【摘要】：周边区域地理信息的获取是我国地缘环境研究中的一个难题,志愿者地理信息(volunteered geographic information,VGI)的兴起为解决该难题提供了一个可行的方法。在目前一系列的VGI项目中,OpenStreetMap(OSM)是比较领先的应用,但OSM数据模型不同于我国周边应用的专业矢量数据模型,因此,利用OSM数据时首先需要对其进行模型转换。有鉴于此,本文提出了一种基于规则的OSM数据到专业应用矢量数据模型转换方法。该方法首先利用OSM定义的几何类型与地物属性作为分类依据,建立了模型转换基本规则库;对于志愿者根据自己的理解自行标注未包含在基本规则库中的目标采用人机交互方式进行模型转换,并在此过程中不断完善规则库,利用越南与巴基斯坦数据进行实验,最终形成了包括2 344条转换规则的模型转换规则库,为OSM数据模型到专业应用矢量数据模型的转换提供了一条可行途径。
[Abstract]:The acquisition of geographical information in peripheral regions is a difficult problem in the study of geo-environment in China. The rise of volunteer geographic information has provided a feasible method to solve this problem.OpenStreetMapOSM is a leading application in a series of VGI projects at present, but the OSM data model is different from the professional vector data model in the peripheral application of our country. Therefore, it is necessary to transform the OSM model first when using OSM data.In view of this, this paper proposes a rule-based transformation method from OSM data to professional application vector data model.In this method, the basic rules of model transformation are established based on the geometric types and the attributes of objects defined by OSM.According to their own understanding, volunteers annotate objects that are not included in the basic rule base and use human-computer interaction to transform the model. In the process, they constantly improve the rule base and make use of Vietnamese and Pakistani data to carry out experiments.Finally, a model transformation rule base including 2 344 transformation rules is formed, which provides a feasible way for the conversion of OSM data model to professional application vector data model.
