I have encountered a bug while reprojecting an OLCI EFR scene which seems to be adding ghost pixels very far away from the scene center. I have noticed this for quite a number of scenes when attempting to reproject and wondering if this is a bug or that I am missing something.
It seems that turning off per-pixel geocoding (using the tie point grids) fixes this issue.

Script: (With per-pixel geo-coordinates enabled)
-> Subset (e.g. select Oa01 radiance)
-> Reproject (To Geographic Lat/Lon WGS84 or Auto UTM)
-> Write (BEAM-DIMAP)
Source image bounding box according to the source geo_coordinates.nc (the sci hub footprint also agrees with this)
Upper Left lon/lat (degrees): -160.42,-20.58
Lower Right lon/lat (degrees): -144.45,-34.05
Output bounding box (via gdal):
Upper Left (-168.8932150, -18.7364568) (168d53’35.57"W, 18d44’11.24"S)
Lower Right ( 160.5098426, -49.0349038) (160d30’35.43"E, 49d 2’ 5.65"S)
If anyone else has encountered this issue and guidance would be appreciated.
