Test data
Sample image A from the WCS KISS dataset
Sample image B from the WCS KISS dataset
Image A is an exact SUBSET of image B
Images are of type "pixel is area". The pixel centers show in this image
Extents of the test images
1) In first case the raster images are somewhere in Chine where the longitude is greater than 90. Polygons which contain completely all the pixels are in the PostGIS EWKT format:
Image A: SRID:4326;POLYGON (( 115 30, 115 33, 117 33, 117 30, 115 30 ))
Image B: SRID:4326;POLYGON (( 114 29, 114 34, 118 34, 118 29, 114 29 ))
Image A has width=2 and height=3 and it can be constructed from an array: [Red,Red,Green,Green,Blue,Blue]
Image B has width=4 and height=5 and can be constructed from an array: [Grey,Grey,Grey,Grey,Grey,Red,Red,Grey,Grey,Green,Green,Grey,Grey,Blue,Blue,Grey,Grey,Grey,Grey,Grey]
