Every month we will focus on a specific theme, featuring a selection of articles which have previously been published in GIM International magazine. By including a mix of older and more recent articles, we will present a complete recap of the subject. Furthermore, we will be bringing you a bi-weekly round-up of ‘Focus Stories’ related to the theme through our newsletter (sign up here). The theme for January 2016 is:
A point cloud is basically a large collection of points that are placed on a three-dimensional coordinate system. Point cloud files greatly speed the design process by providing real-world context where you can re-create the referenced objects or insert additional models. Point clouds are derived from raw data gathered by using a 3D scanner to obtain points from such things as buildings, topographies, or manufactured items.

Photogrammetry is the science of making measurements from photographs.The output of photogrammetry is typically a map, drawing, measurement, or a 3D model of some real-world object or scene.
Many of the maps we use today are created with photogrammetry and photographs taken from aircraft.
The A3 Edge digital mapping system is a sweeping camera system able to produce high-resolution and accurate imagery from high flight altitudes and hence to conduct surveys quickly...
Until now, most commercially available airborne Lidar systems have operated on one single wavelength, reflecting energy from a pulse which is then used for classification or visual...
3D reconstruction using dense image matching is a hot topic as it enables the automatic extraction of 3D urban models, notably from airborne oblique imagery. However, applying DIM...
The ancient imperial city of Fez, Morocco, is an important tourist attraction and has been listed as a UNESCO World Heritage Site since 1981. The layout of the city is complex, whi...
Currently, the extraction of objects from point clouds of urban sites is commonly done manually as automation is impeded by noise, clutter, occlusions and varying point density. Th...
Motivated by the increasing need of rapid characterisation of environments in 3D, the authors have designed a robot system that automates the work of an operator of terrestrial las...
