The passive sampling method allows the use of simple equipment to determine NO2 nitrogen dioxide and benzene concentrations at specific locations. Establishing a network with several measurement points is quick and requires little equipment. Passive samplers (cylindrical tubes of 3 to 7 cm long and 1 cm in diameter)are exposed to the open air for a fixed period, in about 3 meters high.By simple diffusion of the pollutant in the air, it is going to be trapped by the sampler. Usually the passive diffusion tubes are installed in narrow streets which are strongly influenced by traffic.

The BD-L-TC is a vector-based topographic database of Luxemburg at the scale 1:5000. The data is structured into 10 main themes, regrouping 60 different object-classes, partly with attributes. • Roads • Railroad/Energy • Buildings • Hydrography • Vegetation • Orography • Altimetry • Names • Administrative boundaries Extractions can be delivered based on a rectangle, a circle, a buffer, cropping according to the sheets 1:5000, 1:20000(TC) and administrative boundaries.

Diese Gebiete stellen die Brutreviere des Raubwürgers in Luxemburg dar. Die Daten wurden im Rahmen des Monitoringprogramms 'Raubwürger' der Centrale ornithologique und deren Feldornithologischen Arbeitsgruppe erhoben. Die Abgrenzungen der Reviere wurde dabei von den jeweiligen Kartierern vorgenommen. Diese Grenzen sind nicht starr und entsprechen nicht zwangsläufig der aktuellen Situation, da sich die Reviere entsprechend den Gegebenheiten verschieben können. Die Grunddatenerfassung dieser Brutreviere stammt aus dem Jahr 2006.

Ubiquitous access for citizens and companies to very high speed Internet is key for developing the national economy. Hence, the national strategy for very high-speed networks was elaborated in 2010 [http://www.gouvernement.lu/3938123/2010-strategie-ultrahaut-debit.pdf]. The general objective of the strategy is to position the Grand-Duchy of Luxembourg among the leading broadband countries and to enable citizens, companies and public players to reap the associated socio-economic benefits. The strategy is in line with Europe 2020, a strategy for smart, sustainable and inclusive growth, as well as the Digital Agenda for Europe (http://ec.europa.eu/digital-agenda). In the context of the Digital Agenda, the European Commission encourages broadband mapping exercises (http://www.broadbandmapping.eu/). The broadband mapping of municipalities indicates the percentage of households that can get fix access to very high-speed Internet, independent of the technology (copper cable, coax cable, optical fibre). The map is based on data provided on a voluntary basis by certain network providers and on estimations based on such data. Speeds are advertised speeds and may vary from actual speeds. <a href='https://download.data.public.lu/resources/carte-de-la-couverture-internet-ultra-haut-debit/20160811-152728/couverture_JUL_2016.xlsx'>Link to the data</a> <a href='https://download.data.public.lu/resources/carte-de-la-couverture-internet-ultra-haut-debit/20160811-151918/2016_6_uhd_1Gbit.pdf'>Link to the PDF map</a>
