[postgis-users] Correct or wrong raster image loading

[Giannis Giakoumidakis]

Thanks for the anwser.

My raster is 390x279, so I use -t 390x279. I get no errors. I didn't understand from your asnwer, the rows in the table should have been more than 1 that it is now or it is correct like that?

The .sql I get before I use psql is this, in Notepad++:

BEGIN;
CREATE TABLE "public"."cc00h00m15s" ("rid" serial PRIMARY KEY,"rast" raster);
INSERT INTO "public"."cc00h00m15s" ("rast") VALUES ('0100000400DDC80B44AA83173FF2C80B44AA8317BF1986D9154421394032D1D677B4AE414000000000000000000000000000000000E6100000860117010400828282828282828282828282.......')::raster;
ANALYZE "public"."cc00h00m15s";
SELECT AddRasterConstraints('public','cc00h00m15s','rast',TRUE,TRUE,TRUE,TRUE,TRUE,TRUE,FALSE,TRUE,TRUE,TRUE,TRUE,TRUE);
END;

I don't know why in the sql editor of pgAdmin, the: VALUES ('0100000400DDC80B44AA83173FF2C80B44AA8317BF1986D9154421394032D1D677B4AE41400....') are missing.

What are the dimensions (width/height) of your raster?  I just tested
your raster2pgsql command string...

raster2pgsql -s 4236 -I -C -M *.tif -F -t 100x100 testtable

And it has no issues.  The generated table will only have 2 or 3 columns
(3 since you specified -F).  Each raster column will have one entry in
the raster_columns view.

You may wan to check the SQL generated from raster2pgsql instead of
piping directly to psql.  I'm guessing something went wrong in the
raster loading process.  Without additional information (error messages,
if any), we really can't say what is wrong.

What I get is a table that has only 3 columns (rid, rast, filename) and 1 row only (I thought -t would create many rows). Also, 12 constraints. Finally, 1 row in the "raster_columns" view, which contains all the details of the loaded raster.
