Landsat's Role in Agriculture and Food Security
Worldwide, millions of people are helped by Landsat-data-based decisions that impact food and water management. Food and farming organizations rely on the unbiased, accurate and timely information provided by Landsat satellites. The data enable people to analyze the health and vigor of crops as they mature over the growing season; the needs of specific fields for fertilizer, irrigation and rotation; planted acreage to forecast crop production and fight crop insurance fraud; how much water is used in irrigation; and the impacts of drought.
Landsat Impedes Crop Insurance Fraud
With unbiased Landsat imagery as evidence, the U.S. Court of Appeals for the 9th Circuit affirmed an earlier jury-conviction of a northern California farmer found guilty on 16 counts of filing false federal crop insurance claims—scheming the government out of $410, 372.
Using Landsat 8 to Locate Fires in Indonesia
In June, air pollution over Singapore and Malaysia spiked as forests in neighboring Sumatra (Indonesia) burned. Using NASA’s daily fire alerts and official national maps, the fires were located in the vicinity of oil palm and acacia tree plantations. However, the coarse resolution of the fire alerts coupled with outdated national maps, made it hard to establish culpability.
Landsat Images Provide the Gold Standard for New Earth Applications
Images from Landsat satellites provided free to the public by the Department of the Interior’s U.S. Geological Survey were the starting points for “a new breakthrough” reported today by Time and announced
New Maps Provide Crucial Information for Water Managers
For the first time, U.S. Geological Survey scientists have mapped long-term average evapotranspiration rates across the continental United States—a crucial tool for water managers and planners because of the huge
What is the Economic Value of Satellite Imagery?
Does remote-sensing information, such as that from Landsat and similar Earth-observing satellites, provide economic benefits to society, and can this value be estimated? Using satellite data for northeastern Iowa, U.S. Geological Survey scientists modeled the relations among land uses, agricultural production, and dynamic nitrate (NO3–) contamination of aquifers.
Landsat Adds Tremendous Value to Decision-Making and Bottom Line
Dr. Stephanie Hulina, President of Geospatial Data Analysis Corporation (GDA Corp) discusses how access to free Landsat imagery from USGS enables her business to provide value-added products to her company’s clients. The long-term continuity of the Landsat mission is essential to her company’s ability to maintain a competitive edge in today’s global economy.
