The book presents a collection of accepted papers from the 3DGeoinfo 2015 international conference held in Kuala Lumpur, Malaysia, from October 28 to 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 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 visualization, as well as 3D visualization on mobile devices
• 3D applications: city models, cadastre, LBS, etc.
