The saddle is one of the most important terrain feature points,the extraction of saddles based on DEMs is of significance to digital terrain analysis.Nevertheless,owning to saddles' unique morphological characteristic,it has more difficulties in extracting saddles than any other terrain feature points.This paper presented an improved saddles extraction method based on runoff concentration simulation in DEM.Firstly,the ridge lines were extracted by runoff concentration simulation in DEM.Then,inversed DEM were derived through overturning original landform to extract catchment lines,which can automatically divide the terrain.Finally,the saddles were extracted from intersecting feature lines.The experiments in different study areas demonstrated that this improved method considered the topological relationship between the saddles and surrounding terrain features,overcoming the disadvantage that the neighborhood analysis cannot take consideration of the whole terrain change.And the accuracy of saddles extraction was improved.
