Abstract
NSPAS can readily quantify aggregate breakdown processes across a 0.02â¯m2 surface by accurately detecting 0.84â¯mm to 2.49â¯mm changes in surface topography. The methodology is advantageous to micro-scale (<1â¯cm2) studies that require a high number of accurate DEMs, because it will produce image pairs even when the target does not have contrasting surface features in shot, which can be a constraint for the automated technique Structure from Motion. This paper demonstrates how NSPAS is more suitable to assess erosion from slope forming materials that do not have a high content of large rocks (>2â¯mm) at the surface. With further development NSPASS has the capability to be used in many other types of geospatial investigations.
