NASA Monitoring System

NASA scientists have developed a regional visualisation and monitoring system for Central America and the southern Mexican states designed to make NASA Earth observations and predictions freely and readily accessible to anyone with an internet connection. The system’s Spanish acronym is SERVIR, which means 'to serve' and it features a Web-based data archive of maps and satellite imagery, decision-support tools and interactive visualisation capabilities. NASA devised the system in partnership with several other organisations, among them the US Agency for International Development, the World Bank and the Central American Commission for Environment and Development. Scientific and technical collaborators include the... (read more)

Drought Monitoring Using Gravity

The record-breaking drought in Texas, USA, that has fuelled wildfires, decimated crops and forced cattle sales has also reduced groundwater levels in much of the state to their lowest levels in more than 60 years, according to new national maps produced by NASA using data from the NASA/German Aerospace Center Gravity Recovery and Climate Experiment (Grace) mission. The map are distributed by the National Drought Mitigation Center at the University of Nebraska-Lincoln.     The latest groundwater map, released at the end of November 2011, shows large patches of maroon over eastern Texas, indicating severely depressed groundwater levels. The maps,... (read more)

Volcano Monitoring Improvements

Scientists from the USGS work with partners around the world to actively monitor the world’s volcanoes. They use seismometers to detect and monitor very small earthquakes that indicate that magma is rising. They also use GPS to detect changes in the size of the volcano. Volcanoes can be catastrophic. Lava flows and debris avalanches can choke major riverways, destroy bridges and devastate natural areas. The USGS has allocated over USD7 million in American Recovery and Reinvestment Act funds to 15 universities and state agencies nationwide to modernize the equipment in volcano monitoring networks and produce high-resolution maps of high-threat volcanoes....

Monitoring Russian Wildfire Rage

Wildfires in Yakutia, Russia, are being monitored by ScanEx specialists. Over the past week UniScan ground stations have received highly detailed optical images from the SPOT 5 satellite covering one and the same territory twice within an interval of several days. Multi-temporal satellite imagery enables to assess the changes in burnt areas, smoke direction and fire intensity. Data about the geography of possible fires is updated daily on the thematic SFMS service "Kosmosnimki - Fires" (see link below). According to mass media the area of natural fires almost doubled the 2010 figures. If in 2010 the fire blazes covered the... (read more)

Monitoring the Changing World

More than 200 researchers from over 24 countries congregated at the biennial POLinSAR workshop held at European Space Agency’s (ESA) centre for Earth observation in Italy. The workshop aimed to provide an opportunity to review the advances made in the technique of Synthetic Aperture Radar (SAR) polarimetry which facilitates monitoring geographical characteristics that may influence changes in the world and climate.   SAR allows polarised information to be measured in the signals backscattered from Earth to a satellite sensor. Polarimetric interferometry is achieved by using two polarimetric images, acquired from slightly different angles, to provide information on the 3D structure... (read more)

Monitoring Tsunami Disaster Areas

Space-based imagery is being used to assess disaster areas and direct relief efforts in areas hit by the tsunamis on 26th December 2004. Canada's RADARSAT-1 satellite previously acquired over 70 archived images of the affected regions and these are being used as baseline information to be compared with newly acquired imagery. Day and night, the satellite provides synoptic coverage up to 500km by 500km per image and collects information through clouds over areas currently experiencing monsoon conditions. This data is used to monitor and map flooding, and to locate areas of standing water creating potential breeding ground for mosquitoes carrying... (read more)

Monitoring Earth's Magnetic Heartbeat

With more than two years of measurements by ESA’s Swarm satellite trio, changes in the strength of Earth's magnetic field are being mapped in detail. Launched at the end of 2013, Swarm is measuring and untangling the different magnetic signals from Earth’s core, mantle, crust, oceans, ionosphere and magnetosphere – an undertaking that will take several years to complete. Read on to see an animation of new results from the constellation of Swarm satellites showing where the protective field is weakening and strengthening, and importantly how fast these changes are taking place. Although invisible, the magnetic field and electric currents in and around... (read more)

Mining Slope Monitoring Conference

3D Laser Mapping, UK, has published the programme of speakers for its forthcoming International Slope Monitoring Conference. Taking place on 25 and 26 July 2012 in Mokopane, South Africa, the programme is to include a keynote address from one of Anglo American’s principal surveyors, case study presentations by laser monitoring system SiteMonitor users, and a paper on slope failure by 3D Laser Mapping’s executive chairman and founder, Dr Graham Hunter. The conference will also provide hands-on training sessions and the opportunity for delegates to network with peers. Keynote speaker Huw Thomas, principal surveyor at Anglo American, has more than 20... (read more)

Mangrove Mapping and Monitoring

RS and GIS in Conservation and Management Planning
The mangroves of the Sunderban area in India are one of the most productive and diverse ecosystems in the world, and yet they are a threatened habitat. To formulate a conservation and management plan periodic mapping and monitoring of mangroves is a prime requisite. The authors demonstrate that remote sensing and GIS techniques, including visual interpretation, are effective and efficient techniques for this purpose. The objectives of this study are threefold: mangrove mapping and monitoring, database creation and conservation prioritisation. Essential parameters in monitoring mangrove areas are disturbance index and fragmentation level. The disturbance index provides a measure for the... (read more)

Sensor for Monitoring Applications

The Leica TM30 Sensor is designed for high-precision measurements and combines automatic, fast and silent operation to ensure that even the smallest movement in all monitoring applications is detected. The Leica TM30 integrates with Leica GeoMoS software to create a monitoring system.     The Leica TM30 succeeds the Leica TCA2003 and TCA1800 Total Stations and is designed specifically for use in monitoring applications. Equipped with direct drives based on piezo technology, the Leica TM30 accelerates extremely fast, allowing shorter measurements cycles when working with multiple prisms. The silent drives enable the TM30 to be installed in urban areas for... (read more)
