All 3DIS platforms include GeoCue’s data-processing software suite True View EVO, which integrates with the Applanix POSPac. With its 120° fused field of view, the True View 635/640 provides 3D mapping with excellent vegetation penetration and wire detection in a payload package of 3.2–3.6 kg. True View EVO supports the direct creation of ground classified point clouds, surface models, contours, digital elevation models, volumetric analysis, wire extraction and similar products, without the need for additional third-party software.
GeoCue Group has released the True View 615 and True View 620 UAS lidar 3D imaging systems. The True View systems are compact, survey-grade 3D imaging sensors designed for small unmanned aerial systems.
True View 615 and 620 are equipped with Riegl’s miniVUX-2UAV laser scanner integrated with dual photogrammetric cameras. Position and orientation is provided by an Applanix APX-15 (True View 615) or extreme accuracy APX-20 (True View 620).
All True View 3D imaging systems are bundled with Applanix POSPac, True View EVO post-processing software and True View Reckon data management solution.
The Riegl laser scanner and dual photogrammetric cameras have been carefully configured to provide a fused lidar/imagery field of view of up to 120°. The system includes full post-processing software that generates a stunning ray-traced 3D colorized point cloud and geocoded images.
An upgrade path will be available to promote a True View 615 to a True View 620 by adding the Applanix APX-20 external inertial measurement unit.
The True View product line gives mappers and surveyors the ability to deliver high-quality analytic data with exact accuracies. These deliverables are generated using workflows and tools within GeoCue’s post-processing software, True View EVO. Examples of derived products include bare Earth models, profiles, cross sections, topographic contours, volumetric analysis and more.
“Our Quanergy-based True View 410 has rapidly become the standard for general purpose drone 3D Imaging, where moderate vegetation penetration and accuracies of 5 cm RMSE are adequate,” said GeoCue’s President, Lewis Graham. “The True View 615/620 provides a solution for situations where deeper vegetation penetration, wire extraction and extreme accuracy are required. These are great new additions to the True View product line.”
The True View 615/620 will be available for shipment late June.
The National Trust for Scotland commissioned Glasgow-based GeoGeo to carry out a drone survey of the inner Hebridean islands of Canna and Sanday in November 2018. Using an ultra-high-definition camera, the GeoGeo team not only pinned down the exact locations of archaeological features, but also revealed new archaeological sites.
Over five days,the drone navigated 400 kilometers to capture 4,000 images at a 3-centimeter resolution. After processing, the images created a minutely detailed 3D map capable of being used in a 3D printer to create scale models of the islands. With more than 420 million data points, it is currently the world’s largest complete island dataset captured by drone, claims GeoGeo founder Paul Georgie.

“We were blown away by the results and the possibilities of this technology,” said Derek Alexander, head of Archaeology at the Trust. “We’ve previously recorded archaeology on Canna and Sanday which proves that there were inhabitants as far back as the Neolithic, but this survey gives us information and detail we just haven’t had until now. We’ve been able to obtain exact plots of known sites, but also recorded the extensive traces of cultivation, such as rig and furrow field systems that range in age from the Bronze Age onwards.”

The cameras and software also will be able to help with seabird counts and habitat and coastal erosion monitoring, which are currently expensive and labor intensive, Alexander said. The trust will use the maps to update archaeological records and prepare for future groundwork and excavations.

GeoCue Group (via its wholly owned AirGon subsidiary) has completed the integration of the DJI Phantom 4 Pro RTK (P4R) into its AirGon Sensor Processing Suite (ASPSuite).
ASPSuite is a post-processing solution for GeoCue’s Loki direct geopositioning system for DJI and other manufacturer’s drones.
ASPSuite enables integration of the P4R with third-party L1/L2 GNSS base stations such as systems from Septentrio, Leica, Trimble, Topcon, CHC and others in a high accuracy post-process kinematic (PPK) workflow.
In addition to PPK processing, ASPSuite includes support for options often required in engineering-grade surveys such as:
vertical transforms (such as ellipsoid to country-specific geoids)
creation of and transformation between collection datums and local coordinate systems (site calibration)
application of antenna static and dynamic lever arm corrections
full support for Loki direct geopositioning systems.
The DJI D-RTK-2 base station (optionally available) for the P4R can only be used in RTK mode, and then only if it is being sited on a known location. The D-RTK-2 does not currently allow access to an observation file, preventing it from being stationed using an online positioning service such as OPUS, AUSPOS, Canadian Geodetic Survey services and so forth. An additional consideration in the integration into ASPSuite is that professional surveyors already have the survey kit that they need incorporated into this workflow.
GeoCue is offering camera calibration services for the P4R for customers who wish to do minimal or control-free high-accuracy mapping projects (the DJI “calibration” is an image de-warping algorithm, not a proper photogrammetric calibration). A test of a GeoCue-calibrated P4R using an OPUS-positioned base station and ASPSuite achieved about 4-cm horizontal and 5-cm vertical network accuracy (RMSE) with no ground control points.
