Abstract :
For the suitability towards the reconstruction of geomorphological sound surfaces using digital elevation models different methods as a weighted neighborhood member procedure, a ordinary kriging procedure, a gradient spline technique and a new modification of heat flow equation were tested. Round-off effects and effects of local noise-signal ratio were investigated
