Real-time Noise and Air Quality Monitoring

Sensaris is reporting the first trial for its environmental sensor series. Air pollution is one of the most important factors affecting the quality of life and the health of the increasingly urban population. Considered separately, air pollution policy is insufficient to reach climate targets and climate policy is not enough to reach air quality targets for example with respect to ozone, an air pollutant which will become more of a problem as the climate gets warmer.     Currently, the data of the different pollutants measured at the different stations in a city are typically aggregated to a single number,...

DEME Partners with Airobot for UAV Monitoring

DEME, a leading Belgian dredging, hydraulic engineering and environmental solutions group, provides solutions for global challenges such as overpopulation in coastal areas, increasing seaborne trade and the rising global demand for energy and strategic resources. The company is now teaming up with Airobot to use UAVs for digital terrain modelling. DEME is considering UAVs to improve the safety of their crews on the construction sites, said Lorentz Lievens, head of the survey department. To create digital terrain models, the land surveyors must work amongst continuously operating bulldozers, excavators and dumper trucks. On several sites it is not possible at all... (read more)

NASA-JAXA Partnership Improves Earth Monitoring

In a unique collaboration between national space agencies, the United States and Japan began combining elements of their satellite resources on Monday 12th April to increase a critical type of Earth observation data. The partnership will more than double the quantity of this data that is used to explore earthquake hazards, forest declines, and changing water resources in the Americas. This new partnership between NASA and the Japan Aerospace Exploration Agency, known as JAXA, uses NASA's Tracking and Data Relay Satellite System to download observations over North and South America taken by instruments on JAXA's Advanced Land Observing Satellite, or...

New Leica Software Integrates GNSS Monitoring Receiver

Leica Geosystems is pleased to announce the release of the new Leica GNSS Spider software version 4.3, the solution for GNSS RTK networks. The integration of the new Leica GM10 and many further enhancements respond to market demands and technology trends. With Leica Geosystems’ Customer Care Program, GNSS network providers profit from the product at no additional investment. Leica GNSS Spider software is a major component of an integrated suite of programs for GNSS networks, that also consists of Leica SpiderWeb for value added web services and Leica SpiderQC for quality control and data analysis. With its scalability and modularity,... (read more)

Monitoring Phenology of Low Floodplain Vegetation

Why would you monitor floodplains? This is a question you don’t have to ask a Dutchman. The Dutch have been living in their delta for centuries and are champions when it comes to flood water levels. Hydraulically rough vegetation types can lead to higher flood water levels during peak discharges, so that’s a good reason to monitor, but to measure the ecological value is another one. On Wednesday 13 July, Wimala van Iersel from the University of Utrecht presented the findings of her study, showing the performance of multi-temporal, high-resolution Unmanned Aerial Vehicles (UAV) imagery for analysing temporal height profiles...

Low-cost GPS Sensors for Deformation Monitoring

Monitoring Deformations on a Glacier with Wireless Sensor Networks
Deformation monitoring of glaciers is of great value to scientists with an interest in climate change. Due to the slow movements of glaciers, a semi-permanent deformation system is the best method to monitor the changes. Using low-cost GPS receivers that work in a wireless sensor network makes such a set-up feasible. Glaciers are large bodies of ice moving slowly downhill under the forces of gravity. On the way down, the ice deforms, creates crevasses, speeds up and slows down. The process involves huge forces. Monitoring these movements is of great scientific interest, but due to the slow dynamics a semi-permanent... (read more)

Reducing the Costs of Geodetic Monitoring

Developing an Automatic WLAN-based GPS Monitoring System
The full feature is online at http://member.gim-international.com/. Please subscribe for free using the Subscribe button in the left hand column. Monitoring is one of the main tasks in engineering geodesy. Apart from tachymeters, only GNSS receivers can measure 3-dimensional positions automatically and continuously. Geodetic dual-frequency receivers are expensive, generally costing over EUR20,000. In recent years, however, single-frequency receivers available for less than EUR100 each have proved capable of achieving almost the same accuracy as geodetic ones, thus representing a potential alternative for geodetic receivers. This article introduces the automatic GPS monitoring system which has been developed at the Institute of... (read more)

Funding for Slope Failure Monitoring Research Project

UK-based laser scanning specialist 3D Laser Mapping has embarked on a research project, in partnership with Durham University, following the award of a share of a multi-million pound government grant. The project aims to develop new models for slope failure monitoring, and will be used to improve the safety and operational efficiency of mining companies around the world. Knowledge Transfer  Partnerships (KTP) like this one between 3D Laser Mapping and Durham University help businesses improve their competitiveness and productivity  through better use of the knowledge, technology and skills that already  reside within UK colleges and universities. KTP supports  innovation-led partnerships... (read more)

IDS GeoRadar Introduces Remote Sensing Monitoring System

IDS GeoRadar, a leading provider of interferometric technology solutions and multi-frequency, multi-channel Ground Penetrating Radar (GPR) worldwide, has launched HYDRA-G, a radar-based technology solution specifically developed to support construction companies and geotechnical engineers in monitoring civil structures and cut-slopes. HYDRA-G is a compact, remote sensing monitoring system able to provide real time monitoring of sub-millimetric deformations in buildings, dams, tunnels, and cut-slopes, and trigger early-warning alerts in case of impending collapses to evacuate people and machinery at risk. C&H has been among the first companies to invest in the technology for civil structure and cut-slope monitoring. Since the very first phases... (read more)

Millimetre Accuracy Fundamental in Subsidence Monitoring

For a low-lying, densely populated country like The Netherlands, monitoring subsidence is critical. Until recently, tiny displacements in the ground could not be mapped nationally but the Sentinel-1 mission has now made this possible. Focusing on The Netherlands and Denmark, scientists have been using radar images from the Sentinel-1A satellite to pinpoint not only where the ground is stable, where it is rising and where it is sinking, but also – and importantly – by how much with millimetre accuracy. Images from November 2014 to April 2016 and 2.5 million measurement points were used to compile the displayed map, which shows subsidence... (read more)
