Satellite imagery vegetation deforestation.

Landviewer s comparison slider can be useful in visualizing the differences between them and eyeball estimating the scale of deforestation or any other damage. The big issue is tracking deforestation in tropical countries says pontus olofsson a research assistant professor in boson university s earth and environment department. Pinpointing these locations is essential it s where cargill is taking action on the ground to prevent further deforestation and restore cocoa production landscapes. Learn about deforestation rates and other land use practices forest fires forest communities biodiversity and much more.

Satellite images show that a small minority of farmers are responsible for most of the deforestation in brazil. Satellite maps of forests in new england and across the world are allowing experts to observe how they are changing over time and in doing so measure deforestation. By carefully measuring the wavelengths and intensity of visible and near infrared light reflected by the land surface back up into space scientists use an algorithm called a 8220. Trends of amazon rainforest deforestation can be best observed with multi temporal analysis of satellite imagery i e.

The big issue is tracking deforestation in tropical countries says pontus olofsson a research assistant professor in boson university s earth and environment department. These images help our team identify places where forests and other sensitive ecosystems have been degraded or where intact forests remain in proximity to cocoa farms. The vegetation turns most green and abundant during the rainy monsoon months but also becomes hard to observe from optical satellite imagery due to the accompanying heavy cloud cover. Cleared areas tan spread from roads cut through the forest green a pattern of deforestation typical in rondonia.
