Technical Advances Bring Digital Twin of Underground Infrastructure Closer

Mapping the underground is one of the major challenges in creating an infrastructure map at the municipal, regional, and national level, which is a key foundation for a national digital twin. Recent technical developments include: the ability to collect data at highway speeds that can be used to create a 3D model of underground infrastructure, software that can extract relevant 3D underground information from consumer digital photography, and video capture. Meanwhile, novel ways to share information about underground infrastructure, and progress on standards for sharing information about the subsurface are making mapping the underground increasingly feasible. The uncertainty in the... (read more)

New Tasmanian Digital Elevation Model

A beta version Digital Elevation Model (DEM) has been constructed for Tasmania (Australia) by MRT geoscientists Dr Claire Kain and Colin Mazengarb, including the most recent Lidar imagery captured during the 2018-19 flying season. With nearly 60% of the state now covered by Lidar, the new dataset provides an increasingly clear view of the landscape that has many applications. The dataset was compiled initially to support two major projects being undertaken by MRT (Mineral Resources Tasmania) and other government agencies. However, as with the previous elevation model (created by the former Forestry Tasmania and shown as a hillshade image on the LIST website),... (read more)

GfK Releases Digital Maps for Asia

GfK has released a new, completely overhauled digital map edition for all of Asia. The edition features coverage of 49 countries, ranging from the three BRICS nations Russia, India and China to smaller countries such as Bhutan. In addition to more granular coastlines, the digital maps depict the latest status of administrative and postal regions. Detailed, up-to-date digital maps are a prerequisite for accurate location-based market analyses. GfK’s new Asia Edition 2017/2018 includes approximately 750 digital maps. These reflect the latest regional status and feature numerous new levels as well as a higher level of detail. GfK’s digital maps of... (read more)

New Challenges for Digital Chart Production

Advanced Technical Solutions Need to be Implemented
Hydrographic Offices (HOs) have realized that bathymetric data is not sufficiently represented in Electronic Navigational Charts (ENCs). A few aspects of this topic have already been touched upon in the presentation 'Innovative approach in automated contour generation' (Moggert-Kägeler, 2017) that was presented at Hydro 2017. This article focuses on the challenges of high-density bathymetry chart production and introduces a new approach to cope with it. In the past, ECDIS (Electronic Chart Display and Information System) users have repeatedly complained about the lack of bathymetric detail in ENCs. The resolution of depth information is too coarse to adequately display the extent... (read more)

Police, Thieves and a Digital Future

James Kavanagh, Land Group Director, reports on activities of, and relating to, RICS and gives some thoughts on thefts of surveying instruments. Winter is extending its icy grip across the UK but things are heating up on the surveying and geospatial policy and news fronts. I’m sure that many of you have been in attendance at one of the traditional evening lectures here at RICS HQ, it’s been quite and outstanding session so far with lectures on intelligent geospatial algorithms and automatic feature recognition for laser scanned points clouds (https://correvate.co.uk/), the amazing advances in satellite imagery and its applications and...

OSNI Digital Mapping Available Through viaEuropa

Europa Technologies has announced that Ordnance Survey Northern Ireland (OSNI) digital map data is now available to consume as a service through its award-winning viaEuropa platform. This development means that for the first time, OSNI data can be provided alongside mapping from Ordnance Survey (GB), thereby providing a complete mapping service for the United Kingdom. viaEuropa allows organisations to quickly and easily consume premium digital map content as a service, without incurring traditional data management overheads. The support for OSNI digital map data means that organisations with interests in Northern Ireland can quickly plug the service into their applications and... (read more)

Digital Asset Management with BIM App

3D Repo, a multi-award-winning provider of cloud software solutions for collaborative building information modelling (BIM), has started development on a mobile platform for Crossrail designed to manage maintainable assets. The cloud-based innovation by 3D Repo brings together previously disparate databases and information sources to provide on-site, instant access to both historical and real-time information. The project is funded under the Crossrail innovation programme, Innovate 18, which is designed to lead innovation in the construction industry.  Working with Crossrail, 3D Repo has demonstrated integration between information already held within asset lifecycle information management software. Through a Crossrail Asset Information and Configuration... (read more)

From Nautical Chart to Digital Marine Mapping

Digital marine mapping became possible with the arrival of the electronic chart. The authors, who pioneered the re-engineering of this data for use in GIS, question whether the requirement has been fully met or whether fundamental issues still exist. It has been over ten years since UK marine environmental and engineering consultancy, Metoc, started to re-engineer UK Hydrographic Office data to make it suitable for use in GIS. Mike Osborne and John Pepper, who pioneered this work and are now directors of marine data management and GIS specialist, OceanWise, consider how the requirement for digital marine mapping has changed over...

Seeing the Future: AI, BIM and Digital Twins

Digital Construction Week 2019
During Digital Construction Week (DCW), which was held at the Excel in London from 16-17 October 2019, there was one seminar stream on geospatial surveying and two specifically on building information modelling (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 buzzword was 'digital twin', which was heard in many talks and in the exhibition booths. The term digital twin is used quite flexibly, but essentially it implies that an object must have a digital representation which can be presented visually, i.e. a virtual... (read more)
