Integrated Land Change Monitoring

Satellite images that have been continuously acquired for many decades represent a unique record of our planet’s surface. At EROS, we analyze satellite and other data to determine not only how the Earth’s land cover has changed over time, but also the driving forces behind the changes. Understanding the how and why of past land cover and land use change makes it possible to more accura

USGS EROS Archive - AVHRR Normalized Difference Vegetation Index (NDVI) Composites

Weekly and biweekly NDVI composites based on 1-km AVHRR data (1989 to 2019). To all users of AVHRR composites. The NOAA 19 satellite which currently supports the AVHRR sensor has been degrading in orbit to the point where the nadir view is on the day night terminator within its orbit.

USGS EROS Archive - Advanced Very High Resolution Radiometer (AVHRR) - Orbital Pass Generation and Stitching

Orbital Pass Generation Nearly 45,000 individual observations were acquired during the first 30 months of this project. The number of individual scenes and overall data volume, an estimated 4.0 terabytes, are large by contemporary standards. As a result a new process was developed to improve data management.
