Description

Hello,

I am trying to orthorectify a Pleiades images with OTB library and i have some difficult to do this on OTB 6.6.0. My output is smallest than expected (31 000 ko rather than 3 Go). However on OTB 6.4.0 the process works fine.

My full process bellow.

Steps to reproduce

SET DEM=DEM
SET OUT=OUTFOLDER
SET GEOID=GEOID
SET EPSG=EPSG
SET PAN1=PANCHROMATIQUE_TIFF_1
SET PAN2=PANCHROMATIQUE_TIFF_2
SET MS=MULTISPECTRAL_TIFF
SET IMGREF=IMAGE_REFERENCE (that is a .vrt)
