Water flow on, in and under glaciers still remains a poorly understood system. Water can flow over the surface of glaciers, as well as through channels inside and under the ice. The water thereby has strong influence both on ice melt and glacier dynamics, making glacial hydrology an important field of study.

Lidar point clouds provide excellent and quite accurate points in space, including the quite large rooms of factories or ships. Although they are much more accurate than point clouds derived by other means such as regular cameras or structure light systems, the problem remains that it is really difficult to correctly guess and reconstruct the surfaces from which these points have been sampled. It is typical to first guess and construct meshes from the point clouds, giving a potentially quite uneven structure where a flat wall or round pillar is supposed to be. Guessing whether such unevenness is true or an artifact of an inaccuracy is not impossible because there is a branch of computer vision called photogrammetry, which estimates surface curvature from color gradients. However, this still leaves the problem of cleanly terminating every surface by its edges, which may be sharp, rounded or ragged. Edge detection for sharp edges can be implemented by a well-known computer vision algorithm called the Hough Transform. By putting all these pieces together, a human can receive a lot of help in creating a CAD model from some images and a point cloud.
