Lai_retrieve_processing.py Error

Biophysical Indicators Processor

Hi,

Since I’ve the updated to Version 1.8.3 the manual execution lai_retrieve_processing.py only produces NDVI and RVI-Products but stopped working for LAI, FCOVER, FAPAR after excuting the following line:

““lai_retrieve_processing.py” --input /mnt/archive/maccs_def/at/l2a//S2B_MSIL2A_20170807T101029_N0205_R022_T33UUQ_20170807T101349.SAFE/S2B_OPER_SSC_L2VALD_33UUQ____20170807.HDR --res 10 --outdir /mnt/archive/temp/test/33UUQ/ --rsrcfg /usr/share/sen2agri/rsr_cfg.txt --laiBandsCfg /usr/share/sen2agri/Lai_Bands_Cfgs_Belcam.cfg --tileid 33UUQ --modelsfolder /mnt/archive/temp/test_lai --generatemodel YES --generatemonodate YES --genreprocessedlai NO --genfittedlai NO --useinra YES --fcover YES --fapar YES --siteid 2”

According to the attached application-log (Line 163,164) the problem is related to a missing mandatory input parameter (angles) of the Function: otbcli BVLaiNewProcessor

Does anybody encountered the same issue or knows how to solve the problem?
Thanks

Yes I think you need to install gdal version >= 2 and follow up the intructions made by Cosmin here:

Hi. Was anyone ever able to solve this issue? I tried executing it myself manually and got the same error. It looks like BVLaiNewProcessor requires it as an argument but its never specified in lai_retrieve_processing.py. My guess is OTB was upgraded to include this new parameter and the Sen4Cap installation doesn’t lock down the OTB version.

Here is the line of code its failing on:
runCmd([getScriptNameOSDepending(“otbcli”), “BVLaiNewProcessor”, appLocation,
“-xml”, xml,
“-outlai”, curOutLaiImg,
“-laicfgs”, args.laiBandsCfg])

Clearly the --angles argument is not being passed in, but I could be missing something.

Here’s the output of what lai_retrieve_processing.py is trying to do:
