State of the Art in 3D City Modelling

Six Challenges Facing 3D Data as a Platform
Semantically enriched 3D city models have the potential to be powerful hubs of integrated information for computer-based urban spatial analysis. This article presents the state of the art in 3D city modelling in the context of broader developments such as smart cities and digital twins, and outlines six challenges that must be overcome before 3D data as a platform becomes a reality. (This article is a co-production of seven authors, all of whom are mentioned at the end of the text.) 3D city models, as digital representations of urban areas, can be used to facilitate many applications, such as urban...

5 Questions to Philippe Simard, President of SimActive

SimActive has recently added Lidar to its point cloud processing solution and launched a new training programme for unmanned aerial vehicle (UAV or 'drone') mapping. 'GIM International' touched base with Philippe Simard, president of the Canada-based company to find out more. Besides Lidar and UAV mapping, this Q&A also zooms in on artificial intelligence (AI) and machine learning and envisions the advances in photogrammetry we may expect in the coming years. We also took the opportunity to ask him how the coronavirus outbreak is affecting business. How is the coronavirus outbreak impacting your business? The entire SimActive team is working from...

New GNSS Receiver Module Opens Door for Ultra-precise Positioning for High-volume Applications

Septentrio has announced that it is starting high-volume production of mosaic TM-X5, the next-generation multi-constellation and multi-band receiver module. Featuring the latest GNSS technology, mosaic TM-X5 brings centimetre-level positioning to technologies such as robotics, automation, smart wearables and telematics, among others. Its small form factor and low-power design makes high-performance positioning accessible to volume applications. “For smooth, uninterrupted operation in the field, mosaic TM-X5 is the logical choice for an industrial-grade GNSS positioning module,” said Francois Freulon, head of product management at Septentrio. “In an industrial setting, the cost of equipment downtime can quickly get out of hand. We designed mosaic TM to be robust in difficult environments, ensuring continuous operation as well as quick set-up times for our customers.” Compatible with all GNSS constellations Septentrio’s mosaic TM-X5 was conceived to be one of the first GNSS receiver modules...

UAVs: Where to Focus on Next?

New Technologies Require New Knowledge and Regulations
In June 2018, RSPSoc's 'Photogrammetric Record' publication devoted 11 pages to determining which term they would use for drones. They ultimately decided on ‘unmanned aircraft system’ or ‘UAS’. However, the mere fact that this required 11 pages goes some way towards highlighting the complexity and cross-discipline potential that drones bring, not only to the remote sensing industry but also for multiple other uses, writes Peter Kinghan. Over the past decade we have seen a number of drone uses come through the tried-and-tested period, resulting in unmanned aerial vehicles (UAVs) becoming a proven technology for a range of industries and professions,...

Will Artificial Intelligence Die Another Silent Death?

Artificial intelligence (AI) was first presented as a potential solution for object recognition some 50 years ago, but died a silent death along its winding road, writes Mathias Lemmens in his latest column. Now, big geodata is driving the need for automated mapping and reviving the interest in AI. But will the optimistic promises of deep learning come true this time? Never before in history have humans generated such gigantic volumes of geodata as we do today. The production of images and point clouds using a wide variety of geodata acquisition technologies is just one side of the coin; on... (read more)

SimActive Launches New Drone Training Programme for Mapping

SimActive, the Canada-based developer of the Correlator3D photogrammetry software suite, announces a new training programme for drone mapping. The programme’s goal is to provide educational material and resources on how to effectively process drone imagery, to both neophytes and experts. The new offering includes educational documents, tutorial videos and monthly webinars as well as tailored training sessions, which can be provided both online or on-site. All aspects of data processing are covered, such as the generation of DSMs, DTMs, point clouds, orthomosaics and 3D models. “It is often difficult for drone mapping companies to differentiate themselves from competition and increase...

3D Target Launches New Version of Lidar Point Cloud Software

3D Target has announced the release of its SmartProcessing Lidar 1.2 software solution. SmartProcessing Lidar, fully developed by 3D Target, enables the production of high-quality georeferenced point clouds from the dataset surveyed with the popular Scanfly Lidar payload. Version 1.2.0.0 features various brand new tools and several improvements. Among other minor bug fixes, the version introduces a Lidar boresight calibration tool, quality reports generation, faster colourization of the point-clouds and Pix4D 4.5 export. “With the new features included in the SPL 1.2, our customers can calibrate their systems by themselves!”, said Paolo Girardi, 3D Target’s CEO. “To the RGB camera...

Using Lidar North of the Arctic Circle

Challenging Aerial Acquisition Mission in Greenland
The acquisition of precise geodata is a high priority in Greenland, the world’s biggest island and a place of great diversity. There, geodata is considered vital to support almost all aspects of community activities and also for the future development of the autonomous territory within the kingdom of Denmark. This article provides insight into an aerial acquisition mission made all the more challenging by Greenland’s unique Arctic location. In the summer of 2019, ASIAQ Greenland Survey commissioned the engineering company Niras to acquire Lidar data and photographic imagery of the five largest cities in Greenland: Nuuk, Sisimiut, Ilulissat, Qaqortoq and...

3D BIM Models for Heritage Asset Management

Moving beyond the Field of Data Capture for Digital Preservation
Research undertaken under a collaborative doctoral partnership between Historic England and the University of Reading, UK, is moving beyond the field of 3D data capture for digital preservation. It considers how critical information for the conservation, repair and maintenance of historic buildings can be visualized in 3D BIM models and how BIM processes can be used for the management of structured datasets that inform conservation and repair programmes. A pilot study has been conducted using the work of the UK Antarctic Heritage Trust and historic British research base ‘E’ on Stonington Island, Antarctica, to consider this potential. Building information modelling... (read more)
