Unified Interior Regions

South Dakota

Surface water and groundwater provide important water supplies in South Dakota. Major rivers include the Big Sioux, James, Cheyenne, and Missouri Rivers. Key aquifers include the Dakota, Madison, Minnelusa, and Big Sioux aquifers. The Dakota Water Science Center has many studies that focus on these resources as well various other national and international studies.

Remote Sensing Phenology

Phenology is the study of plant and animal life cycles in relation to the seasons. EROS maintains a set of nine annual phenological metrics for the conterminous United States, all curated from satellite data. Taken together, the metrics represent a powerful tool for documenting life cycle trends and the impacts of climate change on ecosystems.

Eyes on Earth Episode 12 – Plant Health via Satellite (NDVI)

A farmer at the foot of a corn stalk can tell how well the plant is faring. That same farmer might survey his entire field for crop health. But assessing the health of crops or forests at regional, national, and international scales requires remote sensing, most often via satellite. In this episode of Eyes on Earth, we talk to Jesslyn Brown about the Normalized Difference

Eyes on Earth Episode 16 – Predictive Modeling

Land cover and land use across the United States are the culmination of a complex web of interwoven factors: Climate, landscape types, and economic factors among them. Remotely-sensed data from satellites like Landsat and a variety of other sources are useful for documenting and monitoring land cover and land use. When used alongside other data sources, however, remote

November 15, 2018

The mapping and classification of land use and land cover has long been a primary duty for the U.S. Geological Survey (USGS), and remotely-sensed data at the Earth Resources Observation and Science (EROS) Center has served as the backbone of the Survey’s modern efforts.

In recent years, two advancements in remote sensing emerged that promise to revolutionize the field.
