Urban Metabolism is a conceptual framework for analyzing the flow of energy and materials within cities. This paper discusses evidence that satellite-observed nighttime lights can be used to map and monitor urban metabolism and review the observational requirements for designing an optimized satellite instrument.
Temporal Characteristics of Thermal Satellite Sensors for Urban Heat Island Analysis
How accurate are thermal satellite images compared to on-the-ground field measurements when it comes to assessing the urban heat island (UHI) effect in Hong Kong? This research suggests that thermal images can be useful on hot summer nights to evaluate the magnitude and distribution of Hong Kong’s UHI.
Very High Spatial Resolution Imagery for Urban Applications
A commercial satellite called WorldView-2 is the latest from DigitalGlobe. It includes new spectral bands to support vegetation and coastal analysis. This provides the potential for more robust modeling and discrimination of spectral signatures, resulting in more accurate feature extraction and land cover classification.
Satellite-Based Crisis Information and Risk Assessment: Contributions Following the Earthquake in W. Sumatra and the Mentawai Tsunami
When a disaster occurs, rapid mapping activities using satellite data can provide valuable information to support emergency response actions. Such was the case recently when severe earthquake and tsunami events hit Sumatra, prompting the contribution from the Center for Satellite Based Crisis Information, a service of the German Aerospace Center (DLR).
Imagery from the landslides in Brazil
– As the clouds cleared over Brazil, satellites were allowed a glimpse at the destruction caused by January’s landslides.
North Carolina Coastal Management: Satellite Monitoring of Coastal Wetland and Shoreline Changes in Pamlico and Albemarle Sounds, North Carolina
This article focuses on a NASA Applied Sciences National DEVELOP assistance to the North Carolina Division of Coastal Management (NCDCM) with the assessment of coastline changes and habitat loss in coastal wetlands utilizing satellite remote sensing. The Hyde, Tyrrell, and Dare counties in eastern North Carolina occupy the coastlines of the Albemarle and Pamlico Sound estuaries. The Pamlico Sound is the largest estuarine lagoon along the East coast of the United States.
NASA's Aqua and Terra satellites view Tropical Storms Blas and Celia
(NASA/Goddard Space Flight Center) Tropical cyclones Blas and Celia are both spinning in the Eastern Pacific Ocean, and two NASA satellites captured them in visible and infrared imagery.
Easy Access to Satellite Weather Data
Whatever the weather in Europe, EUMETSAT’s meteorological satellites will be observing it. The good news for researchers, climate modellers, and amateur meteorologists is that the data they produce are freely available for non-commercial or research purposes. You can even set up your own reception station.
