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.

3D is the New Normal in Switzerland

Switzerland is unique in that it is still the only country to have switched entirely to 3D for its national object-oriented topographic database. As users increasingly discover the advantages in terms of new workflows and services, nobody regrets leaving the 2D era behind. According to Swisstopo, the extra dimension creates no extra costs – only extra benefits. It took the Swiss Federal Office of Topography (Swisstopo) ten years to build an object-oriented topographic database in 3D, with the last objects having been completed in 2019. “Nothing is excluded now; everything you can think of is available in 3D. Even the... (read more)

Preparations for Inaugural Geo Connect Asia 2020 Gather Momentum

With just two months to go until the first-ever edition of Geo Connect Asia 2020, organizers Montgomery Asia have announced the first wave of speakers and exhibitors. This March, the inaugural event will be a focal point for the multi-billion-dollar ASEAN geospatial industry. The global geospatial market is predicted to be worth US$134 billion by 2025, with the Asia-Pacific region in particular expected to post the highest growth rates. This growth will be driven by the anticipated high demand for geospatial technologies as governments in the ASEAN region continue to invest in new infrastructure and other ‘smart’ initiatives, such as...

Downtown Dublin as a Lidar Point Cloud

A Highly Accurate, Diverse and Dense Annotated Laser Scanning Dataset of a City Centre
The advance of Lidar data acquisition technologies is substantially increasing the amount of spatial data obtained and it is becoming cost-prohibitive to process it manually. Artificial intelligence (AI) has now started to offer cost-effective solutions to analyse and utilize those big datasets. AI can be employed for scene understanding, accurately detecting objects and classifying 3D assets. These are the significant fundamentals of several applications including autonomous navigation, intelligent robotics, urban planning, emergency management and even forest monitoring. The most popular types of 3D spatial information for such applications are Lidar and imagery data. This article describes the dense annotated ground-truth... (read more)

SimActive Adds Lidar to Point Cloud Processing Solution

In response to the growing use of Lidar, photogrammetry software developer SimActive has integrated a new Lidar workflow in its Correlator3D product. The capability enables users to import a point cloud in the software and to perform registration with an image dataset. Using Lidar as control eliminates the need for traditional ground control points (GCPs) during image processing. Registration occurs during aerial triangulation, leading to a precise alignment of imagery with the Lidar data. Following this, Correlator3D can output colourized point clouds as well as seamless orthomosaics. “Removing the need to manually tag GCPs facilitates the integration of Lidar data... (read more)

Putting Drone Mapping into Practice in Malawi

Drone technology has improved to the point where take-offs are easier than ever. Flight planning apps such as Pix4Dcapture help aspiring pilots take to the skies. But what happens next? In 2017, the government of Malawi and UNICEF launched an air corridor to test the use of drones for humanitarian purposes – the first in Africa and one of the first globally with a focus on humanitarian and development use. In this context, UNICEF Malawi hosted Pix4D for a 3-day workshop in the capital city Lilongwe, aimed at local participants from a range of different sectors. The workshop’s objective was...

InSAR Satellite Technology Data Fills Niche for Forest Inventory

Remote sensing is a great way to learn more about our forests and manage them accordingly. Scion, a New Zealand government-owned research institute, is exploring new information-capture methods such as synthetic aperture radar (SAR). A recent study found that, while Lidar is still much more precise for predicting forest attributes, interferometric synthetic aperture radar (InSAR) has several other benefits to consider. Remote sensing involves recording data about an object, without making contact with the object. Interferometric SAR (InSAR) satellite technology is one method that has been used to perform forest inventory overseas, but a study that was conducted recently is... (read more)

How Drones Contribute to Mapping Iceland's Disappearing Glaciers

A new 3D process which involves old aerial photos and modern-day drone photography has shed light on accelerated ice loss from some of Iceland's largest glaciers. Dr Kieran Baxter from the UK's University of Dundee has created composite images that compare views from 1980s aerial surveys to modern-day photos captured with the help of state-of-the-art technology. This revolutionary technique has allowed Dr Baxter to document the dramatic ice loss on a group of outlet glaciers on the south side of Vatnajökull, one of the largest ice caps in Europe. Aerial mapping photographs taken by the National Land Survey of Iceland... (read more)
