Below the roughening transition, crystal surfaces have macroscopic plateaus, facets, whose evolution is driven by the microscale dynamics of steps. A long-standing puzzle was how to reconcile discrete...
HEIGHT TEXTURE OF LOW VEGETATION IN AIRBORNE LASER SCANNER DATA AND ITS POTENTIAL FOR DTM CORRECTION
airborne laser scanning vegetation texture DEM/DTM correction
font style='font-size:12px;'>
2015/8/13
The influence of low vegetation on laser scanning and its disturbing effect (a systematic positive height shift) during DTM generation
is well recognized. Based on our experience in a previous study...
