GIM International: UAS Special 2016

Feature: Airborne Laser Scanning Using UASs

Page 10-13:Airborne laser scanning (ALS) offers a range ofopportunitiesfor mapping and change detection. However, due to the large costs typically associated with traditional ALS, multi-temporal laser surveys are still rarely studied and applied.Unmanned aerial systems (UASs)offer new ways to perform laser scanning surveys in a morecost-effective way, which opens doors to many new change-detection applications.

Feature: Modelling Prague Castle with UAS

Page 18-19:In a recent project to obtain detailed and accurateorthoimagesand3D modelsto support technical staff in maintaining Prague Castle in the Czech Republic, the site was captured by UASphotogrammetry. Videos and georeferenced panoramic images were also taken as a service to documentalists and to provide the basis for virtual tours for tourists!

Feature: Integrating UAS and Multibeam Echosounder Data

Page 23-26:Knowing the volume of material present in a gravel quarry can make the difference betweenprofit and loss. A gravel quarry in southwest Germany, is partially covered by artificial lakes. To确定卷of the above-water gravel dumping grounds and to map the bottoms of the lakes, high-precision data captured by anunmanned aerial system(UAS) was combined withmultibeam echosounderdata obtained by boat.
