There is a section called Examples of Spatial SQL in
http://trac.osgeo.org/postgis/wiki/UsersWikiMain
I think this is the best place.
Otherwise if you can come up with a robust, generic ST_RemoveSpeckle(rast, more
parameter) plpgsql function I can add it to the trunk in the script/plpgsql
folder. Those are plpgsql prototypes to be implemented in C if we find time of
fund.

Hi Tom,
I personally publish these kind of scripts to the PostGIS wiki.

ok. I will try a bit of plpgsql'ing.
That reminds me to another question:
is there any place that people can drop their own scripts for a wider
audience?
I know there is some postgis wiki but it doesn't seem very active or
structured.
I would love to share my scripts and see some scripts from others.
chrs,
Tom

In my idea staying with the algebra functions should be doable, even
with complex speckles.
As long as the mask is big enough (finding speckles of max N pixels
takes a 2N x 2N matrix) one should be able to run a neighbourhood scan
outwards from the centre pixel. With some smart iterations that might
work, I just need to start learning plpsql or something...
Would you agree that that kind of method would be faster than
vectorizing?
I can't answer this as I haven't played much with ST_MapAlgebraFctNgb.. It
all depends on the size of the window.
Give it a try! plpgsql is very easy and you can start from the example in
the doc.
