Currently, I am using: CREATE TABLE map2 AS( SELECT ST_MapAlgebraExpr(ST_MapAlgebraExpr(a.rast,1, '32BF', '((67.6499557495117-[rast])/67.6499557495117)'), 1, ST_MapAlgebraExpr(b.rast,1, '32BF', '((14052.134765265-[rast])/14052.134765265)'), 1, '([rast1] * 0.5) + ([rast2] * 0.3)::float', '32BF').* FROM density a, euclidean b );
But its not exporting correctly, and using .* returns as a syntax error. Can anyone show me where I'm going wrong with this?
