ABSTRACT

3D cartographic visualization of a continuous time-dependent phenomenon is not an easy task. The focus of this research is motivated by the struggle to visualize such a phenomenon. Based on the current state of the art, we implemented new visualization methods to visualize continuous time-dependent phenomena. All visualizations are based on the use case of road-traffic-generated noise in outdoor urban areas. These visualizations utilize the third dimension of the map scene. The first two methods focus on the variations of the noise in the vertical dimension (i.e. height). The third method is based on the idea of space–time cube and therefore utilizes the time variable as the third dimension. For demonstration purposes, all methods were implemented in an online application. Furthermore, user testing of those applications was conducted. This paper thus describes design, implementation and user evaluation of newly proposed methods for third dimension visualization.

摘要

连续时间相关现象的 3D 制图可视化并非易事。这项研究的重点是努力将这种现象形象化。基于当前的技术水平，我们实施了新的可视化方法来可视化连续的时间相关现象。所有可视化都基于室外城市地区道路交通产生的噪声的用例。这些可视化利用地图场景的第三维。前两种方法侧重于噪声在垂直维度（即高度）的变化。第三种方法基于时空立方体的思想，因此利用时间变量作为第三维。出于演示目的，所有方法均在在线应用程序中实现。此外，还对这些应用程序进行了用户测试。
