摘要
道路密度是评价地区交通与经济发展的一项重要指标,也是实施"一带一路"互联互通倡议的基础工作。本数据集以OpenStreeetMap(简称为OSM)实时更新的道路矢量数据为基础,利用ArcGIS空间分析技术,以"一带一路"及其毗邻区域——亚洲、欧洲、非洲、澳大利亚和新西兰为研究区,分别计算了2016年10月公里网格尺度的公路和铁路道路网密度,并进行分析。本数据集为.tif存储格式,数量分别为1.56 GB和1.47 GB。该数据集可以直接反映"一带一路"及其毗邻区域道路分布状况,并为进一步的道路研究提供基础性数据。
Road&railway network density is one of the most important indexes to evaluate regional traffic and economic development,and is the foundation of implementing the interconnection and interworking proposal of the Belt and Road and Surround Region.Based on the real-time updated road vector data of Open Street Map and by Arc GIS spatial analysis technique,1 km resolution of road density and railway density was calculated and analysed over the Belt and Road and surround region—Asia,Europe,Africa,Australia and New Zealand in October 2016.The dataset was archived in.tif format with data size of 4.58 GB.The dataset can provide distribution of road and railway over the Belt and Road and surround region and provide basic data for future road and railway studies.
