The July 2017 issue of GIM International zooms in on several topics within the broad geomatics spectrum. 3D city models are in the spotlight this month, with three articles focusing on this dynamic topic. Further, this edition contains two interviews (with FARO’s Bernd-Dietmar Becker and TU Delft’s Filip Biljecki) as well as a feature on oblique imagery. Last but not least, as big data is an inherent part of the geomatics industry today, Ian Holt has contributed a column on this much-discussed theme.
Bringing Reality into the Information Space (p. 14)
Growing Use of Oblique Imagery by Municipalities (p. 20)
Digital Image Matching for Easy 3D Modelling (p. 25)
Public Participation Using 3D City Models (p. 29)
The Tough Road from 2D Maps to 3D City Models (p. 32)
Surveying the World of Tomorrow (p. 35)
Page 29-31: The importance of involving the general public in the design of urban plans and development scenarios is widely recognised. Today’s web technology and availability of 3D city models at various levels of detail enable local governments to communicate spatial plans effectively to their citizens. They also enable citizens to comment on and propose alternatives, thus providing feedback to local authorities. The authors investigate the opportunities offered by e-participation in Kenya.
Page 14-17: GIM International’s Wim van Wegen recently met with Dr Bernd-Dietmar Becker, chief technology strategist and head of FARO Labs (the company’s research and innovation department) to discuss what we can expect from laser scanning and its role as key reality capturing technology in the years ahead.
Page 20-23: For municipalities, aerial imagery is a vital support for geospatial and thematic information extraction and planning processes. Until recently, only orthophotos produced by nadir aerial images were used for this, but the development of oblique-image cameras is opening up new possibilities.
Page 32-34: Since 2012 Dr Filip Biljecki has been investigating how to improve the level of detail (LoD) in 3D city models. For his efforts – which were published in a hefty book called Level of detail in 3D city models – he recently received a PhD degree from Delft University of Technology. In acknowledgement of the high standard of his research, he graduated with the rarely awarded cum laude distinction, providing GIM International with reason enough to interview him.
