    3636  Converting one or a set of source geometries to one raster can be performed like this in PostGIS:
    3737 
    38 {{{#!sql raster ST_Union(raster ST_AsRaster(source_geom, list of parameters for raster specifications))}}}
     38{{{
     39#!sql
     40raster ST_Union(raster ST_AsRaster(source_geom, list of parameters for raster specifications))
     41}}}
