Quotes to Note
"What should be done with the old bird?"
"[T]he case for open data is more than proven by Landsat and Copernicus. Many innovative applications using these datasets are the dividends that benefit the taxpayer."
"The Landsat collection 1 datasets represent a milestone in remote sensing science, with comparatively stable radiometric calibration and atmospheric correction."
“The Landsat archive enables us to develop products that tackle problems and address issues at a continental scale. For a country the size of Australia, this would simply not be possible without free and open access to the full time-series that the Landsat archive provides.”
"I am a big fan of Landsat 8 satellite images as a resource when making maps."
“The community was very vocal regarding the value of a free and open data policy.”
“You can see the changes of your orchard over time & over space, and by measuring the canopy temperature [with Landsat] you can see whether the canopy is in balance with the rest of the environment around the trees.”
“As a researcher with a limited budget, using the Landsat data for free made this project possible. The global geographic range together with free availability ensures that our study could potentially be repeated in other countries.”
"Our mapping techniques build on the historical Landsat record to provide highly needed information on regional scale and this helps in evaluating subtle changes in mangroves over a long period of time (trends) and to detect sudden changes due to natural catastrophes or dramatic anthropogenic impacts... [and] Thanks to the increased abundance of Landsat satellite images, it is becoming progressively easier to collect available images of mangrove habitats captured at low tide and high tide."
"Global Forest Watch’s ability to take advantage of Landsat imagery to produce a global forest monitoring platform highlights why remote sensing has become such a revolutionary technology. The imagery has achieved a state-of-the-art quality—NASA’s Landsat data is delivered in 30x30meter squares and has been for the past 40 years. Beyond this, it has been made radically accessible. Since 2008, anyone has been able to view and download the data from the United States Geological Survey (USGS) website free of charge, which has made satellite imagery a primary tool for forest and land cover monitoring. Without it, GFW would not be possible."
"Landsat, now one of the largest and most powerful tranches of Earth-science data, is an invaluable scientific resource."
"Without the free and open Landsat data policy, a lot of commercial applications wouldn’t be feasible and a lot of commercial companies—including GDA—would be very different than they are."
