GIM International: January-February 2020

GIM International January-February 2020

Since it is winter in the Northern Hemisphere, GIM International’s first issue of 2020 contains two articles involving lots of snow and ice. One of them takes you on a Lidar mapping journey across Greenland, and the other to Antarctica, where a British Antarctic Survey base has been digitally documented. Enjoy reading this issue! 

This edition contains the following stories:

- 3D BIM Models for Heritage Asset Management
- Using Lidar North of the Arctic Circle
- Simultaneous Capturing of Lidar and Imagery
- 3D City Model and Augmented Reality
- Analysing Mean Sea Level Variations across the Hormuz Strait
- Indoor Mobile Mapping Goes Mainstream

Simultaneous Capturing of Lidar and Imagery

Simultaneous Capturing of Lidar and ImageryPeople continue to migrate from rural areas to major cities, driving sustained urban growth and increasing the demand for accurate, detailed and up-to-date 3D city models. The creation of such models is still a cumbersome endeavour but new advancements, such as the combination of three sensor types – nadir camera, oblique cameras and a Lidar unit – in one and the same geodata acquisition system, may bring relief. Aerial surveys conducted in major cities in the UK and Ireland demonstrate the potential of this solution. Read on...

Lidar in the Arctic

Using Lidar North of the Arctic CircleThe acquisition of precise geodata is a high priority in Greenland, the world’s biggest island and a place of great diversity. There, geodata is considered vital to support almost all aspects of community activities and also for the future development of the autonomous territory within the kingdom of Denmark. This article provides insight into an aerial acquisition mission made all the more challenging by Greenland’s unique Arctic location. Read on...

3D City Model and AR

3D City Model and Augmented RealityThe city of Munich launched an innovation competition and provided developmental support to the winner, Holo-Light. This ultimately resulted in the development of an award-winning augmented reality-based 3D city model of the Bavarian capital in conjunction with GeodatenService München (Geodata Service Munich). This underlines the pioneering work of this German city in using state-of-the-art technology to visualize the future. Read on...

3D BIM Models for Heritage Asset Management

3D BIM Models for Heritage Asset ManagementResearch undertaken under a collaborative doctoral partnership between Historic England and the University of Reading, UK, is moving beyond the field of 3D data capture for digital preservation. It considers how critical information for the conservation, repair and maintenance of historic buildings can be visualized in 3D BIM models and how BIM processes can be used for the management of structured datasets that inform conservation and repair programmes. A pilot study has been conducted using the work of the UK Antarctic Heritage Trust and historic British research base ‘E’ on Stonington Island, Antarctica, to consider this potential. Read on...
