Les 5 et 6 mai, l\u2019Institut g\u00e9ographique national (IGN) accueille \u00e0 Bruxelles la premi\u00e8re \u00e9dition du Benelux Geodesists’ Meeting<\/em> (BGM). Pendant deux jours, les g\u00e9od\u00e9siens des institutions nationales de cartographie et de g\u00e9od\u00e9sie de Belgique, des Pays-Bas et du Luxembourg se r\u00e9unissent pour des \u00e9changes techniques.<\/h5>\n

Contexte<\/strong><\/p>\n

La g\u00e9od\u00e9sie dans ces trois pays se caract\u00e9rise par un haut niveau technique et une forte connexion avec les syst\u00e8mes de r\u00e9f\u00e9rence europ\u00e9ens et internationaux ETRS89, EVRS et ITRS. Les pays du Benelux partagent des d\u00e9fis similaires : la modernisation des cadres de r\u00e9f\u00e9rence nationaux, l\u2019int\u00e9gration du GNSS avec les syst\u00e8mes altim\u00e9triques et gravim\u00e9triques, l\u2019impact des mouvements du sol et de l\u2019\u00e9l\u00e9vation du niveau de la mer, ainsi que la demande croissante de services de positionnement fiables et de haute pr\u00e9cision.<\/p>\n

Bien que des contacts bilat\u00e9raux existaient d\u00e9j\u00e0, il manquait un forum sp\u00e9cifique pour des consultations techniques r\u00e9guli\u00e8res entre les g\u00e9od\u00e9siens du Benelux. La BGM vise \u00e0 combler ce besoin en offrant une plateforme informelle et technique pour l\u2019\u00e9change de connaissances, la coordination et l\u2019identification d\u2019initiatives communes. Le forum souhaite \u00e9galement contribuer \u00e0 une participation coh\u00e9rente du Benelux dans les instances europ\u00e9ennes et internationales telles que EUREF et UN\u2011GGIM.<\/p>\n

Institutions participantes<\/strong><\/p>\n

Participent \u00e0 cette premi\u00e8re \u00e9dition : des repr\u00e9sentants de l\u2019Administration du cadastre et de la topographie (ACT, Luxembourg), de l\u2019Institut g\u00e9ographique national (IGN, Belgique), de l\u2019Observatoire royal de Belgique, du Kadaster (Pays-Bas) et de Rijkswaterstaat (Pays-Bas).<\/p>\n

Programme<\/strong><\/p>\n

La premi\u00e8re journ\u00e9e \u00e9tait consacr\u00e9e au traitement GNSS, au monitoring et aux cadres de r\u00e9f\u00e9rence. Apr\u00e8s une session d\u2019ouverture avec des pr\u00e9sentations g\u00e9n\u00e9rales et une discussion sur les d\u00e9fis communs, ont suivi des sessions sur l\u2019analyse GNSS, notamment le lancement des calculs avec le logiciel scientifique Bernese au Luxembourg et l\u2019approche REPRO en Belgique et aux Pays-Bas, ainsi que sur le monitoring des services GNSS.<\/p>\n

La deuxi\u00e8me journ\u00e9e portait sur les syst\u00e8mes de r\u00e9f\u00e9rence, les syst\u00e8mes altim\u00e9triques et des sujets transversaux. La matin\u00e9e \u00e9tait d\u00e9di\u00e9e aux cadres de r\u00e9f\u00e9rence nationaux et aux transformations, suivie d\u2019une session sur les syst\u00e8mes altim\u00e9triques. Ceux-ci comprennent notamment les travaux belges pour le raccordement du syst\u00e8me altim\u00e9trique n\u00e9erlandais au r\u00e9seau scientifique fran\u00e7ais de nivellement, l\u2019int\u00e9gration de l\u2019information gravim\u00e9trique dans le nivellement belge, l\u2019approche n\u00e9erlandaise pour les mises \u00e0 jour r\u00e9guli\u00e8res du r\u00e9seau de nivellement et les projets luxembourgeois de modernisation. L\u2019apr\u00e8s\u2011midi \u00e9tait r\u00e9serv\u00e9e \u00e0 de courtes mises \u00e0 jour, un regard sur le contexte international et une session de cl\u00f4ture au cours de laquelle ont \u00e9t\u00e9 d\u00e9finies les actions de suivi et les d\u00e9tails de la prochaine r\u00e9union.<\/p>\n

Perspectives<\/strong><\/p>\n

La BGM vise une meilleure compr\u00e9hension mutuelle des activit\u00e9s et d\u00e9fis nationaux, des r\u00e9seaux professionnels renforc\u00e9s entre les g\u00e9od\u00e9siens des trois pays, et une contribution plus coh\u00e9rente du Benelux aux initiatives g\u00e9od\u00e9siques europ\u00e9ennes et mondiales. Sur la base de cette premi\u00e8re \u00e9dition, la fr\u00e9quence des futures rencontres et la rotation du pays h\u00f4te entre la Belgique, les Pays-Bas et le Luxembourg seront d\u00e9termin\u00e9es.<\/p>\n
