Workspace Method InterpSurfaceEmissivityFieldIncLatLon

Description

Interpolation of surface emissivity specified as a function of
incidence angle, latitude and longitude.

The surface emissivity field has here three dimension, with
incidence angle as first/column dimension, latitude as second/row
dimension and longitude as third/page dimension. Grid names must
be set exactly to "Incidence angle", "Latitude" and
"Longitude". No extrapolation is allowed.

For 1D cases it is expected that the latitude and longitude grids
have both a length of 1. For 2D the same applies to the longitude
grid.

This method can be used together with e.g.
surfaceFlatSingleEmissivity.
