TLDR
The generative aspects of 4D data integration and the real-time monitoring of an integrated database are explained and the effectiveness of the system was verified by applying it to the large-scale infrastructure management of an elevated railway bridge and a sewer optical communication line.Abstract:
A 4-dimensional geographic information system (4D-GIS) for use as a spatial-temporal data mining platform is introduced. The 4D-GIS effectively integrates, manages, and analyzes spatial-temporal data, defined as 4D data (2D, 3D, and time change data). In this paper, techniques for integrating and analyzing spatial-temporal data are provided in detail. First, the structures of 4D data and the essence of data integration are explained. A change difference management method for historical data and the homotopical representation of complicated 3D configurations are proposed. Second, the generative aspects of 4D data integration and the real-time monitoring of an integrated database are explained. The effectiveness of the system was verified by applying it to the large-scale infrastructure management of an elevated railway bridge and a sewer optical communication line.read more

A framework for the representation of two versions of a 3D city model in 4D space
TL;DR: A conceptual framework with initial considerations for the implementation of a 4D representation of two states of a 3D city model and the data structure of such an approach, as well as the methodology according to which two existing3D city models can be compared, associated and stored with their correspondences in 4D.
Geographic information system (gis) to manage environmental noise in the city of medellin, co- lombia
TL;DR: The main goal of this environmental noise sources characterization is to find first, the acoustic noise prediction method that best agrees with local noise sources and second, to evaluate the need of acoustic corrections for the noise indicators analysed in the strategic noise maps.
