Assessment on slope mapping using airborne laser scanning and terrestrial laser scanning
Khairul Farhanah Khairon1, Khairul Nizam Tahar2.
This study is about the evaluating the differences of two techniques of
Airborne Laser Scanning (ALS) and Terrestrial Laser Scanning (TLS),
by carried out an assessment on slope mapping. This study is carried by
assessing the Digital Terrain Model (DTM) of a slope in Habu, Cameron
Highland Pahang. The further slope assessment is done based on the
difference slope class using slope map and slope aspect by ALS technique
and TLS technique. These two techniques of data collection provide a threedimensional
data point. However, since both techniques is operating in a
different platform where the ALS is a kind of data collection from the air
platform while TLS is only based on the ground surface, there might be a
slight differences in data production even though the use of the same slope
is controlled. Hence, at the end of this study, the differences between these
two data collection of ALS and TLS could be compared.
