Bridging the Gap between Geospatial and Construction

There is certainly a gap in information exchange between the geospatial and construction domains. This is a serious issue, mainly because geospatial systems and engineering surveys are not yet aligned and integrated with building information modelling (BIM). The BIM method is expected to move construction activities from plan-based individual work to model-based collaboration. Such a paradigm shift will bring huge opportunities regarding planning, building and management of the built environment in a more productive, open and sustainable way. Although it is still difficult to entirely close the gap between these two fields, this article shows how that gap can at... (read more)

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,...

Aerial Photography Helps to Transform Policing in North Yorkshire

The latest aerial photography is helping the police in North Yorkshire, the UK's largest county, to save time and resources and transform policing. Supplied by Bluesky International and Getmapping under the Aerial Photography for Great Britain (APGB) contract with the Geospatial Commission, the high-resolution imagery is widely used across the force. Accessed via desktop GIS and mapping software, the up-to-date photography is benefiting operations and day-to-day services with applications including missing person searches, surveillance planning, anti-social behaviour management and crime investigations.  Complementing existing mapping resources, including Ordnance Survey MasterMap data and the recently introduced what3words geocoding system, the APGB imagery provides...

UAVs, an Important Tool in Nepal’s Land Sector

Nepal has recently made promising steps in the area of land policy and related legislation. The new Fit-For-Purpose Land Administration policies and government initiatives embrace new ways of data collection for land administration purposes.  According to the National Agrarian Reform Program every plot of land in Indonesia must be certified and registered by 2025. However, using the standard land registration methodology, this target will not be reached. Using Unmanned Aerial Vehicles (UAVs, or 'drones') is an emerging option. In the land administration domain, UAVs have already been piloted and demonstrated in a range of OECD (Organisation for Economic Co-operation and Development)... (read more)

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)

Simultaneous Capturing of Lidar and Imagery

How Major Cities May Benefit from a Hybrid Sensor System
People continue to migrate from rural areas to major cities, driving sustained urban growth and increasing the demand for accurate, detailed and up-to-date 3D city models. The creation of such models is still a cumbersome endeavour but new advancements, such as the combination of three sensor types – nadir camera, oblique cameras and a Lidar unit – in one and the same geodata acquisition system, may bring relief. Aerial surveys conducted in major cities in the UK and Ireland demonstrate the potential of this solution. Cities will continue to grow as long as the world’s population keeps flocking to urban...

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...
