While the GL shading code makes it easy to do smooth shading by interpolating the light values at the vertices against their averaged normals, flat shading can make it easier to see what the actual survey data is.
You can also use the white saturation of the colours to indicate the slope of the polygonal surface, which also helps to interpret the ambiguous directions of all the surfaces.
