UAS Mapping – Where Is It Heading?

The use of a UAS to acquire geodata for mapping purposes has evolved beyond infancy and is now rapidly maturing. How will it evolve in the foreseeable future? 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... (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)

Positioning the World for the Future

FIG Commission 5 focuses on meeting the highest level of accuracy for Positioning and Measurement. It provides the tools, techniques and procedures to educate and train surveying professionals everywhere. Appropriate methodology for data collection and processing are required to be successful in an era of global, integrated geospatial data. The body of work Commission 5 focuses on the science of measurement (instrumentation, methodology and guidelines). Its six WG’s focus on application of geodetic standards under ISO TC211 and TC176-SC6 to position within geometric and vertical reference frames using GNSS observations combined with multi-sensor systems to be as cost-effective as possible....

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...

Need for International Ethics Standards, Peace and Gender Equality

FIG Commission 1: Professional Standards and Practise
Commission 1 focuses on establishing a set of ethical principles that fits the surveying profession for reference by professional institutions. It also focuses on promoting greater understanding and improving community perceptions about the surveying profession, which is underlined by the foundation’s vision to improve gender equality and maintaining global peace and justice, in line with Goal No. 5 and 16 of the United Nations Sustainable Development Goals (UNSDG) respectively. Highlighting the sessions of FIG Commission 1 Commission 1 received a well coverage of technical papers for the topics related to Professional Practice, Boundaries and Women in Surveying. All the submissions... (read more)

SimActive Involved in Mapping a UNESCO Archaeological Site

SimActive, a leading developer of photogrammetry software, has announced that its Correlator3D product is being used to map the UNESCO World Heritage Site of Halin in Myanmar. The archaeological project has involved the deployment of drones to gather data necessary to prepare orthophoto maps and digital elevation models. The goal is to find new features as well as to assess the state of the known ones. These include monumental walls, dams and digging canals, many of which are still visible in the landscape. The resulting geospatial data can also be used to check that modern constructions or farming are not... (read more)

Practise Your Lidar Skills Online!

Capturing ‘just’ aerial photographs is often not enough anymore. Users require 3D models to fit in their new developments or to correctly assess the suitability of a terrain. For this, two options are available: ‘classic’ photogrammetry from aerial photographs or Lidar measurements. The advantage of Lidar is that the point cloud is a direct output from the sensor and can thus allow the capture of more detail. Often, Lidar is used together with aerial photography to add texture and colour to the collected height data. In this e-learning module, you will learn about the challenges and possibilities of Lidar data and its combination... (read more)

5 Questions to... Håkan Engman, Bentley Systems

What makes the digital city so relevant for geospatial surveyors, and what lies ahead for 3D city modelling? We asked these and a couple of other questions to Håkan Engman, the director of business development in the digital cities business unit at Bentley Systems. In that role, he is leading business management activities for OpenCities products. He is also responsible for the integration of the Swedish company Agency9 following Bentley’s acquisition of it in September 2018.  The ‘digital city’ or ‘smart city’ is a hot topic. What makes it so relevant for geospatial surveying professionals? In most cases, smart initiatives... (read more)
