GRIFINOR: Integrated Object-Oriented Solution for Navigating Real-Time 3D Virtual Environments

This paper introduces a generic method for representing geospatial features in an object oriented paradigm, and further applies this method for the representation of interactive and dynamic objects in 3D city models. The idea of the proposed method is to represent every geospatial feature as a managed object, which refers to an object-oriented and platformindependent binary representation that carries both the executable behaviors and attribute data regarding a feature. Aiming to be used for large-scale representation and implementation of geospatial data, a conceptual pattern is proposed to structure an interoperable while freely customizable depiction of the spatiotemporal properties, visual properties, thematic properties, and behaviors of geospatial features. A framework that enables the suggested method in a 3D platform is also elaborated. This framework defines the most essential components that support the associations between managed objects and the platform for fulfilling dynamic and interactive visualization tasks. The presented method is implemented in an energy project as a solution for representing energy features that support numerical calculation, dynamic visualization and user interaction.

“…It provided fully integrated and adaptable solutions that can be used for different purposes, ranging from urban planning to civil protection. Another example is the GRIFINOR platform (Bodum, Kjems, Kolar, Ilsøe, & Overby, 2005). It enabled navigation in a 3D virtual environment with different functions for emergency management, utilised distributed computing facilities in a real-time geo-visualisation system, and combined these applications with a series of analytical tools.…”

A collaborative virtual environment (CVE) is a shared virtual environment used for collaboration of many participants that may be spread over large distances. CVEs have been widely used in emergency management, especially for education, training and assessment. This paper describes the design and implementation of a prototype system that facilitates emergency management via a CVE using real-time spatial information. In particular, a method for automatic integration, modeling and visual simulation using real-time data from multiple online sources is proposed. Moreover, strategies are presented for using CVE-based scenarios for carrying out training, and testing preparedness measures. A novel technique has also been developed for real-time situation monitoring. Based on a system development (SD) research approach, the performance and functionality of the system was tested and evaluated. The use of real-time data acquisition and simulation was deemed to improve the processes of emergency management by increasing engagement, enhancing training and supporting decision-making of first responders and emergency managers.

“…The society is facing an important paradigm change of spatial information; from 2D to 3D [1][2][3][4][5][6]. This can be directly seen in the societies' growing interest for 3D geographic tools such as Google Earth, Virtual Earth, Second Life, GRIFINOR [7] etc. and also in the trend of development of all the large GIS manufactures.…”

Abstract. The development and maintenance of the infrastructure, facilities, logistics and other assets of the Port of Rotterdam requires a broad spectrum of heterogeneous information. This information concerns features, which are spatially distributed above ground, underground, in the air and in the water. The data are managed in a variety of data models with varying levels of dimensionality, granularity, accuracy and upto-dateness. Additionally increasing number of 3D design models is becoming available. This complexity of tasks and diversity of information challenges the Port authority to look for more advanced 3D solutions. This paper presents research in progress related to developing a 3D SII in support of information and process management within the Port of Rotterdam.
