Validation of grid-based surface reconstruction techniques applied to digital elevation models including the Shuttle Radar Topographic Mission

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-of...

Summary: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.
