全球1:100万交通分布数据(2013年)
收藏资源简介:
全球1:100万交通分布数据(2013年)以国际公开的全球交通数据为本底数据进行加工集成。数据本身存在缺失道路所在国家和地区属性缺失、主要高速公路、其他道路与中国实际高速分布状况不符,或二者分布存在偏移和断线等问题。针对这些问题,参考全球行政区划数据为道路数据赋上所在国家和地区值,参考国家测绘与地理信息局制作的中国交通分布数据(包含高速公路和一般道路)对全球交通分布数据逐个进行人工手动检查、修正,最终形成一套完整的全球交通分布数据。
The 2013 global 1:1,000,000-scale traffic distribution dataset was developed by processing and integrating internationally publicly available global traffic baseline data. The original dataset contained several quality issues: missing country and region attributes for some roads, discrepancies between the distribution of major highways and other roads in the dataset and China's actual highway distribution, as well as distribution shifts and broken road links across the dataset. To resolve these problems, we first assigned country and region attributes to the road records using global administrative division datasets as a reference. Next, we performed manual inspection and correction for every entry of the global traffic distribution data, with reference to China's traffic distribution data (covering highways and general roads) compiled by the National Administration of Surveying, Mapping and Geoinformation. Ultimately, a complete and standardized global traffic distribution dataset was finalized.
