SurfaceFootprintReplacer

This transformer accepts any feature, except those with null geometries.

Output features with replaced shadow geometries.

Features with null geometries are rejected.

Overhead Shadow: The shadows are obtained from a light source directly above the features. The shadows will have a Z coordinate specified by the Elevation parameter.

Drop Shadow: The shadows are obtained from a light source located in a direction specified by the X, Y, Z parameters. The shadows will have a Z coordinate specified by the Elevation parameter.

Perpendicular Shadow: The shadows are obtained from a light source located in a direction specified by the X, Y, Z parameters, but are cast onto a plane perpendicular to the direction of the light source. Each feature's shadow is located near the original feature, so the shadows may not all lie on the same plane.

Coordinates representing the direction of the light source projecting the shadow. The light source is considered to be an infinite distance away.

The Z coordinate cannot be 0.

The value that will be used as the Z coordinate in the output shadow features. This parameter is not used when the Shadow Mode is Perpendicular Shadow.
