Geomatics World Spring 2020

Geomatics World Spring 2020 cover

This Geomatics World Spring issue of 2020 shows what the future might hold. Three of the articles in this magazine focus on artificial intelligence and the potential benefits of a digital transformation for businesses, which could be passed on to users. In his column, Gordon Johnston, Chair of the RICS Geomatics Professional Group, welcomes you to a new decade for the geospatial industry.

A selection from the articles as published in this edition:

- Automated 3D Point Cloud Data Processing Using AI
- Seeing the Future: AI, BIM and Digital Twins
- Downtown Dublin as a Lidar Point Cloud
- The Art of BIM Implementation

Downtown Dublin as a Lidar Point Cloud

Downtown Dublin as a Lidar Point CloudThe 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 Lidar dataset that was generated in 2019. The labelled dataset was produced from Lidar data of Dublin that was captured alongside aerial images of Dublin in 2015. Both datasets are publicly available and their URLs are included in this article. Read on...

BIM Implementation

The Art of BIM ImplementationBuilding Information Modelling (BIM) is a means of creating a data-rich digital representation of an asset, be that buildings or infrastructure. The processes behind BIM form the foundations for smart information production (digitisation) and management through the lifecycle of the project. BIM encourages all project parties to work collaboratively, aiding project efficiency, de-risking project cost models and programmes, and enabling use of the model to inform operations and maintenance decision-making in the future.

AI, BIM and Digital Twins

Digital Construction Week 2019Digital Construction Week was held at the Excel in London on 16-17 October 2019. DCW covers all aspects of construction with a large exhibition, seminar and conference sessions. There was one seminar stream on geospatial surveying and two specifically on BIM, but relevant topics such as artificial intelligence (AI) and visualization, as well as BIM, cropped up in many of the other sessions. The most used buzz word was digital twin which was heard in many talks and in the exhibition booths. Read on...

Automated 3D Point Cloud Data Processing Using AI

Digitising Reality: Automated 3D Point Cloud Data Processing Using AIInstruments for digitising the 3D real environment are becoming smaller, more lightweight, lower-cost and more robust and so are finding widespread usage, not only on surveying tripods for the highest accuracy, but also on mobile platforms such as autonomous vehicles, drones, helicopters, aircraft, robotic vacuum cleaners, trains, mobile phones, satellites and Martian rovers. Lidar uses laser scanning, while photogrammetry records images from one or more cameras which may be moving. Each laser scan records tens of millions of data point position and colour in a point cloud and hundreds of such point clouds may be combined. This article discusses the challenges, such as management, storage, registration, fusion, extraction of useful and actionable information that many companies and organisations face after obtaining vast 3D point cloud datasets.
