Philippine Disaster Reduction Planners Using LiDAR

The Philippines is one of the most disaster-prone countries in the world. Its location in the Pacific places it on tectonic plates, making it vulnerable to earthquakes, as well as tropical cyclones and heavy rain.

Over the years, various geo-hazard maps have been issued showing fault lines and flood zones – areas where disasters could happen, but the maps the national government recently gave officials of the 16 municipalities in Metro Manila indicate much more detailed analysis of the potential effects of ground-shaking from earthquakes, wind damage from cyclones and flooding from heavy rain. These maps were derived from LiDAR surveys that were conducted in these areas, according to an article in the Voice of America.

The risk analysis project that led to the creation of the maps and the database was a collaboration of the Australian and Philippine governments. Australia Agency for International Development funded it with $5.4 million. Interesting.

  1. The LiDAR DREAM project that is carried out at the University of the Philippines in Quezon City is covering the 18 larges river basins of the Philippines about one third of the country or 100,000 square kilometer) with dense LiDAR (2 – 4 pulses / square meter) in order to create detailed flood maps for these regions. This endavour using three airplanes flying an Optech Gemini, Pegasus, and Aquarius is carried out by local staff under the guidance of Prof. E. Paringit who has set up an impressive operation at the university. As fat as I know this data will also be repurposed for other tasks such as forest management and geo-hazard mapping. Here are <a href=some pictures taken during my visits there.
