Hi,
Sorry, but I am a linux person and it usually takes me 3 times longer to
write python.
There is the python program gdal_retile.py, but if I remember, it didn't
handle my use case the way I wanted it.

Hi
I talked about this at the foss4g 2 years ago and shared a bash script where I
do exactly what you are asking for. I don't know if you consider it to be easy,
but
the example is this script:

You could add an extra print command if you want to write it in other format:
| awk -F, '{printf "%d,%d,%d,255\n", $1, $2, $3}'
To assemble a vrt and a tif I have used gdalbuildvrt command with the argument
"-separate".
You get a new vrt

sed -i -e '/VRTRasterBand dataType="Byte" band="1"/r orig_colortable_vrt.txt'

There a also a sed commands to delete certain ro
Maybe this could help a little.
I had a problem a while ago when I wanted to filter just the mask and then
assemble it again. It took some reading to get it right.
So I took the image apart with gdal_translate -b mask. Then ran gdal_sieve.py
where I got a 8 bit mask.
The tricky part was then the

Richard, thanks you for your support, I would not have done it without you!
I tried to convert one of my file
your experiment. It seems like the command that produces
"alaska_warped_sliced_at_180.vrt" is missing in your script.
I guess that step could be vital to understand what is going on.
Best regards

Hi,
gdalwarp has an option -r that allows min and max and -tr for output
resolution. But the problem remains how to assemble the results in a pyramid
the way gdaladdo does.

I would use ogr sql syntax to select whatever you would like to keep.
Experiment first with ogrinfo. Then do it with ogr2ogr. /Lars S.

Hi,
I need to convert 524 288 color png tiles to black and white pn
ttriubutes in the
57attributes.csv for aml.
The procedure is to compare the specification and the content of the csv
file.
But I remember that I played with some IW files from Germany as well and
those displayed just fine.
Good luck /Lars Schylberg

Have tried the inland water profile? This is how i did it in the past.
This is a config for ogrinfo or ogr2ogr.
--config S57_PROFILE iw
This refers how the attributes are defined differently between normal S57 ENC
and the inland water profile in
the csv files
Good luck

Hi Paul,
if You do: gdalinfo --formats | grep AERONAVFAA
does your format show up?
I could be that You have to make your own build to have AERONAVFAA included.
It doesn't show up in my debian build.
