I am looking for an anti-aliasing function to smooth out the pixellated effect
between raster values. I have tried the various interpolation methods with
gdalwarp and have also increased the resolution of the raster to try and
minimise the effect, to no avail.
Is this a function to be added soo

Hi,
Am trying to use gdaldem but it says this is only available with GDAL 1.7.0,
"Tools to analyze and visualize DEMs. (since GDAL 1.7.0)"
I cannot find the download link?
many thanks in advance,
Chris

I am having trouble converting a single band raster (.asc) when using the GDAL
utility gdal_translate (version 1.6)
This is the command...
gdal_translate -of GTiff -co "TILES=YES" -expand rgb FILEA.asc FILEB.tif
I get this message
Error : band 1 has no color table
I want to be able to
