摘要

行人网络信息在基于行人定位服务（LBS）中起着重要作用，其完整性决定了行人LBS的质量。本研究利用自愿数据和百度地图研究了如何基于行人GPS轨迹提取行人网络信息。该方法通过三个步骤提取人类道路信息：清理轨迹数据、提取道路网络以及检测和分析识别出的步行道路设施。一旦提取了道路网络信息，就可以获得关于道路设施的信息，例如，人行横道、立交桥和地下通道。本文描述了一种增量更新电子地图的新方法。

Pedestrian network information extraction based on VGI

Pedestrian network information plays an important role in pedestrian location based service (LBS), and its completeness determines the quality of a pedestrian LBS. This study used volunteered data and BaiduMap to research how to extract pedestrian network information on the basis of pedestrian GPS trajectories. The method extracts human road information by three steps: cleaning track data, extracting the road network, and detecting and analysing the recognised pedestrian road facilities. Once the road network information is extracted, the information regarding road facilities can be obtained, e.g., pedestrian crossings, overpasses, and underground passages. This paper describes a new method for incrementally updating electronic maps.

期刊介绍： Geomatica (formerly CISM Journal ACSGC), is the official quarterly publication of the Canadian Institute of Geomatics. It is the oldest surveying and mapping publication in Canada and was first published in 1922 as the Journal of the Dominion Land Surveyors’ Association. Geomatica is dedicated to the dissemination of information on technical advances in the geomatics sciences. The internationally respected publication contains special features, notices of conferences, calendar of event, articles on personalities, review of current books, industry news and new products, all of which keep the publication lively and informative.
