Surveying Profession in Transition

Report on FIG Congress 2018
The beautiful city of Istanbul in Turkey played host to the XXVI International Federation of Surveyors (FIG) Congress from 6-11 May 2018. With the theme of ‘Embracing Our Smart World Where the Continents Connect: Enhancing the Geospatial Maturity of Societies’, the congress brought together more than 2,300 professionals, academics and specialists from over 90 countries to discuss the current and future challenges of surveying. More than 400 papers were presented in a hundred sessions, including joint sessions with partners such as UN-GGIM, UN-Habitat, FAO and World Bank. This article looks back on some of the key highlights of the event. The welcome... (read more)

Co-seismic Displacement Estimation

Improving Tsunami Early Warning Systems
Geomatics is not primarily aimed at investigating the causes and physical phenomena related to earthquake events. It has, however, over recent years established a fundamental role in monitoring and describing changes to the Earth’s surface. In particular, this article describes the state of the art of the GPS contribution to Seismology, and presents an innovative methodology, VADASE, that enables accurate estimation of co-seismic displacement waveforms in real time using standard broadcast products and high-rate carrier-phase observations collected by a unique GPS receiver. This represents a potential enhancement to GPS Seismology and an effective support for tsunami early warning systems. The... (read more)

Managing Massive Point Cloud Data: Performance of DBMS and File-based Solutions

Today, Lidar and photogrammetry enable the collection of massive point clouds. Faced with hundreds of billions or even trillions of points, the traditional solutions for handling point clouds usually underperform. To obtain insight into the features affecting performance, tests have been carried out on various systems and the pros and cons have been identified. (By Oscar Martinez-Rubi, Peter van Oosterom and Theo Tijssen, The Netherlands) Point clouds have traditionally been processed into grids, vector objects or other types of data to support further processing in a GIS environment. Today, point clouds are also directly used for estimating volumes of complex objects,... (read more)

Future Trends in Geospatial Information Management

UN Expert Committee Regards Connectivity as Key to Growth
The most significant changes in the geospatial industry in the next decade will come not through a single technology, but rather from linking multiple technologies together. Especially the development of big data analytics will boost smart use of the location component to integrate data from many sources. The United Nations Committee of Experts on Global Geospatial Information Management (UN-GGIM) sees precise location information forming a core part of tomorrow’s all-connecting IT infrastructure. Read on for its insights into the trends over the next five to ten years. (By Frédérique Coumans, contributing editor, GIM International) In December 2015 the United Nations published... (read more)

Flood Identification from Radar Imagery

Mapping Flooded Urban and Rural Areas in Slovenia
Time series of satellite radar images are very useful for monitoring the extent and dynamics of floods and the devastations caused. A time series of four medium resolution radar images (ENVISAT, RADARSAT-2) captured after heavy rainfalls scourged Slovenia early autumn 2010, revealed overestimations and underestimations of the extent of flooded area in and around Ljubljana, the capital of Slovenia. The authors examined the sources underlying the deficiencies to gain insight into the possibilities of radar imagery for mapping flooded areas covered with a great diversity of land use types.   Between 17th and 19th September 2010, Slovenia endured enormous rainfalls...

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. Building information modelling... (read more)

Bringing Geography into Everything

GIM International Interviews Ed Parsons
As Google’s geospatial technologist, Ed Parsons is responsible for evangelising Google’s mission to organise the world’s information using geography. GIM International caught up with this ‘man with a mission’ in Barcelona during one of his countless foreign trips. (By Wim van Wegen, GIM International) You’re the geospatial technologist at Google, responsible for evangelising Google’s mission to organise the world’s information using geography. Can you describe that mission? In many ways it’s quite a unique role since the number of people within Google that are really focused on outside the organisation is quite limited. A key aspect of the role is... (read more)

Recent Advances in Geodata Acquisition Technologies

No Information without Data
Today’s geodata acquisition technologies combine microprocessors, computer power, solid state drives, complementary metal-oxide-semiconductor (CMOS) sensors, miniaturisation and many more developments. But demand is just as important as supply, and demand is rapidly increasing in our changing world. Read on for details of recent advances in geodata acquisition technologies. In today's world, we are seeing metropolises cluster to form megalopolises, climate change threatens humans, land and livestock in low-lying areas such as river deltas and valleys, and massively populated areas are prone to earthquakes and landslides. All of these factors are increasing the demand for geodata acquisition. This article starts with total stations, continues... (read more)

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...

Intergeo 2017: Transition from Providing Solutions to Value Partnership

Intergeo 2017, the world’s leading fair and conference on geodesy, geoinformation and land management, recently took place in Berlin and provided an open global environment for the geoinformation community and geomatics technology sector to see the current state of the art and look into the future. In addition to Intergeo’s role as marketplace for the geomatics industry itself, it helps the global sector to position itself in the changing world economy set in a digitalised world. Characteristics of Intergeo 2017 Compared to the last three Intergeo events, Intergeo 2017 was the first to attract more than 18,000 visitors from 107... (read more)
