UAS Mapping – Where Is It Heading?

The use of an unmanned aerial system (UAS) – cameras and Lidar sensors mounted on an unmanned aerial vehicle (UAV or ‘drone’) – to acquire geodata for mapping purposes has evolved beyond infancy and is now rapidly maturing. How will UAS mapping evolve in the foreseeable future? To envisage where exactly UAS technology is heading, it is appropriate to start with the big picture before examining the details. So what is the current big picture for unmanned aerial systems? How are they embedded in today’s society? First of all, our planet is confronted with climate change. The most threatening effects...

Land Challenges in a Revolving World

FIG Commission 7: Cadastre and Land Management
Has your world changed in the last four weeks? It has for Commission 7 also, and we are adjusting quickly to the new needs of our world. Commission 7 is about the relationship between land and people, and how surveyors and other professions support nations to administer their land resources. During this pandemic, every day the COVID19 virus is changing how we relate to our land from border closures to restrictions to citizens to be confined into private parcels. The current pandemic has shown how important it is to have a land inventory (the cadastre), and to be able to... (read more)

Accuracy Near, Far, Above or Under – How is FIG Working Week 2020 Contributing

The skills that engineering surveyors had to acquire in order to respond to the challenges of the construction world have made them capable, also, of fulfilling other challenges, several of which motivated by an awareness of the limitations of our planet. Engineering surveyors have learned that they need to push the equipment and techniques to its limits, while having recognized the necessity to integrate new techniques which can present more complete answers, without forgetting an important qualifier: accuracy. The instruments and methodologies have allowed for the surveying engineers to start working either very closely to the studied object, or, otherwise,... (read more)

Contribution of Hydrography towards Sustainable Water Management

FIG Commission 4: Hydrography
The 2019-2020 year has been a busy one with the Working Groups of Commission 4 focussing on representing FIG at a number of events and forum to gain insight to develops generally and also to deliver and present on the work of FIG. Through all its Working Group, Commission 4 has been actively involved in implementing its policy by working in close cooperation with relevant organisations and institutions. Altogether there are four (4) Working Groups for Commission 4 as listed below: WG 4.1 – Standards and Guidelines for Hydrography WG 4.2 – Blue Growth & UN Sustainable Development Goal 14...

Smart Surveyors: Developments and Trends from the FIG Working Week 2020

Some of the challenges demanding innovative surveying approaches and technologies are rapid urban growth, smart energy, cleaner mobility, and ‘land rights for all’. Sensing technologies, spatial data processing methods, and related approaches are already available. However, the question is how to use and improve them to become future proof, smart surveyors? Only ten years left to achieve the SDGs for a sustainable future. How can smart surveying contribute? To answer these questions, the papers of the FIG proceedings were analysed by the author-team.In this short article, we present the main trends distilled and the papers we refer to, represent these...

Spatial Information Management, a Key Discipline for Managing Spatial and Temporal Dynamics

FIG Commission 3
One of the most impressive examples of how phenomena evolve over time and space is the spread of the SARS-CoV-2 virus. Knowing in real-time where a local outbreak occurs, how outbreaks evolve over time, how many people are affected at any given location is of utmost importance to take appropriate measures. As with many other applications, well-established spatial information management, including an implemented system for digital information exchange can help to provide the required spatial information in near real time. Commission 3 at a glance Commission 3 of the International Federation of Surveyors FIG has the task of providing an... (read more)

FIG Working Week 2020 – Distance Matters…

What is the ‘FIG Working Week’? It’s a strange name for a conference, but a name that has become close to a trademark and is significant for the many varied activities that are going on during the – almost – week-long event. Since 1878, when FIG was established and gave surveyors the possibility to meet and network, the yearly FIG Conference has proven to be a unique meeting place for surveyors and geospatial experts around the world. But does it really matter to attend a conference, and to meet? Hanoi, Istanbul, Helsinki, Christchurch, Sofia, Kuala Lumpur, Accra, Rome, Marrakech, Sydney,... (read more)

State of the Art in 3D City Modelling

Six Challenges Facing 3D Data as a Platform
Semantically enriched 3D city models have the potential to be powerful hubs of integrated information for computer-based urban spatial analysis. This article presents the state of the art in 3D city modelling in the context of broader developments such as smart cities and digital twins, and outlines six challenges that must be overcome before 3D data as a platform becomes a reality. (This article is a co-production of seven authors, all of whom are mentioned at the end of the text.) 3D city models, as digital representations of urban areas, can be used to facilitate many applications, such as urban...

Towards a Digitized Citizen-oriented Armenian Cadastre

Armenia is moving towards a more transparent, secure, unified and citizen-oriented cadastral system. To achieve this, digitizing cadastral archives is essential. Digital availability of cadastral information will enable better management of lands, documented rights and tenure security for all Armenians. The Cadastre Committee has asked Kadaster, The Netherlands' Land Registry and Mapping Agency, for support. In Armenia there is currently no unified approach to archive cadastral and land registry records. The integrated cadastre on real estate has little ability to support management and assessment of lands and real estate, and the registration of the natural, economic and legal status of...

Bridging the Gap between Geospatial and Construction

There is certainly a gap in information exchange between the geospatial and construction domains. This is a serious issue, mainly because geospatial systems and engineering surveys are not yet aligned and integrated with building information modelling (BIM). The BIM method is expected to move construction activities from plan-based individual work to model-based collaboration. Such a paradigm shift will bring huge opportunities regarding planning, building and management of the built environment in a more productive, open and sustainable way. Although it is still difficult to entirely close the gap between these two fields, this article shows how that gap can at... (read more)
