USGS Ups Ease of Use for Landsat Data

The USGS has begun production of higher-level (more highly processed) Landsat data products to help advance land surface change studies. One such product is Landsat surface reflectance data.

Surface reflectance data products approximate what a sensor held just above the Earth's surface would measure, if conditions were ideal. The precise removal of atmospheric artifacts increases the consistency and comparability between images of the Earth's surface taken at different times of the year and different times of the day.
