This mosaic was used to perform a land-use, land-use change and forestry (LULUCF) inventory in the framework of the Kyoto Protocol. Nearly 17 000 sample points were laid down on the SPOT mosaic with a stratified sampling design. The land use at each sample point was determined by visual interpretation of the corresponding SPOT image in 2006 and the Landsat - Thematic Mapper (TM) image from the Global Land Cover Facility (GLCF) in 1990. Statistics for the period 1990-2006 were computed and integrated in the first voluntary Kyoto inventory.

[Termes IGN] surveillance écologiqueRésumé : (Editeur) Over the last decades, Corporate Sustainable Development (CSD) has become one of the most important challenges for companies facing increasing pressure from regulators and their stakeholders. This new type of sustainability reporting is quite difficult to perform in a consistent and objective manner, as business activities are often large-scale (and even global) and stakeholders (sometimes with diverging interests) can have different views on the positive and negative impact of business activities. Pierre-Philippe Matthieu, who works for the European Space Agency (ESA), explains how earth observation satellites can help in this endeavor.

[Termes IGN] Zurich (Suisse)Index. décimale : 30.83 Applications océanographiques de géodésie spatiale Résumé : (Auteur) Despite the decrease in road traffic emissions air pollutant concentrations of nitrogen dioxide, particulates and ozone often exceed the limit values at urban sites in Switzerland. This project aimed at providing a dynamic and real-time assessment of ambient air quality and at improving the understanding of the interaction between road traffic emissions and urban air quality. It is designed as a feasibility study for dynamic air-pollution measurements in the local scale. Three research topics were being pursued in this thesis : air quality monitoring, satellite based positioning (GPS) of a measurement system in an urban environment and the influence of road traffic emissions on the air quality in the city of Zurich.
The data analysed are based on the autonomous operation of a measuring system on a tram in regular service. A dedicated measurement system was built to measure the concentrations of the three most relevant air pollutants in Zurich. These are nitrogen oxides (NO and NO2), aerosol particles (participate matter) and ozone (O3). Nitrogen oxides and ozone are measured using the standard techniques involving chemiluminescence of NO and UV absorption of O3, respectively. Particulates are measured using a diffusion charging particle sensor which suits the requirements for space, a short measurement period and resistance against vibrations. Furthermore meteorological parameters (temperature, humidity and pressure) were measured.
The tram was equipped with the measurement system. During two measurement campaigns in spring/summer 2005 and winter/spring 2005/06 the tram travelled on three different tram tracks, which cross the city in north-south or east-west direction. They represent the various characteristics of an urban environment, such as busy places and parts of the city without private road traffic. The measurements were being transferred in real-time using mobile communication technologies (GSM, GPRS). A web site was being updated in real-time with the position of the tram on a map, the measurements and the operating state of the measurement system and its sensors.
GPS was used for precise positioning and timing. Urban sites often degrade navigation accuracy and availability. Therefore, a suitable receiver was evaluated and techniques to provide precise and reliable positioning data were developed. The latter involves filtering and projective map-matching to exclude faulty positions and determine precise positions. Furthermore, standard position-time relations for the tram were determined to interpolate GPS outages, which last a few seconds up to a few dozens of seconds.
A dispersion modelling study was carried out for a 3-3 krn2 area in the inner city of Zurich using a state-of-the art numerical dispersion model. This involved the models NEMO (emissions from traffic), GRAMM (meteorology) and GRAL (dispersion) from the Institute of Internal Combustion Engines and Thermodynamics of the Graz University of Technology.
The feasibility of dynamic and real-time measurements and its limitations were shown by carrying out two measurement campaigns lasting 18 and 20 weeks in spring/summer 2005 and winter/spring 2005/06. The analysis of the measurements clearly show varying concentrations of air pollutants along the tram track as well as characteristic hot-spots at busy places.Note de contenu : 1 Introduction
