Depth perception analysis of LiDAR digital elevation model for low lying areas using delaunay triangulation algorithm

There are several ways to determine if low-lying regions are prone to flooding, one is to set threshold values that will serve as basis to determine if the area is below sea level, and then that area could be a flood prone area depending on the measured level. Another situation is that not all area situated below sea level is flood prone and vice-versa. In this study, threshold was used to serve as reference in processing LiDAR data to determine the condition of each region under data processing. The method provided in this study provided an efficient way in looking at particular map regions to identify the elevations based on the Delaunay Triangulation Technique. The said method also allows the determination the different levels under a particular region.
