Why do we calibrate Landsat data? We spoke with Brian Markham, a key figure of Landsat calibration science for four decades. He said that it all comes down to this: “If we’re using a system to quantify changes on the Earth, we must make sure the system we’re using is not changing.”
Grasslands tend to get left out of conservation discussion. New research from the World Resources Institute maps how they’ve changed over the past 20 years.
Wildfires have been increasing in frequency and size across North America in recent years. British Columbia is no exception to that trend; more than 4% of the heavily-forested province has burned since 2017. In 2023, Canada saw its worst wildfire season in recorded history. These high intensity fires affect ecosystem health and local economies, as timber is a major industry in BC.
Looking at urban heat islands, researchers found that changing trends in vegetation influence land surface temperature in the Lower Mekong Delta cities.
South Korea is facing a water quality problem. Researchers Hyunglok Kim and Seongjun Lee from the Gwangju Institute of Science and Technology (GIST) embarked on developing a model to predict water quality indicators in near real-time.
With Landsat-based ET embedded in more and more water rights and conservation tools, Willardson and the Western States Water Council are eager to see Landsat Next with its higher spatial resolution, more frequent observations, and additional spectral bands, built and launched.
Ross Walter, from the Landsat Outreach Team, has turned a much used, but static, Landsat Spectral Band Comparison graphic into a dynamic, multifaceted tool that enables users to compare different sensors and output the comparison graphics they need.
