LIDAR  ( Li ght  D etection and  R anging)   R ADAR : radio  waves are transmited   into  atmos phere , which spreads a part of the energy back to the radar’s receiver LIDAR :  transmits and receives electromagnetical radiation, but of a higher frequency   ( from  UV ,   VIZ   and   IR )   1. What is LIDAR? 1st  International Symposium of Technical Geography-Cluj Napoca 30-31th of May 2008
[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],2.  LIDAR APPLICATIONS  1 st   International Symposium of Technical Geography-Cluj Napoca 30-31th of May 2008
3. The principle of airborne LIDAR technique Echo signals resulting from different types of targets LIDAR  sensors, used for topographic applications operate in the near infrared band. Unlike photogrammetry,  LIDAR  data collection is not affected by sun angle and does not require collection to be performed in late fall or early spring for leaf-off conditions 1 st   International Symposium of Technical Geography-Cluj Napoca 30-31th of May 2008 Airborne Laser Scanner – RIEGL LMS Q560

LIDAR ( Li ght D etection and R anging) R ADAR : radio waves are transmited into atmos phere , which spreads a part of the energy back to the radar’s receiver LIDAR : transmits and receives electromagnetical radiation, but of a higher frequency ( from UV , VIZ and IR ) 1.

Editor's Notes

  1. « L’environnement est actuellement un sujet incontournable se situant au carrefour des intérêts du monde économique – politique - financier et social avec des implications majeures allant de l’échelle des intérêts individuelles jusque à l’échelle planétaire. La pollution environnementale et le changement climatique, avec leurs conséquences possibles dans le développement des phénomènes extrêmes (incendies, inondations, fonte des glaciers, vagues de chaleur, tempêtes,…) engendrent des déséquilibres économiques et sociales ayant des enjeux majeurs concernent tout individu, institution et nation » Dans ce contexte EnviroScopY SA ( ESYCH) est une nouvelle entreprise crée le 08.03.2006 ayant son savoir faire général dans le domaine des Sciences – Technologies - Management de l’Environnement , son métier dans le domaine de la Qualité de l’Air et sa vocation de créateur tant des Instruments High -Tech de monitoring des paramètres atmosphériques que des Modèles Complexes de Simulation comme aide à la décision des stratégies d’abattement. ESYCH s’adresse aux institutions impliquées de manière responsable dans l’assurance de la qualité de l’air ( et de l’environnement en général) qui ont besoin d’un support spécialisé (conseil), d’un partenaire de projet ou qui cherche de mesures et études avec des instruments et outils de modélisation complémentaires plus représentatives que celle actuelles. Les problématiques de l’ ozone en été et celle des poussières fines en hiver son pleinement visées. Les références de l’ ESYCH sont l’équipe des professionnels reconnus, l’ expérience et les publications attestant déjà l’utilisation avec succès des techniques et des outils proposées sur le terrain dans plusieurs projets effectués dans plusieurs pays. Au partenaire principal l’École Polytechnique de Lausanne (les laboratoires LPAS & EFLUM) s’ajoute un le CSEM (Centre Suisse d’Electronique et Microélectronique) , le parc scientifique de l’EPFL ( PSE ), et autres à l’étranger. Les opportunités de projets se situent tant en Suisse que à l’étranger dans le contexte du changement climatique et sa relation directe avec la pollution de l’air .
