Comment(by dustymugs):
No. That is incorrect. What versions (and revisions) of GDAL and PostGIS
are you using? I created a test transforming from 4326 to 3844
{{{
SELECT rid, (ST_Metadata(rast)).* FROM (
(
SELECT
1 AS rid,
ST_AddBand(
ST_MakeEmptyRaster(1, 1, 24.818115, 45.822675, 0.01, 0.01,
0, 0, 4326),
1, '8BUI', 1
) AS rast
) UNION ALL (
SELECT
2 AS rid,
ST_Transform(
ST_AddBand(
ST_MakeEmptyRaster(1, 1, 24.818115, 45.822675,
0.01, 0.01, 0, 0, 4326),
1, '8BUI', 1
),
3844
) AS rast
)
) AS foo;
}}}
If you run the SQL above, the results should be similar to:
{{{
rid;upperleftx;upperlefty;width;height;scalex;scaley;skewx;skewy;srid;numbands
1;24.818115;45.822675;1;1;0.01;0.01;0;0;4326;1
2;485990.139598202;481453.235469657;1;1;958.718116254953;-958.718116254953;0;0;3844;1
}}}
The results above are from a machine running GDAL svn-trunk !r23215 and
PostGIS svn-trunk r7964.
