[postgis-users] Is there a simple way to generate polygon from random points?

[Kobben, Barend (UT-ITC)]

Really Shaozhong Shi (David)...? After all these years of open questions without any focus you cannot even lookup the functions the respondent mentioned yourself, in the excellent PostGIS  manual...?

Please have some consideration for the people putting in their time to help others. RTFM.

Compute the convex or concave hull or an alpha shape.  PostGIS provides
functions for all three of them.
