## Workspace Method telsemStandalone

### Description

Stand-alone evaluation of the Telsem model.
This evaluates the Telsem land surface emissivity
model using the data from the provided atlas.
Since TELSEM atlases do not contain data for all locations
this function allows for nearest neighbor interpolation, which
can be enabled by setting the ``d_max`` GIN to a positive value.
This WSM throws a runtime error if the queried location is not
contained in the atlas or the distance of the neighboring cell
exceeds the given ``d_max`` value.
