RoughMaps：室内符号地图服务平台

RoughMaps：A Generic Platform to support Symbolic Map Use in Indoor Environments

      许多应用都需要能够支持个性化和上下文感知信息。其中用户定位和地图主要作用就是为了满足这个目的。RoughMaps平台包含了符号地图的功能。这种地图不需要考虑比例尺，是一种非线性、以自然的形式高度抽象的地图，仅仅包含了给定用户当前情境所需求的相关地图要素。文中介绍了RoughMaps平台的设计、实现和测试工作。该平台可用于根据上下文进行管理和查询面向室内定位的符号地图。据了解，该平台是个性化上下文感知应用中第一个支持室内定位的符号地图平台。

     An important feature for many applications is the ability to support personalised and context-aware information delivery. User positioning and the use of maps are essential for this purpose. The RoughMaps platform accommodates the use of symbolic maps, which are often not-to-scale, non-linear, highly abstract in nature, and which often contain only the most salient and most relevant features of a map based on the immediate needs of a given user. This work describes the design, implementation, and validation of the RoughMaps research platform, for managing and retrieving contextually relevant symbolic maps for indoor positioning. This is to our knowledge one of the first platforms that focuses on the use of symbolic maps to support indoor positioning in personalised and context-aware mobile applications.
