Development of 3D spatial profiles to support the full lifecycle of 3D objects

Can more accurate night-time remote sensing data simulate a more detailed population distribution?

Aging, shrinking cities, urban agglomerations and other new key terms continue to emerge when describing the large-scale population changes in various cities in mainland China. It is important to simulate the distribution of residential populations at a coarse scale to manage cities as a whole, and at a fine scale for policy making in...

Leveraging spatial model to improve indoor tracking

In this paper, we leverage spatial model to process indoor localization results and then improve the track consisting of measured locations. We elaborate different parts of spatial model such as geometry, topology and semantics, and then present how they contribute to the processing of indoor tracks. The initial results of our experiment reveal...

Spatial model-aided indoor tracking

In order to address the problem of indoor pedestrian tracking, this thesis reports a research on spatial models' ability to reduce tracking error of a WiFi positioning system. There are three main objectives in this research. First, it is to build a suitable spatial model for tracking. Second, it is to develop a tracking algorithm that can make...

Spatial models for architectural heritage in urban database context

Despite the GIS (Geographic Information Systems/Geospatial Information Systems) have been provided with several applications to manage the two-dimensional geometric information and arrange the topological relations among different spatial primitives, most of these systems have limited capabilities to manage the three-dimensional space. Other...

Residuals analysis for constructing 'more real' property value

The price of a real estate is based on its value. The real estate market, where the real estate price is established, is dynamic and undergoes continuous change. Considering the fact that nothing is fully deterministic or fully stochastic in nature, the author has put forward a compromise based on the conducted analyses in order to better...
