FIG Working Week 2020: Take the Stage in Amsterdam!

Have you always dreamed about taking the stage? Geospatial surveyors now have a perfect opportunity to do so in the Dutch city of Amsterdam! Submit your abstract before 1 November for a chance to share your views, project results and latest research related to 'Smart Surveying for Land & Water Management' during the FIG Working Week 2020. The event will be held at the RAI Convention Centre in Amsterdam from 10-14 May 2020. Surveyors are playing an increasingly important role in land & water management, especially as our countries need protection from the effects of climate change: sea-level rise, floods, droughts...

Airbus and Sobloo Announce Finalists of Multi-Data Challenge within Copernicus Masters 2019

Airbus has unveiled the names of the three finalists for the 'Airbus - Sobloo Multi-Data Challenge' organised as part of the Copernicus Masters 2019. This international competition recognizes pioneering solutions, concepts and ideas for industry and society based on Earth observation data. Annually, different prize categories reward innovative candidates, in the fields of deep learning, big data analytics, smart mobility and industry 4.0. The 'Airbus - Sobloo Multi-Data Challenge' was especially looking for value-added solutions that use both Copernicus and Airbus Earth observation data. These services should also provide insight and have impact on areas like Natural Resources Consumption, Agriculture,... (read more)

The Role of Surveyors in the Evolution of BIM

Building information modelling (BIM) is becoming more commonplace within construction sectors globally, combining technology with improved collaboration to better manage projects and give them the best chance of complying with time and budget constraints. However, the BIM life cycle and efforts to espouse it are almost futile if surveying is taken out of the equation or, more realistically, brought in too late. It can be good to have a structure that is successfully using BIM to be delivered on time and within budget, but if it or any of its components are in the wrong position the consequences can be...

InSAR Used to Create Ground Stability Maps

Zooming on a Groundbreaking Revolution
Satellite radar interferometry (InSAR) is a technique that can measure millimetre-scale movement of the ground from space. It does this by comparing the return echoes, and thus the signal-path length, from two or more radar images taken over the same place, over time. Modern InSAR is now used by a range of industries concerned with ground or structural stability, from building development and control, to oil and gas production, to mining, to road and rail management. This article explains some key aspects of InSAR technology, including its innovative use to produce ground stability maps. Phase Shifters InSAR is based upon... (read more)

3D Modelling for Property Valuation in China

A High-resolution Remote Sensing-based Approach
Rapid urban development in China has transformed the cityscapes, with a dramatic increase in high-rise buildings. However, the current 2D property valuation methods neglect the vertical dimension, even though that aspect contains significant indicators that impact property value – such as types of views, scope of vision and daylight. 3D modelling of geographical data can help to change this in high-rise and highly-density areas, going beyond 2D to enable identification of complex property characteristics in the vertical dimension too. This article presents research to explore a 3D modelling approach using remote sensing data for more precise property valuation. The accelerating... (read more)

When Photogrammetry Meets Lidar: Towards the Airborne Hybrid Era

Combining Airborne Camera and Lidar Sensors to Take the Mapping Sector a Step Forwards
The airborne market for area-wide 3D data acquisition is experiencing a noticeable trend towards a hybrid mapping concept. In the near future, most airborne data collection will increasingly be performed by a combination of active and passive sensors. There are two main reasons for this. Firstly, collecting all relevant data while flying is an efficient and cost-effective solution, even when the flying restrictions and regulations are factored in. Secondly, exploiting the advantages of both light detection and ranging (Lidar) and dense image matching (DIM) point clouds will improve the quality of the final geospatial products. This article reports on the... (read more)

Against the ‘How to Lie with Data’ Classification

New Task-oriented Methods for Designing Choropleth Maps
Choropleth maps are widely used for presenting population density, social index or other normalized statistical values related to spatial units. One of the ‘white spots’ on the research and development ‘map’ of cartography is that conventional methods for creating choropleth maps are data driven and may lose extreme values or small clusters of extreme values (hot spots) due to an unfavourable setting of class breaks. In this article, the author presents a new method and evaluation measures which enable better preservation of important spatial characteristics. The methods and software implementation result from the aChor project. The choropleth map is a... (read more)
