More than a decade ago, Tom Loveland sat down to sketch out a few thoughts on land change and the Landsat archive. The archive was and remains rich with history, adding new observations of the entire planet every eight days. But at that point, Landsat-based land change research was about comparing points in time – this year versus five years ago, to 10 years ago, and so on.

The U.S. Geological Survey took a bold step toward documenting change across the landscape with the launch of the first Landsat satellite in 1972. Since then, the orbiters have collected nearly five decades of imagery.

Eyes on Earth is a podcast on remote sensing, Earth observation, land change and science, brought to you by the USGS Earth Resources Observation and Science (EROS) Center. In this episode, we learn how Landsat-based data products have been used to study forest change in California.

LCMAP land cover products provide information about land cover classification, including land cover classification information for a given area before and after change is detected by Continuous Change Detection and Classification. The five land cover products are built on broad Anderson Land Cover Classification System Level 1 based classes.

Below you'll find answers to common questions about USGS Land Change Monitoring, Assessment, and Projection (LCMAP).

The meandering shoreline is the claim to fame for the Midwestern tourist oasis that is Lake of the Ozarks in Central Missouri. The Missouri Division of Tourism’s website leads its page on the state’s most popular visitor destination by noting that the lake’s 1,100 miles of freshwater coast are more than even California has to offer.

The forests and rangelands of the Western U.S. face fire dangers on multiple fronts. The trees themselves provide fuel for wildfires, of course, but there are additional factors at play in this mountainous, forested stretch of land at the Idaho-Montana border.

Less than 15 miles separate the city of Plainfield from the nearby metropolis of Indianapolis, the capital of Indiana and the state’s largest urban center.
