Satellite Imagery Vegetation Deforestation

Explore the state of forests worldwide by analyzing tree cover change on gfw s interactive global forest map using satellite data.

Satellite imagery vegetation deforestation.

Approach import images features. 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. In an effort to monitor major fluctuations in vegetation and understand how they affect the environment scientist use satellite remote sensors to measure and map the density of green vegetation over the earth. The big issue is tracking deforestation in tropical countries says pontus olofsson a research assistant professor in boson university s earth and environment department.

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

Cleared areas tan spread from roads cut through the forest green a pattern of deforestation typical in rondonia. By comparing two images of same forest taken at different times. Import the modis 250m pixel 16 day composite vegetation indices dataset. 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.

Learn about deforestation rates and other land use practices forest fires forest communities biodiversity and much more. 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. 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. Satellite images show that a small minority of farmers are responsible for most of the deforestation in brazil.
