[postgis-users] multipoints to raster

[Radan Šuba]

Hi all,

I want to create raster from multipoints geometry where value of pixels is
Z value of points. I want to do everything in the database. Is there any
simple query for that?
So far, I have found the quite complicated way: First create a empty raster
with ST_MakeEmptyRaster, secondly ST_AddBand and at the end ST_SetValues
which is new functions release recently (PostGIS version 2.1). I am
wondering how have these conversion been done until now?

Thank for any answer
Radan
