Land change is a signature activity of human civilization. Since the dawn of history, people have purposefully converted natural landscapes to human-dominated areas. Typical motivations for land change are cultivation (e.g. slash-and-burn fields, rice paddies, modern farms); occupation (villages, cities, housing developments); and other cultural and economic pursuits (roads, schools, airports).

A recent White House-led assessment found that Landsat is among the Nation’s most critical Earth observing systems, second only to GPS and weather. A new USGS study, Landsat and Water — Case Studies of the Uses and Benefits of Landsat Imagery in Water Resources, provides examples of why Landsat is so valuable.

Jul 23, 2014Landsat’s Role in Water Resource Management

Water availability and allocation are issues gaining a great deal of attention, particularly in arid climates. Increases in population growth and recent droughts bring urgency to measuring and monitoring water use in areas such as the western United States, where the majority of the water has already been allocated.

May 22, 2014Remembering Robert B. MacDonald

Earlier this year on Jan. 7, 2014, a giant in the world of Landsat applied science— Robert B. MacDonald—passed away. MacDonald was largely responsible for first envisioning and formulating how to use early Landsat data to estimate global crop production.

The U.S. Department of Agriculture’s (USDA) National Agricultural Statistics Service (NASS) updated its online geospatial exploring tool, CropScape, adding Cropland Data Layers from crop year 2013. This tool gives public an easy access to interactive visualization, geospatial queries and dissemination without the need to download specialized software.

Feb 4, 2014NASA Maps Earth’s Croplands from Space

It takes a lot of land to grow food for the world’s seven billion people. About a third of Earth’s terrestrial surface is used for agriculture. And about a third of that, in turn, is used to grow crops. Now, a new NASA-funded effort aims to map crop fields worldwide, identify what’s growing where, and determine whether it’s irrigated or fed by rain.

Sep 27, 2013Mapping the World with Landsat

Speeding around the Earth at 16,800 mph (27,000 kph), two Landsat satellites are quietly, expertly watching and recording changes in Earth’s lands from space. They are gathering data for people to make maps–all kinds of wonderful maps–of our cities growing, rivers flooding, lava flowing from volcanic eruptions, forests expanding or shrinking, crops greening through the growing season, and even of evidence of pollution.

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.

Jul 30, 2013Using 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.

Feb 19, 2013 • 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 role evapotranspiration plays in water availability. Why are evapotranspiration rates so important to know? It’s because the amount of water available […]

Jan 22, 2013What 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.
