The very latest mapping technology is being used in the Nadi and Ba basins to produce extremely detailed digital terrain models as part of an ongoing effort to lessen the effects of floods in the area.

For the last two weeks an Island Hoppers helicopter fitted with Light Detection and Ranging (LIDAR) equipment has flown over the Nadi area scanning the ground with near infrared light to get the most detailed topographical data of the area ever recorded.

According to Litea Biukoto, from the Disaster Reduction Programme at the Secretariat of the Pacific Community’s Applied Geoscience and Technology Division (SPC SOPAC), having high resolution topographical information is essential for  producing detailed floodplain maps that can help the National Disaster Management Office, the Nadi Town Council, and other government agencies to plan development in the floodplain, provide guidance for infrastructure and building designs and improve flood preparedness and response.
