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.
