Quotes to Note
“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."
"The Landsat data record has been key to the Intertidal Extents Model methodology. Having such an extensive and dense time series of data has enabled us to partition the data into discrete tidal stages, and still be able to deal with issues such as cloud and cloud shadow—that is particularly crucial when dealing with the different conditions we encounter across the continent.”
"Satellite imagery can help us get the biggest bang for our buck by targeting conservation initiatives in a specific window of time at key locations. Landsat is the longest running Earth observation satellite system we have, and free access to this data enables researchers to look at the effects of seasonality, climate cycles, and long-term trends in land-use change."
“We show governments across the world that it makes financial sense to release broadly and openly the data that the taxpayer has already paid for. It will build your economy, it is certainly good for transparent government and, it is a boon for capacity building and education.”
"You may have heard me say this before, but I firmly believe there are few topics more fundamental to study than the workings of our planet. The earth sciences aim to unravel how the lithosphere, atmosphere, hydrosphere, and biosphere operate—and how they operate together. It is a science of synthesis. And it’s one that needs to move forward, both because of the great service the earth sciences perform for society and the understanding of world-shaping processes that they advance."
"We cannot do this project if the Landsat program doesn’t deliver this open data to the scientific community... We are benefiting from these long-term investments now."
"The long time span covered by the Landsat scenes allows us to determine long-term flow velocity trends. The high temporal resolution lets us analyze seasonal flow velocity variations of numerous outlet glaciers...The monitoring system provides a powerful tool to examine the flow velocity pattern throughout time and space, and we have detected an acceleration pattern for a number of outlet glaciers."
