Projects (Selected)

20131121_145423 LiDAR Flight 1 IMG_0334
Uong Tuong Mine

Quang Ninh, Vietnam

A Unmanned Aerial Vehicle (UAV) or drone was successfully utilised to carry out a survey of 6.6km² of mine site and surrounds. Ground control and flying of the high resolution (30mm per pixel) aerial photography was carried out within one week and the Digital Surface Model (DSM) processed less than one week later. Deliverables from the UAV mapping included high resolution mosaiced imagery, point cloud data, DSM, digital terrain models (DTMs), contour maps, stockpile maps and a stockpile volume quantity report.

Reforestation Project

Kampong Thom, Cambodia

Our services included the procurement of the LiDAR system and aircraft for the mapping of 20km² of forest as a pilot for a ODA funded REDD project. GCI also operated GPS ground stations for the LiDAR calibration flights, LiDAR and aerial photography flights, as well as supervised the processing of the LiDAR and digital photos.

Nuclear Power 2

Ninh Than Province, Vietnam

GCI was selected by the mapping consultant to provide aerial photography, ground control and aerial mapping services for the Feasibility Study of Vietnam’s first atomic power station. Our services also included supply of 1:25000 topographic maps and existing aerial photography from Vietnam Government archives.
