Slope Risk Assessment from Geospatial Data

Slope risk assessment is important in any projects to avoid any danger occurrences that
could lead to deaths and fatalities such as landslide. Generally, the slope risk
assessment is done on site by taking the elevation and contour data for slope stability
analysis. There are two common methods in determining the slope risk which are finite
element method and limit equilibrium method. However, both methods required to
obtained data on site which consume time and money. More time and money would
be spent if the site is further from the workplace. Therefore, the slope risk assessment
method through geospatial analysis might be the solution for this problem. LiDAR is
an effective way to obtained data. LiDAR uses remote sensing to obtain data without
going to the site. Some studies have even shown that LiDAR is the most precise data
and there are many case studies have been conducted based on LiDAR data. The
analysis of the slope risk assessment can be conducted from LiDAR data in ArcGIS in
spatial analytics. In this project, the area covered is at Cameron Highlands.
