I’m trying to reproject S3 - OLCI so it would fit into the grid of S2 (e.g. one S3 pixel would contain 30x30 S2 pixels). (The result does not have to cover exactly the same area as S2)
- Subset the S3 data
- I chose same projection as my S2 data (epsg:32719)
- Uncheck ‘preserve’ resolution and choose
o ‘easting’ / ‘northing’ so it would fit into S2 grid
o ‘pixelSize’ to a 30 x S2 pixel size
The result fits into the S2 grid as expected and sometimes the pixels cover the right area but often is shifted towards X/ Y over several 300m pixels.
Any ideas what I do wrong?
I use the GUI SNAP version 6.0 with settings like http://forum.step.esa.int/uploads/default/original/2X/9/9bbd0d61a4a12f21fefc5e07e6164db5a13f0641.png
