Mobile map applications based on user generated content for cartographic communication

地理信息处理领域正在进行的技术发展对制图信息的处理和互动产生了巨大影响。随着空间数据的获取以及在各种输出媒体上展示地图，这一点变得显而易见。在移动的设备上的制图应用具有巨大的研究和开发潜力，因为它们提供了交互性和移动性相结合的扩展到纸质地图，从而允许自适应的个性化信息交换。该研究项目的主要目标是开发基于服务的软件组件，用于创建交互式移动的地图。使用的例子将是为瑞士萨克森州试点地区的旅游活动提供空间信息服务。在Web2.0环境下，用户越来越多地提供对分布式、异构数据源的访问。该项目的主要重点是使用语义网技术，特别是用于空间数据建模和存储的资源描述框架。分层数据结构和用于真实的-时间综合的方法应应用于尺度相关的自适应地图的自动推导。基于这些方法，将支持准连续缩放以及去除局部重叠冲突。此外，还必须开发和实施交互式技术，使用户有可能控制所提供的信息量和地图显示风格。因此，该项目有助于自适应移动的地图展示领域的基础研究，从而使用户成为制图通信过程中的中心位置。

The ongoing technological development in the domain of geoinformation processing has a huge impact on the handling of and interaction with cartographic information. This becomes obvious with the capturing of spatial data, as well as with the presentation of maps at a variety of output media. Cartographic applications on mobile devices have enormous research and development potential, because they provide the combination of interactivity and mobility in extension to paper maps, thus they allow an adaptive, personalised information exchange. The main goal of this research project is the development of service‐based software components for the creation of interactive, mobile maps. The example of use will be the provision of spatial information services for tourist activities in the pilot region Saxon Switzerland. The access on distributed, heterogeneous data sources is essential which are provided increasingly by the user in the Web2.0. The main focus in the project is given to the usage of semantic web technologies, especially the Resource Description Framework (RDF) applied to the modelling and storage of spatial data. Hierarchical data structures and methods for real‐time generalisation should be applied for the automated derivation of scale dependent, adaptive maps. Based on these methods quasi‐continuous zooming will be supported as well as the removal of local overlapping conflicts. Furthermore interactive techniques has to be developed and implemented, which provides the possibility to control the amount of presented information and the cartographic presentation style by the user. As a result the project contributes to the basic research in the area of adaptive, mobile map presentation, whereby the user becomes a central position within the cartographic communication process.
