Following the idea that a public good should also serve the public, it is our goal to make volunteered geographic data and derived analysis results accessible for a wide audience. Since data descriptions need to be particularly self-explaining as well as expressive for a wide applicability, textual description and visualizations will complement each other. Text provides self-contained explanations while visualization adds information-rich representations that can be perceived and processed quickly by users. However, geographic data is often complex especially if it has both a spatial as well as a temporal component. Resulting challenges for analysis and presentation of the data are, for instance, to identify the right subset of information and results, to integrate various levels of data abstraction, and to make the underlying algorithmic data analysis transparent and trustable. Previous research on geographic data, including various visual analytics systems, mostly focused on professional and expert users. In contrast, the goal of the proposed project is to research understandable and self-explaining representations of spatiotemporal geographic information. We plan to investigate fundamental methods to represent the data as well as research questions related to application and user acceptance. Expert-authored sample reports will form a basis to study how humans abstract, describe, and, illustrate complex spatiotemporal patterns for accessible reporting. Combining natural language generation and geographic visualization techniques, we will automatically create reports following these examples. Interactive refinement will allow users to personalize the reports according to their preferences and to explore the data from their perspective. Different types of spatiotemporal data – for instance, geo-referenced documents, movement trajectories, or networks – require the development of new summarization and reporting techniques. Based on these techniques, our approach is applicable to various application areas including city life, transportation, environmental scenarios, and emergency situations. We plan to build example systems for several of these application areas together with experts from the respective fields. Evaluating these demonstrators in user studies will provide insights what are the criteria for acceptance of such data-rich interactive reports by users from the general public and decision makers.

遵循公共产品也应该为公众服务的理念，我们的目标是让广大受众能够获得自愿提供的地理数据和派生的分析结果。由于数据描述需要特别具有自我说明性和广泛适用性的表现力，文本描述和可视化将相辅相成。文本提供了独立的解释，而可视化则增加了信息丰富的表示，用户可以快速感知和处理这些表示。然而，地理数据通常是复杂的，特别是当它既有空间成分又有时间成分的时候。因此，对数据的分析和提出的挑战是，例如，确定正确的信息和结果子集，整合不同级别的数据抽象，以及使基础算法数据分析透明和可信。以前对地理数据的研究，包括各种视觉分析系统，大多集中在专业用户和专家用户。相比之下，拟议项目的目标是研究时空地理信息的可理解和自我解释的表示法。我们计划调查表示数据的基本方法，以及与应用程序和用户接受度相关的研究问题。专家撰写的样本报告将形成一个基础，以研究人类如何抽象、描述和说明复杂的时空模式，以便进行可访问的报告。结合自然语言生成和地理可视化技术，我们将根据这些示例自动创建报告。交互式改进将允许用户根据他们的喜好个性化报告，并从他们的角度探索数据。不同类型的时空数据--例如地理参照文件、移动轨迹或网络--需要开发新的摘要和报告技术。基于这些技术，我们的方法适用于包括城市生活、交通、环境场景和紧急情况在内的各种应用领域。我们计划与各自领域的专家一起为这些应用领域中的几个领域建立示例系统。在用户研究中评估这些示范者将提供洞察，普通公众和决策者接受这种数据丰富的交互式报告的标准是什么。
