[postgis-users] IDW - RASTER - ST_InvDistWeight4ma

[caymo04]

Good morning everyone,

I need support about ST_InvDistWeight4ma.

Is it possible to do IDW to full band into the RASTER with only 8 pixels
with value?

I tried with:

UPDATE ch07.idwlpa SET rast=st_mapalgebra (rast,2,
                         'st_InvDistWeight4ma(double precision
[][][],integer[][],text[])'::regprocedure,'8BUI',NULL,NULL,1,2,'1');

But, the result is without IDW interpolation.

How can I do it with POSTGIS?
I would like to do IDW into POSTGIS.

Best regards and thanks a lot in advance.

Acaymo.
