Abstract

Lidar is a remote sensing technology that is developing and widely used today. This data has the advantage of having a very high spatial accuracy so that it is very supportive of mapping with detailed accuracy. There are various benefits of lidar data, one of which is for risk analysis of natural disasters. The purpose of this study is to use lidar data to analyze flood disasters in an area. The method uses information derived from the Lidar data, namely the Digital Surface Model (DSM) and the Digital Terrain Model (DTM), which results from ground and non-ground classification. From this data, topographical analysis is carried out, especially the river flow area and its influence on the surrounding area. The research location is the City of Mataram, Lombok, Indonesia. This location is a coastal area and the location through which the river flows into the sea. The results of the analysis of this study were compared with data on flood disasters that had occurred in that location as comparative data. The results showed that the analysis using Lidar data has excellent topographic accuracy as an approach in the analysis of flood disasters towards an area.
