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.

Indoor Mobile Mapping Goes Mainstream

In his previous column about the future of indoor mobile mapping, Felix Reinshagen made the case for why this technology was on the brink of widespread adoption. That was just over a year ago, and a lot has changed since then: brisk expansion of the products and services on offer, together with a widening field of applications. So after another incredible year, Reinshagen has written a new column outlining why he believes that mobile mapping is well past the tipping point and is about to go mainstream. The emphasis now is on assessing data quality and establishing universal standards in... (read more)

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)

Night-time Mobile Mapping of Road Surface Luminance

Capturing Road Environment Lighting Inventories Using a Luminance-calibrated Mobile Mapping System
Lighting – which is measured in luminance plays a key role in improving road safety. A new measurement system is now being deveoped to evaluate night-time road lighting conditions based on luminance-calibrated 3D point cloud data. This new approach integrates imaging photometry, which is commonly used to measure road lighting, with mobile laser scanning techniques, which are mainly used to measure the 3D geometry of the road environment. There are many interesting potential applications of the resulting georeferenced luminance point cloud. In road traffic, the role of illumination is to improve the visibility of the road and the surrounding environment.... (read more)

Lidar Monitoring of Rock Glaciers with Improved Measurement Frequency

The 3D Geospatial Data Processing Group from Heidelberg University in Germany is conducting studies of rock glacier dynamics in a high-Alpine permafrost environment. The team is utilizing a RIEGL VZ-2000i terrestrial laser scanner and a UAV equipped with the RIEGL miniVUX-1UAV unmanned laser scanner. This fascinating research project is leading to new insights into rock glaciers. Short-interval (e.g. < monthly) topographic Lidar monitoring has begun to provide new understandings into a range of geomorphic processes. Such 4D data help us to better understand the dynamics of rock glaciers. Rock glaciers are creep phenomena of mountain permafrost. In the era of climate change, rock glaciers... (read more)

virtualcitySYSTEMS Wins OGC CityGML Challenge

The virtualcitySYSTEMS team was named the winner of the OGC CityGML Challenge at the OGC Toulouse Meeting in November 2019. CTO Claus Nagel joined the award ceremony in Toulouse and presented the prize-winning solution. The company expressed its thanks to OGC for developing the geospatial standards it uses as the foundation for its applications. (This news story contains a video) In late October 2019, the Open Geospatial Consortium (OGC) CityGML 3.0 Challenge, sponsored by Ordnance Survey, the Manchester City Council and the Triangulum EU project, was held in Manchester for the first time. The aim of the OGC CityGML Challenge... (read more)

Wingtra and PCI Geomatics Enter into Drone Maps Partnership

Wingtra and PCI Geomatics are teaming up to offer flexible software solutions, easier ground control for repeated surveys and one-to-one resolution – also known as DSM true ortho – image processing with the WingtraOne-Geomatica bundle. “In order to produce high-quality products, we generate digital surface models (DSMs) at one-to-one resolution,” said Kevin Jones, executive director of marketing at PCI Geomatics. “This means if you are producing one-centimetre imagery captured by the WingtraOne UAV, you can produce one-centimetre DSMs using Geomatica.” For more than 35 years, PCI Geomatics has been providing academics, governments and commercial enterprises with mapping solutions for aerial...

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...
