• LIDAR data processing
• Topographic analysis
• Measuring the change

Using different RST parameters (tension, smoothing) topographic parameters can be estimated at various levels of detail and a multiscale analysis of terrain geometry can be performed.

  Animation: profile curvature and slope with changing tension/smoothing

  Profile curvature 2001 and 1995
•  
  Slope 2001 and 1995
•  
  Profile curvature at high tension/low smoothing captures the noise from the LIDAR sampling
(dune crests are orange).
•   Profile curvature at moderate tension and smoothing
  captures well the major features, especially the dune slip faces, profile curvature at low tension/high smoothing shows main dine sections only
