Geospatial Data in Support of 3D Cadastre

Zooming in on Recent Technical Developments

The urbanization trend is leading to an increasing number of people living in cities, thus also placing new demands on cadastral registration. To be able to register the complex infrastructures and built-up areas properly, the cadastre will need to consider the third spatial dimension. The 3D cadastre is based on 3D parcels (spatial units) which are single volumes (or multiple volumes) of space. Although the technology offers numerous possibilities for implementation of the 3D cadastre, there are still some open issues, as this article explains. We live in a three-dimensional world. Over the past decades, there have been an increasing... (read more)

Surveying Profession in Transition - FIG Congress 2018

James Kavanagh has given a report on the FIG Congress with particular reference to UK interests. Here we look at some of the wider issues from the technical sessions. Surveying is Transforming The congress provided an overview of the surveying sector as a whole, which is steadily transforming to meet future requirements. Although the precise circumstances vary from country to country, many of the presentations expressed the establishment of an open real-estate market as a common requirement in a globalised economy. Whereas the surveying market has been traditionally local and national by nature, and the professionals within the countries have... (read more)

NMCAs Pledge to Put Data Access at the Heart of EuroGeographics’ Activities

Facilitating access to geospatial information from official national sources is in the public interest and supports the public good say members of EuroGeographics. European National Mapping, Cadastral and Land Registration Authorities (NMCAs) recently agreed to put data accessibility at the heart of their association’s strategy. At its 2019 General Assembly – held from 6 to 9 October – hosted by Ordnance Survey Great Britain with support from Her Majesty’s Land Registry and Registers of Scotland, European National Mapping, Cadastral and Land Registration Authorities (NMCAs) agreed to make data accessibility a key priority. They also pledged to continue working in partnership... (read more)

EuroGeographics Enhances Open Data for 2017

Users of EuroGeographics pan-European open data will benefit from a series of enhancements to the latest release of EuroGlobalMap. 45 members of the Association for the European National Mapping, Cadastre and Land Registry Authorities have contributed to the 1:1 million scale dataset which includes an administrative theme providing boundary information. It also features a settlement theme with the addition of populated places and populated place ID for built-up area feature classes. Angela Baker, EuroGeographics, explained EuroGlobalMap is produced using official data supplied by their members which is harmonised to standard specifications. Following these latest updates, three themes are now generalised from our... (read more)

Geodesy and Land Administration - FIG Working Week 2017

GW was not at the Working Work in Helsinki in May, but FIG publishes most of the technical papers presented at the conference on its website www.fig.net. Richard Groom has been sifting through the proceedings and has drawn together papers on Geodesy and Land Administration and a few other interesting topics. The code in parenthesis indicates the session number where the papers were presented. It is some time since GW published an article by Chris Rizos on the Global Geodetic Observing System (GGOS). Kutterer (TS03C) provided an update. His paper gave a general overview of GGOS and its work in... (read more)

Automatically Creating 3D City Models with Tridicon Building Finder Modelling Solution

The automatic creation of GIS-ready 3D city models and textured buildings from aerial images or LiDAR is rapidly gaining importance across the industry as national mapping agencies and municipalities are seeking to convert their cadastre or base map from 2D to 3D to support better planning, taxation, civic engagement and the growing number of smart city applications. “For many years Leica Geosystems’ tridicon City Modeller has been Europe’s leading solution to automatically create textured 3D buildings from aerial data and existing building footprints with recognition accuracies greater 90%”, says Ruedi Wagner, vice president of geospatial solutions at Leica Geosystems. “Unfortunately,...

Bluesky Launches Online Renewable-energy Platform

A prototype version has been launched of a website which allows homeowners, solar installers and manufacturers, energy companies and government organisations to assess the suitability of individual properties for solar energy technology. The online system employs high-resolution geographic data, such as aerial photography and Lidar, as well as address records to accurately identify and assess a building’s suitability. This information is combined with details of actual energy tariffs, expected consumption, cost of installation and available subsidies to calculate the potential return on investment for solar renewable energy systems. The result of a three-year, EUR2.4 million EC-funded research project – the EAGLE... (read more)
