When making an empty raster, is there a way to control the direction of the
raster?
The starting point for the raster is upperleftx, upperlefty. So If I'm in the
southern hemisphere, the upperlefty value is a negative number, hence the grid
builds in a northerly direction
INSERT INTO dummy_rast(rid,rast)
VALUES(1, ST_MakeEmptyRaster(100, 100, 570344, -3781663, 1000, 1000, 0, 0,
3577));
If I change the width to -100 in the hope of reversing the direction, no luck...
INSERT INTO dummy_rast(rid,rast)
VALUES(1, ST_MakeEmptyRaster(100, -100, 570344, -3781663, 1000, 1000, 0, 0,
3577));
The blocksize_y doesn't accept negative numbers, and defaults according...
srid | scale_x | scale_y | blocksize_x | blocksize_y | num_bands | pixel_types
| nodata_values
------+---------+---------+-------------+-------------+-----------+-------------+---------------
3577 | 1000 | 1000 | 100 | 65436 | 1 | {8BUI}
| {NULL}
(1 row)
I understand the logic of why it's doing what it is.
Is there a way of making the grid build in a southerly direction if I'm in the
southern hemisphere?
