Hi,

Evalscript actually only overrides how layer is defined in Configurator and nothing else.

The instance ID is required always because it also serves as an user authentification. It is not possible to make a request to Sentinel Hub services without it. In the Python package you have to either pass it as a parameter or save it into package’s configuration file.

When using evalscript even the name of a layer still has to be specified. That is because evalscript won’t override the source of data (i.e. Sentinel-2 L1C, Sentinel-2 L2A, Sentinel-1, Landsat 8, …). It will only override the equation specifying what combination of bands will be returned.

Thanks for asking this, I hope this answer makes sense.

Thanks for the quick reply. It does make sense, it overrides the configurator layer equation.

I will make sure I understand by doing it.
