The book includes the contributions to the international conference “18th 3D GeoInfo”. The papers published in the book were selected through a double-blind review process. 3D GeoInfo has been the forum joining researchers, professionals, software developers, and data providers designing and developing innovative concepts, tools, and application related to 3D geo data processing, modeling, management, analytics, and simulation. A big focus is on topics related to data modeling for 3D city and landscape models as well as their many and diverse applications. This conference series is very successfully running since 2006 and has been hosted by countries in Europe, Asia, Africa, North America, and Australia. In the period 2006 to 2017, the proceedings has been published by Springer in this series with Thomas H. Kolbe being the editor of the 2010 edition of the conference proceedings. 18th 3DGeoInfo was organized by Technical University of Munich in cooperation with the German Society for Photogrammetry, Remote Sensing and Geoinformation (DGPF), the local associations Runder Tisch GIS e.V. (Round Table GIS) and Leonhard Obermeyer Center—TUM Center of Digital Methods for the Built Environment, and the City of Munich. The international program committee consisted of committee members of previous 3D GeoInfo conferences and further leading scientists in the field of 3D Geoinformation Science.

During the last decade developments in 3D Geoinformation 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 city models as valuable source and instrument for sustainable management of rural and urban resources. Also municipal utilities, real estate companies etc. benefit from recent developments related to 3D applications. To meet the challenges due to the newest changes academics and practitioners met at the 5th International Workshop on 3D Geoinformation in order to present recent developments and to discuss future trends. This book comprises a selection of evaluated, high quality papers that were presented at this workshop in November 2010. The topics focus explicitly on the last achievements (methods, algorithms, models, systems) with respect to 3D geo-information 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.

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.

The book presents a collection of accepted papers from the 3DGeoinfo 2015 international conference held in Kuala Lumpur, Malaysia from October 28 – 30, 2015. All papers underwent double-blind review by experts from around the globe. The conference brought together pioneering international researchers and practitioners to facilitate the dialogue on emerging topics in the field of 3D geo-information. The focus areas include: - Data Collection and Modeling: advanced approaches for 3D data collection, reconstruction and methods for representation- Data Management: topological, geometrical and network models for maintenance of 3D geoinformation- Data Analysis and Visualization: frameworks for representing 3D spatial relationships, 3D spatial analysis and algorithms for navigation, interpolation, advanced VR, AR and MR visualisation, as well as 3D visualization on mobile devices- 3D Applications: city models, Cadastre, LBS, etc.

This book is a collection of original research papers that focus on recent developments in Spatial Analysis and Modelling with direct relevance to settlements and infrastructure. Topics include new types of data (such as simulation data), applications of methods to support decision-making, and investigations of human-environment data in order to recognize significance for structures, functions and processes of attributes. Research incorporated ranges from theoretical through methodological to applied work. It is subdivided into four main parts: the first focusing on the research of settlements and infrastructure, the second studies aspects of Geographic Data Mining, the third presents contributions in the field of Spatial Modelling, System Dynamics and Geosimulation, and the fourth part is dedicated to Multi-Scale Representation and Analysis. The book is valuable to those with a scholarly interest in spatial sciences, urban and spatial planning, as well as anyone interested in spatial analysis and the planning of human settlements and infrastructure. Most of the selected papers were originally presented at the “International Land Use Symposium (ILUS 2015): Trends in Spatial Analysis and Modelling of Settlements and Infrastructure” November 11-13 2015, in Dresden, Germany.

Building information modelling (BIM) uses a combination of technologies and resources to capture, manage, analyse, and display a digital representation of the physical and functional characteristics of a facility. A Geographic Information System (GIS) offers tools for visualising and analysing built and natural environments and their impacts on infrastructure systems, such as land use, transportation, etc. This book offers a framework for how the geospatial and surveying industry can create and integrate BIM with GIS. Through practical implementation methods, readers will learn to merge GIS data with design and BIM data to enable digital twins. This book presents the following features: Integrates BIM and GIS from a geospatial and surveying point of view for the first time; Addresses the creation of BIM from existing constructed buildings instead of typical pre-construction scenarios; Explains how to deliver BIM-suitable surveys to surveyors and geospatial practitioners; Provides surveying and geospatial industry expertise in the collecting, locating, managing, and communicating of BIM; Introduces new knowledge on the validation and integration of BIM and GIS within the spatial industry. This is an excellent book for professionals working with 3D data for built-environment digital twins, such as city planners, land surveyors, and geospatial practitioners. It is also an insightful resource for those working and studying in the fields of GIS, surveying, and geospatial engineering, providing the most current tools and resources for dealing with BIM.

Nowadays 3D Geoinformation is needed for many planning and analysis tasks. For example, 3D city and infrastructure models are paving the way for complex environmental and noise analyzes. 3D geological sub-surface models are needed for reservoir exploration in the oil-, gas-, and geothermal industry. Thus 3D Geoinformation brings together researchers and practitioners from different fields such as the geo-sciences, civil engineering, 3D city modeling, 3D geological and geophysical modeling, and, last but not least, computer science. The diverse challenges of 3D Geoinformation Science concern new approaches and the development of standards for above- and under-ground 3D modeling, efficient 3D data management, visualization and analysis. Finally, the integration of different 3D approaches and data models is seen as one of the most important challenges to be solved.
