Volunteered Geographic Information (VGI) in the form of actively and passively generated spatial content offers extensive potential for a wide range of applications. Realising this potential however requires methods which take account of the specific properties of such data, for example its heterogeneity, quality, subjectivity, spatial resolution and temporal relevance. The creation and production of such content through social media platforms is an expression of human behaviour, and as such influenced strongly by events and external context. In this project we will develop geovisual analysis methods which show how actors interact in LBSM, and how their interactions influence, and are influenced by, their physical and social environment and relations. In the first phase of the project, we developed and demonstrated a conceptual model enabling the extraction, analysis and visualisation of events and reactions to events in location based social media (LBSM). A central element of this model and its implementation is the integration of spatial, temporal, thematic and social dimensions combined with an explicit link between events and reactions. The follow up project will concentrate on the development of methods allowing links to be made between reactions, human activities and emotions. Furthermore, the social and physical context of events, and the resulting influences on and from behaviour will form a central research element. The project will explore the representativity of LBSM and its limits with respect to a range of research questions and application fields. An important focus will be on the identification of relationships between different actors and events, supported by the use and further development of a broad palette of methods and workflows from the domain of visual analytics.As well as the development of generic approaches enabling comparative analysis using geostatistical and visual methods, we will refine, combine and parameterise methods for specific application domains. The focus here lies in three thematic areas to which the project consortium can bring experience and contact to partners from practice: 1) landscape and urban planning for the analyse and evaluation of green areas, 2) transport planning to explore group and individual mobility patterns and 3) political science through the application of comparative visual methods.

主动和被动生成空间内容形式的自愿地理信息 (VGI) 为广泛的应用提供了广泛的潜力。然而，要实现这一潜力，需要采用考虑此类数据特定属性的方法，例如其异质性、质量、主观性、空间分辨率和时间相关性。通过社交媒体平台创建和生产此类内容是人类行为的表达，因此受到事件和外部环境的强烈影响。在这个项目中，我们将开发地理视觉分析方法，显示行动者如何在 LBSM 中互动，以及他们的互动如何影响他们的物理和社会环境及关系，以及受其影响。在该项目的第一阶段，我们开发并演示了一个概念模型，能够提取、分析和可视化事件以及对基于位置的社交媒体（LBSM）中事件的反应。该模型及其实施的核心要素是空间、时间、主题和社会维度的整合以及事件和反应之间的明确联系。后续项目将集中于开发能够在反应、人类活动和情感之间建立联系的方法。此外，事件的社会和物理背景以及对行为的影响将构成中心研究要素。该项目将探讨 LBSM 的代表性及其在一系列研究问题和应用领域的局限性。一个重要的重点将是识别不同参与者和事件之间的关系，并通过使用和进一步开发可视化分析领域的广泛方法和工作流程来支持。除了开发能够使用地统计和可视化方法进行比较分析的通用方法外，我们还将针对特定应用领域完善、组合和参数化方法。这里的重点在于三个主题领域，项目联盟可以从实践中为合作伙伴带来经验和联系：1）用于分析和评估绿地的景观和城市规划，2）探索群体和个人流动模式的交通规划，3）通过应用比较视觉方法的政治科学。
