Eyes on Earth Episode 4 - Cataloging Earth Observation Satellites
Earth observation used to be the province of a handful of countries with satellite technology. Today, hundreds of satellites built all over the world are launched every year. This episode of Eyes on Earth talks about the explosive growth in the civilian and commercial remote sensing and EROS’ role in it.
Guide to Digital Imagery Spatial Resolution
Spatial Resolution is more than simply Ground Sample Distance (GSD). This guide, prepared for the USGS by Innovatve Imaging and Research Corporation (I2R)
Landsat's Calibration and Validation
Engineers and scientists from both Landsat and Sentinel missions are working together to calibrate observation data and validate its quality to improve the science using these resources.
Every Pixel - Landsat's Sensors
On board Landsat 8 are two sensors that capture data about earth's surface. Here is an explanation of the instruments that capture every pixel.
Every Pixel - Processing Data
Once the ground stations receive data from Landsat, there's still a lot of processing to make every pixel usable. Here's an overview of some of that work.
GOES-16 and Landsat 8
These infrared satellite images were collected on May 24, 2019 over the Washington, D.C. area.
The larger image comes from the National Oceanic and Atmospheric Administration (NOAA) Geostationary Operational Environmental Satellite (GOES) 16, a geostationary spacecraft at 22,500 miles. The near infrared image has a resolution of 1 kilometer per pixel. The smaller
