The study of geographical systems as graphs, and networks has gained significant momentum in the academic literature as these systems possess measurable and relevant network properties. Crowd-based sources of data such as OpenStreetMaps (OSM) have created a wealth of worldwide geographic information including on transportation systems (e.g., road networks). In this work, we offer a Geographic Information Systems (GIS) protocol to transfer polyline data into a workable network format in the form of; a node layer, an edge layer, and a list of nodes/edges with relevant geographic information (e.g., length). Moreover, we have developed an ArcGIS tool to perform this protocol on OSM data, which we have applied to 80 urban areas in the world and made the results freely available. The tool accounts for crossover roads such as ramps and bridges. A separate tool is also made available for planar data and can be applied to any line features in ArcGIS.
将地理系统作为图和网络进行研究在学术文献中得到了很大的关注,因为这些系统具有可测量和相关的网络属性。基于众包的数据来源,如 OpenStreetMaps(OSM),创建了大量的全球地理信息,包括交通系统(例如,道路网络)。在这项工作中,我们提供了一个地理信息系统(GIS)协议,将折线数据转换为可操作的网络格式,包括节点层、边层以及带有相关地理信息(例如,长度)的节点/边列表。此外,我们还开发了一个 ArcGIS 工具来执行 OSM 数据上的这个协议,我们已经将其应用于全球 80 个城市,并免费提供结果。该工具考虑了交叉道路,如匝道和桥梁。还提供了一个用于平面数据的单独工具,可以应用于 ArcGIS 中的任何线要素。
