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.
