La couche routière est mise à jour grâce à des images satellites de moyenne résolution récemment acquises pour la période allant de 2005 à 2010. Les nouvelles routes forestières ont été digitalisées et organisées en fonction de la source de données (type d\u2019imagerie), de la date (date d\u2019acquisition de l\u2019image), ainsi que de l\u2019état de la route et son utilisation principale. Le statut des anciennes routes a été actualisé en fonction des observations plus récentes au moyen d\u2019images satellites. L\u2019affinage des données sur les routes publiques, départementales, régionales et nationales existant a été effectué sur la base des informations fournies par les cartes topographiques et le suivi terrestre pour les zones où la couverture nuageuse au-dessus des images rendait leur identification difficile. Etant données les différentes sources de cette couches, la précision des données est fonction de la résolution spatiale des images satellites utilisées. La dernière mise à jour était en 2013.", "geometryType": "esriGeometryPolyline", "sourceSpatialReference": { "wkid": 4034, "latestWkid": 4034 }, "copyrightText": "Ce jeu de données est produit le MINFOF et WRI avec le soutien de l'Agence Américaine\n pour le Développement International (USAID), du Ministère de \nl'Environnement de Norvège et le Département pour le Développement \nInternational de le Grande Bretagne (DFID) avec les contributions en \nlogiciel de ESRI et Erdas.
