>
<br>
