BDTRE — Road element (EL_STR)

It belongs to the theme “Roads”.The “road” is identified as the area for public use intended for the circulation of pedestrians, vehicles and animals. The theme describes both the main and secondary mobility areas and the corresponding graph representation. Defines the street graph element at the level of detail, corresponds in the GDF standard to the road element of the level 1 graph (element road). It is the synthesis of the VEICOLARE CIRCULATION AREA for the “track track” and “structured traffic area” or “unstructured traffic area”.The road element has as its constraint that it is within the road area that summarises.The data can be used individually through the use of the WFS service relating to the corresponding priority stratum through the on-line resource indicated on the parent metadata (BDTRE — Territorial Reference of Entity Data Base).本数据集归属“道路（Roads）”主题。其中“道路”被定义为供行人、车辆及动物通行的公共使用区域。该主题涵盖主次通行区域及其对应的图结构表示。本数据集在细节层级定义街道图元，在通用数据格式（General Data Format，GDF）标准中对应一级图的道路图元（road元素）。其为“track track”区段、“结构化交通区域”或“非结构化交通区域”所对应的车辆通行区域（VEICOLARE CIRCULATION AREA）的合成体。道路图元的约束条件为：其需处于上述汇总的道路区域范围内。用户可通过父元数据（BDTRE — 实体数据库领土参考）中指明的在线资源，调用对应优先级层级的网络要素服务（Web Feature Service，WFS），实现该数据集的单独使用。
