Virtual Geographic Environment Cognition is the attempt to understand human cognition of surface features, geographic processes, and behaviour, as well their relationships in real world. From perspective behaviour analysis simulation, previous work Environments (VGEs) has focused mostly on representing simulating world create an ‘interpretive’ virtual improve individual’s active cognition. In terms reactive cognition, building a user ‘evaluative’ environment complex experiment necessary yet...

Ecosystem balance is an important factor that affects healthy and sustainable urban development. The traditional cellular automata (CA) model considers only a few ecological factors, however, the MCR can account for factors. In previous studies, factors were added to CA model. Thus, minimal cumulative resistance (MCR) combined with Markov models simulation of expansion. To verify reliability method, Wuhan metropolitan area was selected as representative area, its expansion in past future...

As a fundamental component of trajectory processing and analysis, map-matching can be used for urban traffic management tourism route planning, among other applications. While there are many methods, high-sampling-frequency GPS data still depend on simple geometric matching which lead to mismatches when multiple points near one intersection. Therefore, this study proposed novel segmented method in were separated into intersection non-intersection points. Matching rules methods dedicated...

This paper introduces a scalable virtual learning environment of the Chinese University Hong Kong; an explicitly geographical, immersive, and sharable 3D space with comprehensive social elements. It is characterized by multi-user collaborative modeling, group approaches geo-collaboration, space-oriented hierarchical avatars, knowledge exchanging sharing based on geographic experiments. Applications for purpose public education experiment, indicated future works prove possibility to offer...

This paper presents a reality-virtual fusional campus environment. It is an online 3D platform with some aspects of real information merged together. The whole based on OpenSimulator detailed geo-models to represent the university campus. Some preliminary experiments were done integrate realistic virtual for making geo-environment not only indoor and outdoor models, but also representations physical world. overall motivation provide framework strong support reality-virtuality modeling in...

3D registration plays a pivotal role in augmented reality (AR) system. The existing methods are not suitable to be applied directly the mobile AR system for built environment, with reasons of poor real-time performance and robustness. This paper proposes an improved method which is based on SURFREAK KLT. increases building efficiency algorithm descriptors maintains robustness algorithms. To implement evaluate method, smart phone-based environment developed. experimental result shows that...

Most simulation-based noise maps are important for official assessment but lack local characteristics. The main reasons this of information that simulations only provide about expected levels, which is limited by the use large-scale monitoring sources, and updated infrequently. With emergence smart cities ubiquitous sensing, possible improvements enabled sensing technologies possibility to resolve problem. This study proposed an integrated methodology propel participatory from its current...

This article presents a method of noise measurement using reality–virtuality fusional avatar and the real-time visualization in an online virtual geographic environment (VGE). The links user with his/her world. Therefore, data collected by users real world can be simultaneously visualized A framework was proposed implemented based on OpenSimulator (OpenSim). mobile phones sensing application called ISEISense. Preliminary experiment carried out Chinese University Hong Kong campus. It is...

This paper presents a spatial data model used for modeling geospatial in virtual geographical environment. Most traditional approach information system abstracts physical world with entity and relationship between each other, put emphases on representing feature their topologies, whilst reality focus capacity of keeping vivid rendering, i.e. high fidelity. Taking into account both topological characteristic GIS spaghetti VR, We introduce here an integrated which could represent...

The Internet of Things (IoT) network is one the major sources Big Data generation for Twin Virtual Geographic Environments (TVGE) in which ubiquitous interconnected sensors have been widely applied to monitor urban environment, such as air pollution industrial parks. As number pollutants and density monitoring increase, amount data continues accumulate. Challenges arise quickly identifying abnormal clearly visualizing their features. There a necessity having novel tools techniques processing...

With the two cores of database and model-base, Virtual Geographic Environment (VGE) breaks limitations traditional Information System (GIS), which provides new support to study understanding our world. [...]
