USD$2 Million LiDAR Launched by 5Cs – first for the Caribbean


The Caribbean Community Climate Change Centre (CCCCC) through the USAID-funded Climate Change Adaptation Program (USAID CCAP) on Monday 3rd December 2018 launched a US$2 million Light Detection and Ranging (LiDAR) System which will significantly boost the Caribbean’s ability to limit the ravages of climate change by improving its capability to monitor and plan for physical changes to the land and marine environments.

LIDAR, which stands for Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure ranges (variable distances) to the Earth. The equipment principally consists of a laser, a scanner, and a specialized GPS receiver. Airplanes and helicopters are the most commonly used platforms for acquiring LIDAR data over broad areas. Two types of LIDAR are topographic and bathymetric. Topographic LIDAR typically uses a near-infrared laser to map the land, while bathymetric lidar uses water-penetrating green light to also measure seafloor and riverbed elevations. LIDAR systems allow scientists and mapping professionals to examine both natural and manmade environments with accuracy, precision, and flexibility.

The purchase of the LiDAR system was made possible through funds provided by the Barbados-based USAID Eastern and Southern Caribbean Office through the 5Cs executed Climate Change Adaptation Program (USAID CCAP).

The use of an airborne LiDAR is the result of a collaboration with Maya Island Air (MIA), a locally-owned Belizean airline company. These critical developments also influenced the Caribbean Development Bank and the Government of Italy to provide financial support for the LiDAR system, which is soon to become operational in a region-wide exercise to map some 10,000 square miles of vulnerable coastal areas in the region.

The technology is capable of simultaneously gathering topographic and bathymetric (depth of the seafloor) data, which are to be used to provide detailed information of the region’s coastal areas, reefs and seafloor to produce flood and inundation maps and other products.

With a brand new Cessna aircraft fully customised to fly LiDAR missions, the partnership between the 5Cs and Maya Island Air also represents a new era of public-private partnerships and corporate social responsibility for the benefit of resilience building to the impacts of climate change in the Caribbean.

In addition to the LiDAR, five data buoys have been added to the regional Coral Reef Early Warning System (CREWS) network, and 50 Automatic Weather Stations (AWS) have been added to the regional climate and weather monitoring and data collection efforts in the Eastern and Southern Caribbean.

The acquisition of an Airborne LiDAR system by the Caribbean Community Climate Change Centre – also known as the 5Cs – is possibly the most significant achievement for data capture in the Caribbean. For decades, countries of the region have clamoured for LiDAR produced data the high cost all but prohibited its application; and the use of  LiDAR was made more difficult since such services had to be sourced from outside the region, adding to costs. At the same time, the requirement for more accurate data to provide evidence of climate change impacts has grown and is rapidly becoming the standard for climate financing.

The project has also provided a computer server that will enhance the input, processing and sharing of the vast amount of data generated from the equipment acquired under the project. The information will ensure that the CCCCC, its partners and regional Universities are able to provide accurate and country-specific climate and climate change data to help countries improve their countries abilities to protect their citizens from the effects of climate change.
