Abstract

In the past few years,slope were generated using topographic details captured using Total Station before the existence of Geodetic Laser Scanner (GLS). Although this method can give very high accuracy of measurement for generating slope model; it is expensive, time consuming, does not cover large area and need a physical contact on hazardous area. With GLS, generating slope model can be carried out without direct contact with hazardous area. There is a need of rapid data acquisition for slope mapping studies. The time of data acquisition is very important forfast decision making at the critical study area. Therefore, this study reviews the capabilities of GLS in slope mapping study which involves semi-undulation and undulation study area. This paper concentrates on the development of GLS in surveying applications, the source of errors in GLS measurement and scanning resolution. GLS is very useful inslope mapping studies especially for the rapid decision making for response agencies. Keywords:mapping, slope, GLS, accuracy
