2016年长株潭1：5万交通规划省道数据

数据由湖南省交通运输厅科技信息中心提供，以矢量的形式存在。长株潭地区2016年省道的规划路线矢量数据，包括路段类型、起点桩号、终点桩号、路段编码等属性信息。通过这些属性信息能够高效的提取不同等级、不同类型的道路，同时支持不同区间桩号的特定道路选择。

The data is provided by the Science and Technology Information Center of the Department of Transportation of Hunan Province, and is stored in vector format. It is the vector data of planned provincial highway routes in the Changsha-Zhuzhou-Xiangtan region in 2016, including attribute information such as road segment type, starting stake number, ending stake number, and segment code. These attributes enable efficient extraction of roads of different grades and types, and support the selection of specific roads within specified stake number intervals.
