Drone-based LiDAR survey of oil and gas assets in the jungle of Gabon (80 000ha)

In difficult-to-reach places in Africa, LiDAR surveys are often prohibitively expensive and can take a long time to perform. Delays due to poor weather, long ferries and bureaucratic processes make it a challenge to undertake accurate and critical information regarding terrain conditions. Drone and LiDAR technology has evolved significantly in the past few years allowing high-resolution data to be made available over some of the … Continue reading Drone-based LiDAR survey of oil and gas assets in the jungle of Gabon (80 000ha)

Drone-based LiDAR surveys for the feasibility of renewable energy production

Drones have been used for many years post-construction of renewable energy projects such as solar and wind farms for inspection purposes. The use of a drone-based camera setup with either a thermal, multispectral or visible light spectrum sensor is an affordable, safe and fairly quick operation. But drones are becoming increasingly competitive in the pre-construction phases too. The feasibility studies are critical for renewable projects … Continue reading Drone-based LiDAR surveys for the feasibility of renewable energy production

Remote mine LiDAR surveys via the internet (drone-in-a-box)

3DroneMapping has been working hard to provide its clients, particularly in the mining sector, with a solution for rapid, high-frequency LiDAR surveys at remote sites. It was noticed particularly during COVID-19, that travel to and from difficult-to-reach sites for skilled personnel like surveyors and pilots became a challenge. As periodical surveys like stockpile report timelines are fixed, there became a great danger of delaying the … Continue reading Remote mine LiDAR surveys via the internet (drone-in-a-box)

Drone survey of a Mali lithium mine

3DroneMapping was appointed as consultants to undertake an aerial survey of a potential lithium mine site in southern Mali. The project comprised a total surface area of approximately 18 000 hectares. The client requested orthomosaics and DTM products be produced. Control points were placed around the site. These were surveyed to within 20mm accuracy with survey-grade GPS. As RTK was not an option due to … Continue reading Drone survey of a Mali lithium mine

Investigating the geometric accuracy of Propeller AeroPoints and Propeller cloud processing

Report compiled by Luke Wijnberg and Jonathan Swart from 3DroneMapping 14 June 2017 The Propeller AeroPoint is a smart ground control point (GCP) which aims to make the gathering of accurate data simple and affordable during drone surveys. These lightweight and durable units repeatedly record positional data during UAV flights, with each AeroPoint working collaboratively against each other; therefore the more AeroPoints used, the greater the accuracy … Continue reading Investigating the geometric accuracy of Propeller AeroPoints and Propeller cloud processing

3DroneMapping Emlid Reach PPK photogrammetry trials

3DroneMapping has been testing a PPK system for the past year to integrate into our daily workflow. The point of PPK (or Post Processing Kinematic) is not just to improve internal photogrammetric model orientations but also is general recognised as a way of undertaking full-scale surveys at the same accuracy but without having to place time-consuming ground control points. 3DroneMapping set up a calibration site … Continue reading 3DroneMapping Emlid Reach PPK photogrammetry trials

Drone Mapping in Gorongosa National Park Mozambique

Gorongosa National Park is a 4000 square kilometer nature reserve in central Mozambique. In the 1950s it boasted some of the greatest animal densities in Africa, with over 500 bird species, abundant carnivore populations, as well as reptiles. The park originally began as a hunting reserve in the 1920’s and became a popular destination very quickly. A camp was built in 1940 for administration and … Continue reading Drone Mapping in Gorongosa National Park Mozambique

Drone Mapping in Zanzibar

3DroneMapping was approached to assist in a topographic and bathymetric survey of 2000ha in Northern Zanzibar. This semi-autonomous island lies off the coast of Tanzania in East Africa. The land has been provisioned for the development of various resorts, marina, airfield and golf course and is the biggest Zanzibar has seen with many investors and shareholders throughout the world. Site identification and Control The cadastral … Continue reading Drone Mapping in Zanzibar
