Orographic shading or black and white relief map (MDS) based on diffuse anisotropic lighting. Resolution 50 centimeters. Year 2017

Orographic shading or relief map, based on diffuse anisotropic lighting, created from the Digital Surface Model (MDS) of the 2017 LiDAR data. It has been made in grayscale and with a resolution of 50 centimeters. This approach uses terrain visualisation techniques that are alternative to traditional and based on diffuse rather than direct lighting. These methods enhance the relative elevation of each point against the classic analytical shading, showing the darkest concave surfaces and the brightest convex surfaces. Terrain lighting by combining direct and diffuse light sources improves object recognition in high resolution MDE.
