What's the difference between a topographic map and a regular map?. Landforms are the natural shapes or features of the land.. There are many different types of landforms found on Earth.. What are Landforms?. Mountain. A mountain is a place on Earth’s surface that is much higher than the land around it.. YM . Wang, . S. . Holmes, J Saleh, XP Li . and D . Roman, . National Geodetic Survey. June 22 -25 WPGM 2010 Taipei, Taiwan. Abstract. The spherical harmonic expansion of the topographic gravitational potential has two major advantages over Newtonian integrals: it offers computational efficiency and facilitates spectral analysis of the Earth’s gravity field. The high degree harmonic expansion of the topography helps also in geoid computations.. exit ticket.
