Streets

The layer was developed historically for use in emergency response. Each segment represents a street centerline and has information about name, and emergency response information as well. The dataset is also used for network modeling purposes.本图层最初专为应急响应场景开发。每个线段对应一条街道中心线，包含街道名称及应急响应相关信息。该数据集同时可用于网络建模相关工作。
