Need for Geospatial Data Grows Across the Country

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from the USDA’s rich science and research portfolio.

During the month of April we will take a closer look at USDA’s Groundbreaking Research for a Revitalized Rural America, highlighting ways USDA researchers are improving the lives of Americans in ways you might never imagine.

Over the past several decades, satellite imagery has emerged as one of the most valuable new tools in modern agriculture. At USDA’s National Agricultural Statistics Service (NASS), we strive to remain at the forefront of this technology to continually advance our statistical products in service to U.S. agriculture. To keep abreast of how our counterparts in other countries are implementing this exciting new technology, last month we hosted representatives from the Canadian and Mexican agriculture departments in a Tripartite meeting. As geographic neighbors and statistical collaborators, we are particularly interested in each others’ work and how we can learn from each other.

It was exciting to see that Statistics Canada, working with Agriculture and Agri-food Canada, is researching new remote sensing-based yield models, using vegetative indices, agro-climactic data, and survey data for 21 crops. As a result of this innovation, Stats Canada is planning to use only remote sensing to set their official estimates for these crops rather than conducting traditional surveys. This is a tremendous step forward for a statistical estimates program that we will be watching with great interest. Read more »

At the U.S. Forest Service, Climate Change is Going 3D

Understanding the effects of global climate change, especially the amount of precipitation contained in clouds, has been limited by the use of decades-old satellite technology. But now a soon-to-be launched NASA satellite, the GPM Core Observatory, will literally add another dimension to seeing into the complexity of clouds and the precipitation they may or may not contain.

“The new GPM satellite will give scientists much clearer and more concise data on rainfall estimates with more continuous areal coverage giving us a three-dimensional visual understanding of the effects climate change is having on the planet as far precipitation is concerned,” said Dave Cleaves, the Forest Service’s Climate Change Advisor.
