Progress and New Trends in 3D Geoinformation Sciences

With the last ten years seeing breakthrough deployments of 3-D technology in geoinformation sciences, this collection of high-quality conference papers provides comprehensive coverage of new applications including 3-D cadastre, utilities and urban planning.

The integration of the 3rd dimension in the production of spatial representation is largely recognized as a valuable approach to comprehend our reality, that is 3D. During the last decade developments in 3D Geoinformation (GI) system have made substantial progress. We are about to have a more complete spatial model and understanding of our planet in different scales. Hence, various communities and cities offer 3D landscape and 3D city models as valuable source and instrument for sustainable management of rural and urban resources. Also municipal utilities, real estate companies benefit from recent developments related to 3D applications.
In order to present recent developments and to discuss future trends, academics and practitioners met at the 7th International Workshop on 3D Geoinformation. This book comprises a selection of evaluated, high quality papers that were presented at this workshop in May 2012. The topics focus explicitly on the last achievements (methods, algorithms, models, systems) with respect to 3D GeoInformation requirements.
The book is aimed at decision makers and experts as well at students interested in the 3D component of geographical information science including GI engineers, computer scientists, photogrammetrists, land surveyors, urban planners, and mapping specialists.

State-of-the-art contents Gives a comprehensive account of new applications based upon 3D Geoinformation Describes 3D cadastre, 3D utilities, 3D city and urban planning Includes supplementary material: sn.pub/extras
