The result I got from processing Landsat 8 with l2gen has weird edge(as fig.1), seems the land mask isn't very good.

fig1:

fig2 is processed by ACOLITTE, which is normal

Any idea?

Thanks a lot.

The default landmask is indeed quite coarse (~500m) relative to the nominal 30m resolution of OLI.
You can run l2gen with land=$OCDATAROOT/common/landmask_null.dat and/or maskland=0
