Service Description: A Hillshade is a greyscale 3D representation of the terrain, with the sun’s relative position (azimuth) taken into account for shading the image. Hillshades are a qualitative method for visualizing topography and do not provide absolute elevation values. This Hillshade was created using a Digital Surface Model from first return LiDAR data, instead of bare earth data, and was created using a multidirectional method, which combines light from multiple sources/directions. This method is advantageous because it displays more detail than a traditional hillshade. Provided in New Brunswick Stereographic Double Projection with CGVD2013 vertical datum. Produced in 2020, from LiDAR data acquired between 2015-2018. L’ombrage est une représentation tridimensionnelle en nuances de gris du terrain, la position relative du soleil (l’azimut) étant prise en compte pour l’ombrage de l’image. L’ombrage est une méthode qualitative de présentation de la topographie et ne fournit pas de valeurs d’élévation absolues. Cet ombrage a été créé à partir de données des premiers retours laser d’un modèle numérique de surface LIDAR, au lieu de données de surface nue, et d’une méthode multidirectionnelle qui combine la lumière provenant de plusieurs sources et directions. Cette méthode est avantageuse, car elle permet d’afficher plus de détails qu’un ombrage traditionnel. Fourni en projection stéréographique double du Nouveau-Brunswick avec la donnée du canevas altimétrique CGVD2013.
