Hum, I read a bit http://en.wikipedia.org/wiki/K-means_clustering and not
being familiar with it, it is not obvious how that could lead to the binary
result I expect ;-) I was hoping for a ready-made solution for my problem. I'm
kind of demanding tonight ;-)
Well, too late for tonight.
I gues
Hi All,
First off, sorry this is really long with all the gdalinfo pasted into
it, but I thought is might be more useful to have real information to
look at.
I have been running down a problem caused by upgrading a server to a
newer version of gdal. Here are the details:
old server: GDAL 1

Hi Even,
The result of classification the map produce less classes than
aerial/satellites images. This is the way using k-means for you
purposes. So you need do set the border count of classes to decide is

I am testing on Windows 7 and GDAL-dev from gisinternals, both 32 and 64
