“We need to drive towards building sustainable cities and human settlements, and this depends on how well we measure these areas and how well we can predict the growth in all these cities in the future. I believe Earth observation and geospatial technologies give us the tools needed in order for us to grow in this direction.”

“The [Landsat-informed] World Settlement Footprint is a great example on how we can mobilize the data revolution for the benefits of all countries and cities, leaving no one behind, which is one of the leitmotifs of the 2030 agenda on sustainable development.”

“The availability of continuous data streams of high quality and free of charge satellite observations such as the Sentinels of the European Copernicus program and the Landsat missions, in combination with the emergence of automated methods for large data processing and data analytics, and the democratization of computing costs, offer unprecedented opportunities to efficiently monitor the changes and trends in urban development globally.”

"[With Landsat 8 and 9 together,] we get really great-quality data every eight days. That’s going to be a boon, especially for water quality applications.”

“We’re power users of Landsat.”

“Our research would not have been possible if it weren’t for decades of reliable Landsat data to help us look back in time. We hope these findings will encourage people to not only mitigate the effects of increased wildfire activity, but also to limit emissions and curb global warming.”

“I’d go to meetings and people were just jumping up and down because they had discovered another use for the data.”

“We are in this unique position where we have ice core records from these mountaintops, and Landsat has these detailed images of the glaciers, and if we combine those two data sets, we see clearly what is happening.” 

Landsat satellite imagery is ideal for gauging vegetation cover shifts because it supplies spectral data for surface areas of about 90 square meters – fine enough to track changing spectral signal patterns across large study areas. 

“Landsat has allowed managers to observe regional trends in kelp canopy area and biomass across more than 30 years. This is very valuable.”

"The tracking of over-irrigated areas for targeting irrigation advisory texts was completely dependent on Landsat TIR data."

"If you really want to have a long history of understanding any process in the Earth, Landsat is where you should go."
