Gexcel Presents Wearable Mobile Surveying System

Gexcel, an Italian provider of Lidar and imagery analysis software solutions, has entered the 3D mobile mapping market with its HERON system. HERON is Gexcel’s innovative professional indoor and outdoor real-time 3D surveying system, developed under an EC-JRC licence. Developed for challenging mapping and surveying tasks, such as deep dark underground mines or tunnels or in a complex industrial area, HERON is suited both for surveying, localisation and model-comparison tasks. Surveying For challenging surveying jobs the system works as follows. The surveyor wears the HERON backpack laser scanner and walks along the site without using GPS/GNSS, targets and trolleys. The...

Surveying the Past Using a Drone

Modelling the Caesar’s Camp Oppidum under Dense Cover

Archaeology has long been reliant on ground-level geophysical disciplines and aerial photographs shot from an aircraft or ultralight. Airborne observations not only enable remains that are invisible on the ground to be detected and studied in a non-destructive way, but also to pinpoint where reconnaissance probes or excavations should be performed. If a site is covered by dense vegetation, Lidar is the only tool practicable for aerial observation. Lidar was applied in a unmanned aerial system (UAS or ‘drone’) survey of the site known as ‘Caesar’s Camp’, situated in the French municipality of Changé/Saint-Piat, located 2km south of Maintenon. The... (read more)

Total Stations for Bavarian Surveying Agency

The Bavarian Agency for Surveying and Geographic Information (Landesamt für Vermessung und Geoinformation Bayern (LVG), Germany) will equip all of its Cadastral Offices with total-station technology from Leica Geosystems. Up to 500 Leica Viva TS15 total stations will be provided over a period of five years. The first batch of 154 TS15 total stations was delivered through this framework contract in December 2011. The LVG has 51 state survey offices with 22 satellite offices in Bavaria, which between them manage and continuously update the official land survey register containing over 10 million plots of land. 500 survey teams...

DJI’s Metric Camera for Aerial Surveying

DJI has released the X4S camera, a lightweight version of the large aerial cameras carried in manned aircraft. How do aerial or metric cameras differ to a DSLR? An aerial mapping camera is primarily designed to have a low distortion metric lens and reliable construction to maintain its calibration. To achieve this the cameras have very few moving parts, particularly those that would affect the lens focal length. Aerial camera lenses are very high quality and virtually distortion free. This, and a constant lens focal length, means that every pixel is in the right place. 3D mapping from photogrammetry is based on... (read more)

Surveying in the Valley of the Temples

Use of Full-waveform TLS in 3D Modelling of an Unstable Area

Full-waveform terrestrial laser scanning enables high-precision 3D topographic modelling of unstable rock valleys that is valuable for various geomorphological investigations. The area below the archaeological site of Temple of Juno in Agrigento, Sicily, is characterised by the presence of large sections of rock that have fallen down from the upper ridge. In this context, full-waveform laser scanning technology was tested for the production of a highly detailed 3D topographic model at two resolutions (2cm and 20cm) for simulating potential rockfall paths at the site. Along a long ridge outside the city of Agrigento, Sicily, is a UNESCO World Heritage Site,... (read more)

Foreign Surveying Control Tightened in China

China will increase the supervision of foreigners who conduct surveys and map areas of the country. Foreign organisations and individuals, who engage in surveying and mapping in scientific research and teaching programs, travel or exploration, must obtain approval from the government and accept supervision, the State Bureau of Survey and Mapping said. The number of foreigners conducting surveying and mapping in China is on the rise and many field projects have been carried out illegally, which have threatened the security of the country, according to the state bureau. The Chinese law on surveying and mapping states that foreigners must cooperate... (read more)

Continuous Surveying: the Future of the Sector

Surveyors have been working for centuries on creating cadastres, measuring buildings and other construction works, building roads and suchlike. Whenever there was a need for measuring with coordinates, the surveyor was called in. And, in effect, nothing has changed – and yet everything has changed too. After all, no one can claim that surveyors are working in the same way and at the same pace as they did decades ago. While it is true that the surveyors are called upon whenever measurements are needed, nowadays measurements are needed everywhere and on a continuous basis. Read on for thoughts on what...

Surveying a Complete Island in the Maldives

In December 2016, Aeromao – in collaboration with Foresight Surveyors – completed a full photogrammetric survey mission with an Aeromapper Talon over one of the most unique and exotic islands in the Maldives. In total, the mission surveyed an area of approximately 1 square kilometre at a ground sample distance (GSD) of 2cm/pixel. The unmanned aerial vehicle (UAV) flew at a cruise altitude of 100m AGL and collected 1,422 photos with an amazing level of detail. A digital surface model (DSM), orthophoto and point cloud were generated using Pix4DMapper. Despite the 2-hour flight-endurance capability of the Aeromapper Talon, the mission was... (read more)
