Urban Planning, Management and Decision-making in the Cloud
... and more
Page 12-15: Cartographer Kraak is a professor in Geovisual Analytics and Cartography at the University of Twente, ITC in The Netherlands, and is a long-standing and active member of the organisation he now heads up. Over the next four years, Kraak will shape the policy of the ICA, striving to make further progress on the steps taken by his predecessor Georg Gartner.
Page 16-19: While the three main types (ALS, TLS and MLS) of Lidar systems together serve a large number of applications, none of them are optimised for fast and flexible scanning in challenging locations, rugged terrain and complicated urban structures. Personal laser scanners (PLS) fill this void and are now evolving towards compact, agile and flexible solutions for mapping complex environments.
Page 21-23: How can the abundance of pixels be processed into photogrammetric products quickly and effectively? The answer lies in parallel computing. Today, computer clusters enable fast and affordable processing of photogrammetric tasks. Read on to learn how parallelism speeds up the creation of seamless orthomosaics.
Page 25-27: A country’s local spatial development can be derived from socio-economic indicators assigned to administrative units. Proper management and monitoring often require statistics at a more detailed level. However, it is difficult if not impossible to sub-aggregate the statistics to smaller areas than administrative units. A reliable alternative is to measure the intensity and extent of night-time illumination and the changes over time!
