In order to improve the speed of terrain selection algorithm and minimize the sensitivity of the selection rules to reference error,derived from the meaning and property of entropy,the terrain entropy was defined based on the elevation information which was used to weigh the amount of information that the different terrain involved.Based on this,the algorithm of terrain selection based on terrain entropy was introduced.The simulation result shows the algorithm's performance is demonstrated well.
