#1519: [raster] ST_MapAlgebraExpr : provide more keyword substitution
-------------------------+--------------------------------------------------
Reporter: strk | Owner: pracine
Type: enhancement | Status: new
Priority: medium | Milestone: PostGIS 2.0.0
Component: raster | Version: trunk
Keywords: |
-------------------------+--------------------------------------------------
In addition to the existing "rast" keyword substitution, which returns a
pixels' value, it would be useful to have another keyword expanding to the
pixel geographical location (a polygon) and maybe another couple for X and
Y informations.
We may be still in time for 2.0, as it's probably an easy and safe
addition.
