“The Deltares Aqua Monitor is the first global-scale tool that shows at 30-m resolution where water is converted to land and vice versa. With assistance from Google Earth Engine, it analyzes satellite imagery from multiple Landsat missions, which observed Earth for more than three decades, on the fly.”

“The availability and accessibility of remotely sensed digital imagery obtained from Landsat satellites allow coastal scientist—and more importantly community members—the opportunity to map, evaluate and continuously monitor shoreline movement at regular intervals given the unprecedented pace of Arctic climate change.”

“You can launch a new satellite, but you can’t put something up in the past. Landsat will always be that historic record that new satellites can tie themselves to.”

“The issue of forest disturbance could not have been addressed without our analysis of Landsat Time-series Stacks”

“We knew that ice had been retreating from this region recently but now, thanks to a wealth of freely available satellite data, we know this has been occurring pervasively along the coastline for almost half a century.”

“As one of the longest data archives suitable for this purpose, Landsat data allows us to analyze coastal wetland change over time-periods that enable us to monitor long-term directional change in the extent of the world’s coastal ecosystems and distinguish them from natural fluctuations. Our work on tidal flats and global coastal wetland change would not be possible without free access to a long-term, spatially comprehensive dataset such as Landsat.”

“Now that the entire Landsat archive is freely available it has become economically feasible to monitor disturbance over large areas using satellite time series.”

“We’re happy to see that the Agribotix imaging system performs so well when compared to Landsat 8, one of the highest quality land imaging satellite systems…”
