FORCE UDF - "force_pixel" returning "BLEND" in sensors array when using multiple sensors?

[vudongpham]

Hi David,

When executing FORCE (3.7.12) UDF (python) with more than one sensor, the sensors array returns list of ['BLEND', 'BLEND', ...]. However, I find it sometime helpful to have the exact sensor information of each observation. Is it too complicated to implement this?

Hi Dong,

is this the UDF module, or the TSA module?

Hi David,

I test in the TSA module.

OK thanks, I will have a look. It is certainly possible, but not straightforward.

Hi Dong,

this is now implemented in dev.

The first part is always the python UDF, the second one is R. Both with:
