[GRASS-dev] lib/gis/band_reference.c ?

[Stefan Blumentrath]

Thanks Maris for the reply.

I could not find that option in r.support.

i.band allows to add e.g. S2_12 as band reference, but nothing custom. And the g.bands manual says that user-defined band references are not yet supported. 

Has that been added recently? Or would I have to edit the bands json file of the system first?

My system is:
g.version -ger
version=8.0.dev
date=2021
revision=dd9d36830
build_date=2021-07-08
build_platform=x86_64-pc-linux-gnu
build_off_t_size=8
libgis_revision=d2a5e8e8f
libgis_date=2021-06-16T04:05:21+00:00
proj=7.0.0
gdal=3.0.4
geos=3.8.0
sqlite=3.22.0

Cheers
Stefan

GRASS supports arbitrary band reference names. Just make them unique enough to not mix together apples with oranges by accident (e.g. "min"
is a bad idea, "min_t_c" is better; "NDVI" would work; "elevation" – bad, "elevation_m" – better).
You can set band references after import with r.support module.

Have fun,
Māris.
