Abstract

Abstract

We study TERCOM algorithm in gravity matching and analyze its adaptability.The experimental result shows that this algorithm can do precise matching easily.There is a significant correlation between coordinates error and roughness.It is gradient variance.Roughness and gradient variance are good indices to select matching areas.
