Hi, I need to write a query sql where is need to split a line over many points.
I know the postgis 2.0.0 has the ST_Split(line,point), but it work on 1 only point, not on MultiPoint. So I can't use it directly. The only think i can suppose to do is develope a ricorsive procedure - write a procedure that using the ST_Split() can split a line over a point output two lines and use this two lines to call again himself on the remains points. - But I have many perplexity because I don't know if is possible to write a ricorsive method using the pgplsql, and this ricorsive method will be used in a query sql. And perhaps there is a more easy method. Any hint and suggestion is welcome, thx, -- ----------------- Andrea Peri . . . . . . . . . qwerty àèìòù -----------------
