为了在沿海地区进行大规模和昂贵的海洋工程项目的海上物流和维修，各机构必须在网上以易于理解和全面的方式向公众提供相关信息。然而，一个长期的挑战是时空（四维（4D））地理可视化算法的发展，该算法能够在互联网上基于地图的可视化中集成时变地理信息。在本文中，我们通过4D可视化概念解决了在基于web的应用程序中可视化海洋空间数据的挑战，重点关注可用性标准、性能参数、所需的实施工作，并提供支持多层决策的空间信息。我们使用Web Graphic Library （WebGL）通过原型实现来验证我们的概念。在我们的技术评估中，WebGL被证明非常适合开发交互式、响应式、高效和移动的基于web的地理信息应用程序，包括2D、3D和4D（时空）内容。在我们的研究中，我们确定了一些开放的研究问题，包括将图形变量映射到主题表现力，4D系统中时间维度的表示，通用时间概化，以及在基于web的地理可视化系统中整合（伪）逼真的插图。
For marine logistics and maintenance of extensive and expensive marine engineering projects in the coastal zone, it is essential that institutions provide the public with relevant information in an easily understandable yet comprehensive manner over the web. A perennial challenge, however, has been the development of spatio-temporal (four-dimensional (4D)) geo-visualization algorithms to enable the integration of time-varying geo-information in map-based visualizations on the Internet. In this paper, we address the challenge of visualizing marine spatial data in web-based applications through a 4D visualization concept, focusing on usability criteria, performance parameters, the required implementation effort, and delivering a breath of spatial information that supports decision-making on multiple levels. We used Web Graphic Library (WebGL) to validate our concept through a prototypical implementation. In our technology evaluation, WebGL proved highly suitable for the development of interactive, responsive, efficient, and mobile web-based Geographic Information applications, including 2D, 3D, and 4D (spatiotemporal) content. During our research, we identified a number of open research questions, including mapping graphic variables to thematic expressivity, representation of the time dimension in 4D systems, generic temporal generalization, and integration of (pseudo-)photorealistic illustrations in web-based geo-visualization systems.
