I have successfully created a PostGIS raster (I am using PostgreSQL 9.1 32bit on Windows 7 64bit with raster 2.0 extension) and updated those pixels that have specific spot heights. The raster is a single band 32BF raster.
What I wish to now do is to use those spot heights to create an elevation raster layer via which all NoDataValued pixels have an elevation set that is interpreted from the spot heights around it. Has anyone any suggestions as to how this can be done by PostGIS's ST_Raster? (ST_MapAlgebra perhaps etc?) regards Simon -- Holder of "2011 Oracle Spatial Excellence Award for Education and Research."
