Same bounding box, different output AWS/EOCloud


I noticed that when I request a square bounding box with a WCS request in Python from AWS, it expectedly returns a square image (17*17 pixels):

While when I use exactly the same WcsRequest to request exactly the same geometry from EOCloud (so only the source and a layer is different), the output is no longer a square image, but is a 13*15 pixels image.

Do you know why this happens? Shouldn’t both be the same given exactly the same inputs? In both cases I feed the bounding box with coordinates in WGS84.


EO Cloud’s system is our legacy system, designed 4 years ago and (almost) not updated since.
AWS (and CreoDIAS and Mundi) system has evolved in due time.
I imagine reprojection function improved a bit.
