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)

Monitoring Rice from Space

Rice is the most important staple grain in the world. Ninety per cent of rice plantations are distributed across Asia, providing daily food for 2.5 billion people in this region. Rice plays an important role in the development of society and the civilisation of countries in Asia. Launching a satellite dedicated to rice monitoring is highly desirable for Asia and other countries of the world where rice is produced. RICESAT In 1999, when the Asian Association on Remote Sensing (AARS) celebrated the twentieth anniversary of the Asian Conference on Remote Sensing (ACRS) in Hong Kong, China, I proposed RICESAT.

Japanese Forest Monitoring

Volume Estimation and Forest Fire Detection with GIS
Forest fires, illegal logging, rehabilitation of degraded land and watershed management are worldwide problems, monitoring being aided by modern technology including earth observation from space, image processing software, GIS and general IT. The author provides an overview of Japanese initiatives in forest volume estimation and forest fire detection. This article is a translated and modified version of an article earlier published in the July 2004 issue of The Journal of Survey. The sustainable supply of natural, coniferous wood, important for local communities in Japan, requires information on structural forest parameters. However, the Japan Forestry Agency record agency contains such limited... (read more)

Fire Monitoring by Satellite

Testing of the operational ScanEx Fire Monitoring Service (SFMS) has been started. The service has been developed at the ScanEx Research and Development Center and unlike similar systems (e.g., NASA Rapid Fire, AFIS, etc.) it offers access to data of several satellites of low, middle and high resolution. For the purpose of the project daily satellite imagery of the Russian territory is carried out with the data received at UniScan ground complexes, deployed in Moscow, Irkutsk and Magadan. At the first stage of the service testing in July only data of the European part of Russia will be used (within... (read more)

Satellite-based Environmental Monitoring

A group of Saudi Arabian and European partners have completed a project to implement and provide satellite based environmental information products and services to the Presidency of Meteorology and Environment (PME) of the Kingdom of Saudi Arabia (KSA). The environmental monitoring covers all four environmental domains "land - air - coast - marine" and follows previous experience gained in the European GMES - "Global Monitoring for Environment and Security" programme. The providers are Summit Geoservices (KSA) and a European team lead by GAF and consisting of DLR, Germany and e-GEOS, Italy. The environment has become a synonym for quality of... (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)

Monitoring Vulcanoes with UAS

Testing the Suitability of Thermal Infrared Sensors
Insight into signs that prelude volcanic eruptions is key for protecting the lives, livestock and property of those living in the vicinity of a volcano. One key indicator is temperature rise. Using Mount Etna as a test site, the authors show that a UAS equipped with a thermal infrared sensor generates data similar to temperature data acquired by ground-based stations while avoiding safety risks for volcanologists.   Data from Earth observation satellites with high temporal resolution can be used to monitor volcanic eruptions on an intraday basis when combined with images from satellites with a high GSD but low repetition...

Monitoring Earthquake Fires in Japan

Real-time Fire-spread Prediction System
Earthquakes are often followed by outbreaks of fire. In Japan such events are frequent and cities are very vulnerable to fire damage. Optimal use of fire-fighting resources is crucial, including support systems for advance simulation of effects prior to and (in real time) during a disaster. The authors introduce a real-time, fire-spread prediction system. This article is a modified version of a paper published in the Japanese Journal of Survey, February 2004, pp. 30-32. During the 1847 Zenkoji, the 1923 Great Kanto and the 1995 Kobe earthquakes direct damage was made worse by the numbers of injured and houses further... (read more)
