Note:
Properties shown in RED are mandatory.
Algorithm
The slope and aspect algorithm to use
Altitude
The altitude of the light, in degrees between 90 (vertical) and 0 (horizontal), as a simple value, or as an expression, eg '43.2' or '57.296*altitude#' (the default value is 45.0)
Azimuth
The azimuth of the light, in degrees clockwise from north, as a simple value, or as an expression, eg '45.0' or '57.296*azimuth#' (the default value is 315.0)
Combined
Should the shaded relief map be created using a combination of slope and oblique shading?
Exaggeration
The exaggeration factor to apply to vertical values, as a simple value, or as an expression, eg '10' or '2*_MaxGridVal#' (the default value is 1.0)
Z ratio
The ratio between the vertical units and the horizontal units, as a simple value, or as an expression, eg '2.54' or '57.296*RadiansToMetres#' (the default value is 1.0)
