Feature aware Digital Surface Model analysis and generalization based on the 3D Medial Axix Transform

Modern Digital Surface Models (DSMs) are highly detailed and cover large areas. This brings great advantages for applications such as flood modeling, crisis management and 3D city modeling. Unfor- tunately, and despite recent developments on this subject, current methods are unable to fully take ad- vantage of modern DSMs. First, because of...

Generation and generalization of safe depth-contours for hydrographc charts using a surface-based approach

Depth-contours are an essential part of any hydrographic chart|a map of a water-body intended for safe ship navigation. Traditionally these were manually drawn by skilled hydrographers from a limited set of surveyed depth measurements. Nowadays this process of map making is shifted towards the digital domain, not in the last place because of the...
