Error using l1bextract_safe_nc to extract MERIS 4th SAFE data

[andrew.meredith]

I note the help indicates l1bextract_safe_nc is for extracting OLCI L1B, but was hoping it would also work with MERIS L1B SAFE files. Unfortunately it doesn't, but it would be great if it did. I get the following error trying to extract data from the latest MERIS RR 4th reprocessing data container:

$l1bextract_safe_nc -v --north=31.05 --south=24.18 --east=-79.02 --west=-87.97 EN1_MDSI_MER_RR__1P_20110101T153248_20110101T161618_046218_0083_20180816T074414_0100.SEN3/ ./

north=31.05 south=24.18 west=-87.97 east=-79.02

Locating pixel/line range ...
Error locating pixel/line range to extract.
No extract; lonlat2pixline status = 255

lonlat2pixline fails if given the geo_coordinates.nc file but works if I give it the xfdumanifest.xml

What tag of OCSSW are you using?

[andrew.meredith]

I tried both V2021.2 and T2021.19

Please try

Code: Select all

l1bextract_safe_nc -v --spixl 40 --epixl 766 --sline 2363 --eline 3123 EN1_MDSI_MER_RR__1P_20110101T153248_20110101T161618_046218_0083_20180816T074414_0100.SEN3/ ./

That worked.
