Thanks to the rollout of free, high-resolution satellite imagery, the job of monitoring deforestation in tropical forests just got a lot easier. Last year Norway’s Ministry of Climate and Environment entered into a contract with three well-established satellite monitoring technology groups: Kongsberg Satellite Services (KSAT), Airbus and Planet. Planet uses satellites to capture images of the Earth on a daily basis. The best images from a given month are stitched together into a seamless, cloudless, mosaic. These monthly mosaics give users a clear picture of where deforestation is happening and how it has progressed over time. Now, anyone with an internet connection can view these mosaic images via the Global Forest Watch (GFW) website. Tech-savvy users can also download data directly from Planet for research or to create their own maps.

The Monitoring of the…This article was originally published on Mongabay Läs mer
