Le week-end dernier, l\u2019IGN a de nouveau fait effectuer un survol \u00e0 infrarouge thermique au-dessus des Hautes Fagnes, en collaboration avec les services d\u2019urgence pr\u00e9sents sur place. Ces images permettent d’\u00e9valuer la chaleur du sous-sol et donnent ainsi une indication de la pr\u00e9sence de foyers d\u2019incendie souterrains. Un survol similaire avait \u00e9t\u00e9 effectu\u00e9 il y a deux semaines.<\/h5>\n

<\/p>\n

Les images thermiques offrent aux \u00e9quipes d\u2019intervention une vue d\u2019ensemble compl\u00e8te, actualis\u00e9e et pr\u00e9cise de la zone touch\u00e9e. Elles permettent d\u2019\u00e9valuer les r\u00e9sultats des interventions men\u00e9es ces derni\u00e8res semaines. Les risques de reprise des incendies sont ainsi localis\u00e9s et \u00e9valu\u00e9s avec pr\u00e9cision, ce qui permet de les \u00e9teindre plus rapidement et plus efficacement. Les services d\u2019intervention appr\u00e9cient particuli\u00e8rement de disposer de ces images. \u00c0 l\u2019heure actuelle, plus de 100 intervenants sont encore mobilis\u00e9s chaque jour pour lutter contre les incendies.<\/p>\n

Les zones de tourbi\u00e8res sont particuli\u00e8rement trompeuses en cas d\u2019incendies de v\u00e9g\u00e9tation. En effet, le feu peut couver profond\u00e9ment dans le sol et r\u00e9appara\u00eetre de mani\u00e8re inattendue \u00e0 la surface. Ce feu souterrain n\u2019est pas visible en surface, mais il peut \u00eatre d\u00e9tect\u00e9 \u00e0 l\u2019aide de ces cam\u00e9ras thermiques infrarouges.<\/p>\n

Dans le cadre de l\u2019incendie des Hautes Fagnes, l\u2019Institut g\u00e9ographique national r\u00e9alise des prises de vue a\u00e9riennes afin de soutenir les \u00e9quipes d\u2019intervention sur le terrain. Cette mission est men\u00e9e en \u00e9troite collaboration avec le NCCN (Centre national de crise) et le comit\u00e9 de coordination provincial de Li\u00e8ge.<\/p>\n

Des images peuvent \u00eatre obtenues rapidement gr\u00e2ce \u00e0 un contrat permettant une intervention rapide en cas de crise. Les prises de vue a\u00e9riennes sont r\u00e9alis\u00e9es par la soci\u00e9t\u00e9 Vansteelandt pour le compte de l\u2019IGN.<\/p>\n
