GIM March-April 2018

This March-April issue includes details of mapping and surveying projects carried out with unmanned aerial vehicles (UAVs). Nowadays they are an indispensable part of the geospatial toolkit for many professionals, but in fact they have only gained a firm foothold in the geomatics industry over the past five to ten years. We hope that the articles in this edition of GIM International will give you new insights into how UAVs could be used in your survey activities.

In this issue:

Precise Positioning: The Future of UAV Mapping (p. 13)
UAV Technology to Survey High-speed Rail Corridor (p. 22)
Proving the Rescue Potential of Multi-sensor UAVs (p. 27)

 

UAS Photogrammetry for Mapping Mountains

UAS Photogrammetry for Mapping MountainsHigh mountains are attractive places for outdoor sports. However, sometimes they change from recreational areas into hazardous ones. All year round, falling rocks and landslides endanger hikers and mountaineers and may cause casualties. To avoid mountaineers setting foot on tracks that are prone to landslides or where they may get crushed by rockfalls, high-quality maps of recent data are needed. In this article, the authors show that unmanned airborne systems have great potential for rapidly mapping mountainous areas. 

UAV Lidar

Monitoring Coastal Erosion with UAV LidarUAV Lidar is being used in the French Mediterranean coast region to produce comprehensive topographic surveys with unprecedented productivity and level of detail, and several Lidar surveys are planned over the next two years. Read on for details of the context, technical setup and results of the very first survey

Selecting Drones for Mapping

Five Challenges When Selecting Drones for MappingUnmanned aerial vehicles (UAVs or ‘drones’) have emerged as a solution for many mapping and surveying projects. This article elaborates on five important challenges that should be considered when finding out which type of drone is the best fit. 

Taking Advantage of the Changing Marketplace of Geomatics

TRon Bisio, Trimblehe changing landscape of the mapping and surveying profession brings new challenges, even for a renowned manufacturer of geospatial instruments like Trimble. In view of the growing role of BIM, the rising demand for complete workflow solutions and the challenge of extracting meaningful information out of the immense volumes of point clouds derived from Lidar data acquisition, it is clear that geomatics is in transition. GIM International touched base with Ron Bisio, vice president of Trimble Geospatial, to discuss how his company is approaching the new geospatial reality.
