Method Geography.Position()->approx_height()

Method approx_height

float Geography.Position()->approx_height()

Description

Returns a very crude approximation of where the ground level is at the current position, compared against the ellipsoid shell. WGS-84 is assumed, but the approximation is so bad that it doesn't matter which of the standard ellipsoids is used.
