Low-altitude (80-100 meters above ground level) digital images were obtained from a camera mounted on a 3DR Solo quadcopter, a small unmanned aerial system (UAS), in three locations along the Lake Ontario shoreline in New York during July 2017. These data were collected to document and monitor effects of high lake levels, including shoreline erosion, inundation, and property damage in the vicinities of Braddock Bay, Sodus Bay, and Chimney Bluffs State Park, New York. This data release includes images tagged with locations determined from the UAS GPS; tables with updated estimates of camera positions and attitudes based on the photogrammetric reconstruction; tables listing locations of the base stations, ground control...

Afin de garantir la continuité du réseau hydrographique sur les portions navigables, des axes hydrographiques ont été numérisés en 2006 par UNJLC correspondant aux tronçons exploités par la RVF ou la SNCC. Ces axes ont été numérisés à partir du réseau hydrographique transmis par SPIAF. In order to guarantee the hydrographic cover of the navigable portions, the hydrographic axes were enumerated in 2006 by UNJLC, corresponding exploited sections to RVF or SNCC. These axes were enumerated from hydrographic coverages transmitted by SPIAF.

Les données concernant l’hydrographie sont équivalentes d’une base à l’autre. Les données origine sont issues des fichiers transmis par SPIAF (Inventaire forestier). Pour les cours d’eau linéaire la base originelle était plus détaillée dans les fichiers SPIAF que les fichiers MONUC. C’est donc celle-ci qui a servi de référence. Par la suite la MONUC a transmis une base de meilleure qualité, contenant plus de cours d’eau et d’informations sur les toponymes et le type d’écoulement.Certain tronçons de rivières ont été digitalisé (mise à jour) sur image satellite par UNDP dans les provinces de Kinshasa, du Bas-Congo,du Katanga, Maniema, Nord et Sud-Kivu. The data concerning hydrography are equivalent from one database...
