Loudoun Major Power Lines
收藏资源简介：
More Metadata Major Power Lines are used to show the spatial location of major high tension overhead power lines in Loudoun County, VA. This feature class/shapefile is for the Homeland Infrastructure Foundation Level Database (HIFLD) https://gii.dhs.gov/HIFLD as well as the Energy modelling and simulation community and contains Electric Power Transmission lines in the U.S. greater than or equal to 100 volts. It has been modified to include new line additions built after the dataset was published. Dataset was modified in February 2025 to include transmission line segments that have been approved by Virginia’s State Corporation Commission (SCC) but not built. Update Frequency: Not expected to be updated unless a new power line is built or approved. Date of last update: February 2025
「主要高压输电线路」元数据补充说明：本数据集用于展示美国弗吉尼亚州劳登县境内主要高压架空输电线路的空间分布位置。该要素类（feature class）/形状文件（shapefile）可服务于国土基础设施基础层级数据库（Homeland Infrastructure Foundation Level Database，HIFLD，https://gii.dhs.gov/HIFLD）及能源建模与仿真社区，收录美国境内电压等级不低于100伏特的电力输电线路数据。本数据集已完成更新，纳入了数据集发布后新建的输电线路。本次更新于2025年2月完成，新增纳入经弗吉尼亚州州公司委员会（State Corporation Commission，SCC）批准但尚未开工建设的输电线路区段。更新频率：若无新建或获批的输电线路项目，预计不会进行更新。末次更新日期：2025年2月
