“Landsat has been extremely beneficial as it allowed us to frequently evaluate the movement of the shoreline based on data gleaned from one consistent source over the duration of the study period. Further, the continued use of Landsat will allow for ongoing monitoring of the coastline in this region to ensure that potential infrastructural improvements are sustainable based on projections of near-term climate change.”

“Landsat provides an unparalleled record of how terrestrial Earth has changed since the early 1970s, closely coinciding with the beginning of rapid environmental change. It provides important historical context for the current state of land cover and land use and provides a reference for identifying abnormal types and rates of change.”

“While many previous studies have reported ongoing ice shelf thinning around Antarctica since the 1990s, we didn’t previously know that a lot of it started around then.”

“With the full Landsat record available, we can finally look at really big problems, like the global carbon cycle.”

“It’s a fundamental resource for the Australian community. It’s used at local government level, state government level, and national levels. It’s our most important Earth-observing satellite with out a question in my mind.”

“Many people have no idea how Earth imagery has improved their daily lives as it has become integrated into modern technologies. Like GPS and weather data, information from Landsat is woven into the fabric of our economy and society.”

“[T]he pivotal aspect of the Landsat mission is the acquisition and curation of the most comprehensive and longest uninterrupted cross-calibrated EO data record ever gathered, with ensured continuity, and with ongoing efforts to consistently reprocess the entire image archive to incorporate cutting-edge advances in data preprocessing, which are then distributed as ‘collections’.”

“A sizable portion of our greenhouse gas contribution to the atmosphere comes from land use. And having Landsat data to look back to the 1970s, from there to now, you can then calculate or approximate year-by-year what that contribution is, and that’s extremely important.”
