Esta herramienta ayudaría mucho en los proyectos de carreteras. Ojalá se animen @zachri.jensen, @Paolo_Emilio_Serra1 u algún otro profesional.  
Les adjunto la superficie de trabajo.  
La idea es obtener la ruta de pendiente constante. bajada o subida. conocido como la línea de ceros, o línea gradiente.
