Quotes to Note
"We have mapped then analyzed the area of forest converted each year to industrial oil palm and pulpwood plantations from 2001 to 2016, looking mainly at land under company management – that is, concessions. We use LANDSAT satellite imagery to monitor the annual expansion of plantations. We combine this information with annual maps of forest loss also derived using LANDSAT satellites by Matthew Hansen’s research group at the University of Maryland. The Hansen dataset, as we call it, produces very accurate tree loss maps over the humid tropics, and combined with a good forest mask, reveals where old-growth forests have been cleared...By combining our annual maps of plantations with this forest loss dataset, we can extract the area of forest converted each year to industrial plantations by producing companies. This is what we call company-driven deforestation."
"Landsat 8 is part of a revolution of how much remote sensing can do to track the polar areas."
“When you have Landsat you can actually show people how we are changing the face of the planet.”
“It’s being able to go back in time for the same location, with the same program, that’s given us a tremendous amount of really valuable information... With Landsat we can do that because the archive is so rich.”
“Landsat is everywhere, and has been for 40 years.”
"Within Australia, Earth Observation is so commonly used across all levels of government, industry and society that the minimum economic impact of Earth Observation from space-borne sensors alone is approximately $5.3 billion each year [Australian $; ~4.15B US$]."
“I don’t think anyone could have seen this before these new maps were developed.”
"Thanks to Landsat, we were able to dramatically improve our satellite base map in Google Earth and Google Maps on two separate occasions, first in 2013, and again in June 2016. Our most recent 15 meter-per-pixel global mosaic was made from over 1.5 million Landsat 7 and Landsat 8 images and forms the view of Earth you see across our mapping products for the first twelve zoom levels of the imagery basemap."
"Over the years, we’ve used the Landsat imagery to develop an incredibly accurate depiction of Earth and its changes over time, which we’ve published in Google Earth and Maps for use by billions of people worldwide."
"At Google, we use Landsat data on a daily basis."
"Landsat, a joint program of the U.S. Geological Survey (USGS) and NASA, offers an unparalleled record of our changing planet, with satellites that have been observing the Earth since 1972 to the present day."
"Landsat is the crown jewel of Earth Observation datasets—unique 40+ year archive."
