Disaster Response & Mitigation

DISASTER RESPONSE & MITIGATION

Disasters such as Landslides, Cyclones, and Glacial Outbursts are devastated. Satellite Remote Sensing and Photogrammetry have a lot of limitations in Hilly areas which are much more prone to such disasters.In this condition, Airborne laser scanning is vital in assessing the extent of damage, providing rehabilitation measures and Planning for Re-development of Infrastructure.Etc. Airborne LiDAR is capable of obtaining the versatile Ground Elevation Profiles which is a vital information in all the stages of disaster management features can be extracted from the LiDAR point cloud accurately which will help for various analysis.Disaster management can be defined as the effective organization, direction and utilization of available counter-disaster resources, that there must be pre-disaster mitigation measure to avoid or reduce impact of disasters. Pre-disaster measures to prevent or mitigate disaster are called Risk Management

Disaster response planning and management is one of the most significant applications of LiDAR data, when situational awareness and accurate decisions are vitally important. LiDAR use in this realm encompasses everything from mapping vegetation that is prone to wildfires, to create an inventory of assets, to monitor structural damage after flood, landslide and earthquakes. Knowledge extracted from LiDAR data helps emergency responders efficiently plan disaster relief efforts to prevent property loss, reduce injuries, save lives and restore crucial utilities like water and electricity to affected communities.

Ideally, soon after a disaster, aircraft equipped with LiDAR sensors fly over affected areas to collect current data that is invaluable when planning an appropriate response. Once these data are processed, emergency responders use them for two main purposes: creating a visual map of the disaster area, and extracting important information about the area, such as determining safe locations for shelters, identifying downed power lines and locating areas that have a high risk of mudslides or flooding. LiDAR data also helps to assess risks, reduce vulnerabilities and create appropriate action plans before disasters strike.New LiDAR data processing techniques streamlines the overall geospatial workflow by enabling users to export results directly to the GIS platform for mapping applications and additional decision making. These benefits have led disaster management organizations to use LiDAR data as a source of information when mapping and making critical decisions.
