Eolian deformation detection and modeling using airborne laser altimetry

Monitoring of landscapes or sea bottoms by means of laser altimetry or multibeam results in huge amount of data covering the same area in different epochs. Often stable benchmarks are not available in the area covered. We propose a geodetic/geostatistical method to analyze possible deformations in such area out of time series of data. The method is used for a deformation analysis of six consecutive years of laser data covering a dune section on the south-west coast of the island of Texel, the Netherlands.
