UAS Photogrammetry and Railway Mapping

Pilot in Czech Republic Attains High-precision Results
Today’s photogrammetric software is able to create dense and precise digital surface models (DSMs), digital elevation models (DEMs) and orthoimages. But is the accuracy sufficient for highly demanding railway applications? A pilot project carried out in the Czech Republic demonstrates that unmanned aerial system (UAS) photogrammetry has great potential for collecting geodata meeting railway companies’ high standards of precision. Parallel computing based on 16 personal computers (PCs) was used to process the 11,000-plus images in a reasonable time span. Safeguarding the continuous operation of rail traffic entails maintenance of the rails, sleepers and gravel beds, design and construction of extension... (read more)

UAS-based Lidar: A Market Update

One of the most eye-catching developments in the surveying profession is the integration of unmanned aerial systems (UASs) and Lidar. Airborne laser mapping is no longer restricted to traditional aircraft only, but is now also available for unmanned aerial vehicles. UAS-based Lidar is particularly interesting for surveys carried out over relatively small areas. The quality of the captured data – i.e. point clouds – depends on the sensor performance and the flight-path accuracy. 'GIM International' has selected some examples of available solutions for UASs and Lidar. 3D Target 3D Target, an Italian manufacturer of measurement instruments, launched a new Scanfly product at...

UAS Captures Near-infra-red Mapping Data

DroneMetrex has announced that near-infra-red (NIR) mapping data has been captured with the TopoDrone-100. The radiometric quality has been achieved because DroneMetrex specialists performed the necessary camera modifications and have designed the external filters specifically to match the requirements for accurate, discriminative vegetation mapping. According to DroneMetrex, this is the first time in the UAV’s mapping history that NIR imagery has been captured at this level of quality. From the one flight sortie, TopoDrone-100 users are able to perform vegetation analysis mapping as well as 3D contours/DTM mapping. DroneMetrex offers their Extended Spectrum Mapping (ESM) camera modification as an option... (read more)

Schiebel UAS Supports Winter Paralympics in Sochi

The Schiebel camcopter S-100 UAS (in co-operation with JSC Gorizont Russia: Gorizont Air S-100) was in operation in Sochi during the XXII Winter Olympics and will continue to operate during the Paralympic Winter Games. From 7 March, the S-100 UAS will once again surveil the 50-kilometre area around the Olympic village. In and around Sochi, the S-100 is confirming its reputation as multi-purpose unmanned helicopter system which neither requires a take-off strip nor supporting launch or recovery equipment, and can be actively used both land and ship based. The system is designed for mobile and flexible implementation, which guarantees fast... (read more)

SenseFly Unveils UAS for Precision Agriculture

Swiss mini-drone manufacturer senseFly has announced the eBee Ag, a fully autonomous aerial imaging drone for precision agriculture applications. The UAV features a wide range of camera options and fully autonomous operation: flying, acquiring images, and landing itself. The eBee Ag enables growers and crop consultants to become much more precise in their work, said Jean-Christophe Zufferey, CEO of senseFly. The detail provided by its customised cameras and its software’s index calculations allows customers to analyse crop conditions remotely and in high detail. This means less time wasted on manual checks and less reliance on low-resolution satellite images or costly... (read more)

UAS Captures Aerial Video in Canterbury Cathedral

For the first time in the history of the famous Cathedral of Canterbury, England, permission was given to operate a remote flying camera inside and through the Cathedral. The EagleCam was manoeuvred to 400ft over the cathedral and inside hovering close to precious ceilings and stained glass windows to capture architectural detail and original viewpoints of the ancient monument. Eagle Video Productions combined the footage with a brief historical overview to create a video to encourage tourists to visit Canterbury Cathedral and the surrounding area. The company is trusted to video ancient monuments, schools, hotels and sporting events to provide... (read more)

Joint UAS Lidar Solution for Multiple Applications

In the exhibit hall at the recent International LiDAR Mapping Forum (ILMF) in Denver, Colorado, USA, Juniper Unmanned, Pulse Aerospace and YellowScan collaborated to showcase Lidar data acquisition capabilities from an unmanned aerial system (UAS). This collaboration highlights Juniper’s ability to engineer UAS solutions with hardware offerings from Pulse and YellowScan. As a result, the co-located exhibit booths were visited by interested conference attendees seeking to learn more about this technical solution. Acting as the solution developer, Juniper facilitated the integration of YellowScan’s Mapper sensor onboard the Pulse Vapor 35 UAS. The purpose of this partnership was to feature the... (read more)
