Hi!
I'm new to Postgis and would really like to get some help on getting a
concave hull from an array of points.
For example:
I have an array of points - longitude and latitude of buildings in
particular area in the city. I already managed to get a convex hull
polygon from this array of points, but this is not really helpful. What
I'm trying to get is some kind of concave hull polygon from an array of
points, which I would further like to use in Google Earth kml file.
Thanks.
Hi Aleš,
Does ST_Union() help you at all?
ATB,
Mark.
