[postgis-devel] [WKT Raster] ST_SetValue

[Paragon Corporation]

Pierre,

We haven't had a chance to test ST_SetValue, but its on our todo.

By the way -- the latest windows builds with it are up on the experimental
for those who want to try it.

Based on your naming, it sounds like the geometry value for the geometry
version, only takes a point.

We were thinking it would be really nice if it could take any kind of
geometry and color in any pixel that intersects the geometry.

That way you can do things like make statistical maps right in PostGIS like
a heatmap.  Not sure if that was along the lines of what George was thinking
as well.

I know it then doesn't quite follow the ST_Value pattern, but I think for
this case, its understandable to do it that way.

Just a thought and maybe you thought of it already.

Thanks,
Regina and Leo
