ABSTRACT Videos embedded with spatial coordinates, especially when combined with additional expert insights, offer the potential to acquire fine-scale multi-time period contextualized data for a variety of different environments. However, while these geospatial multimedia (GSMM) data include abundant spatiotemporal, semantic and visual information, the means to fully leverage their potential using a suite of visual and interactive analysis techniques and tools has thus far been lacking. In this paper, we address this gap by first identifying the types of tasks required of GSMM data, and then presenting a solution platform. This GeoVisuals system utilizes a visual analysis approach built on semantic data points that can be integrated spatially, which in turn enables management in a unified database with combined spatio-temporal and text querying. A set of visualization functions are integrated in two investigation modes: geo-video analysis and geo-location analysis.

GeoVisuals：一种利用空间视频和相关地理叙事潜力的可视化分析方法

摘要 嵌入空间坐标的视频，特别是与额外的专家见解相结合时，提供了为各种不同环境获取精细尺度多时间段上下文数据的潜力。然而，虽然这些地理空间多媒体 (GSMM) 数据包含丰富的时空、语义和视觉信息，但迄今为止，缺乏使用一套视觉和交互式分析技术和工具来充分利用其潜力的方法。在本文中，我们首先确定 GSMM 数据所需的任务类型，然后提出解决方案平台，从而解决这一差距。该 GeoVisuals 系统利用建立在语义数据点上的可视化分析方法，可以在空间上进行集成，从而实现在统一数据库中进行管理，结合时空和文本查询。
