Understanding the Drivers and Consequences of Global Urbanization using Emerging Remote Sensing Technologies
Is urban remote sensing really useful to local planners? Does the research community understand which applications, scales and data are most relevant and sought after? These and other questions were addressed in a recent workshop organized by the Geography Department at the Arizona State University.
Mapping Aquatic Vegetation on Lake Victoria
Invasive aquatic vegetation has been a serious issue in Lake Victoria over the past decade, hindering transportation as well as a profitable fishing industry. Remote sensing was used to map the spatial extent of aquatic vegetation on the surface of Lake Victoria as well as create time series animations to show growth and movement of the vegetation. Our results will be used by SERVIR and the Lake Victoria Fisheries Organization to conduct operational satellite-based surveillance and to protect local fisheries.
GEOSS in the Americas Leverages International Resources for Action
What can satellite-based Earth Observation do for the Americas? The possibilities are endless. From mitigating disaster outcomes in earthquake-prone states like Haiti to managing agriculture in Brazil to observing algal blooms off the coast of Mexico, GEOSS Americas is already having a major positive impact.
CBERS: a Chinese-Brazilian Collaboration
What do you do if you’re home to some of the world’s most significant natural resources, but you don’t have the technology to place satellites in orbit? In Brazil’s case, the answer is a long-lived collaboration with China called CBERS (China-Brazil Earth Resources Satellite), which started in 1988 and is still going strong. Today, Brazil has the ability to launch its own satellites, but the two nations continue their partnership.
The Land, Atmosphere Near-Real-Time Capability For EOS (LANCE)
Instruments aboard satellites make global measurements daily. But processing can take up to 40 hours. Agencies and others require these Earth Observing System products in near-real-time for everything from weather forecasting to national security. This article describes a NASA project called LANCE that processes data in three hours.
