With an estimated 14.8 million hectares (36.6 million acres, or 57,150 square miles) of peatland across Indonesia, a balance between cost and effectiveness was an important factor in selecting the winning proposal. Supiandi said the cost of mapping peatlands using the winning method would be $1 to $6 per hectare (40 cents to $2.43 per acre). “That’s why we agreed to declare the team as the winner.” “While the cost is relatively higher, its accuracy is better,” he told reporters after the announcement. Supiandi Sabiham, co-chair of the competition’s scientific advisory board, said the combination of these methods gave the IPMT the edge over the other finalists, especially on accuracy. However, it was the team’s decision to combine the various methods that was hailed by the judges. Some of the technologies and methods are not new, such as lidar, which was also proposed by other finalists as well as the Indonesian government. “Our methodology can support work to acquire the topographic elevation data on the country’s peatland, including dome-shaped peatland, that can be used to understand the groundwater level and other hydrological purposes,” said Bambang Setiadi, a member of the team from the BPPT, who is also chairman of Indonesia’s National Research Council. Finally, to accurately estimate peat thickness, the team used on-the-ground measurements. The team then used lidar to calibrate and verify the results from WorldDEM.

The team started off with German radar technology, called WorldDEM, that uses satellite imagery to model terrain at a 10-meter (33-foot) resolution, as well as imagery from the Sentinel series of Earth-observation satellites. The IPMT proposal combines satellite-based technologies and the airborne high-resolution mapping technique known as lidar - which involves beaming laser pulses at the ground from a plane and recording the reflected rays - with on-the-ground measurements. The BIG will have two years to fully adapt their methodology into the new peat-mapping standard, although some government agencies are clamoring to start adopting the system immediately. The winner, the International Peat Mapping Team (IPMT), boasts members from Germany’s Remote Sensing Solutions GmbH (RSS), Indonesia’s state-funded Agency for the Assessment and Application of Technology (BPPT), and Sriwijaya University in South Sumatra province. “The BIG is pleased and excited that the prize has produced the best method for mapping peatland that combines accuracy, affordability and timeliness to support the BIG’s work in mapping and providing geospatial data and information,” agency chief Hasanuddin Zainal Abidin said at the announcement in Jakarta. 2 to coincide with World Wetlands Day, two years after Indonesia’s Geospatial Information Agency (BIG) launched it to select a mapping proposal to serve as the standard for surveying the country’s peatlands. The winner of the $1 million Indonesian Peat Prize, funded by the David and Lucile Packard Foundation, was announced Feb. JAKARTA - A team of scientists from Indonesia, Germany and the Netherlands has won a competition two years in the making to come up with a fast, accurate and cost-effective way to map Indonesia’s vast tropical peatlands - an all-important carbon sink that the government wants to conserve. Indonesia will have two years to fully adapt the winning methodology into the new peat-mapping standard, although some government agencies are clamoring to start adopting the system immediately.The judges praise the winning methodology’s versatility, speediness and accuracy in mapping peatlands.A team of scientists from Indonesia, Germany and the Netherlands has won the Indonesian Peat Prize for coming up with a fast, accurate and cost-effective way to map Indonesia’s vast tropical peatlands.
