Powerline Corridors in the Western United States and Canada
收藏资源简介:
Powerlines in the western United States and Canada as identified by the 22 source data layers used to compile this shapefile. Source data were collected by personal contact or through the internet in the winter and spring of 2004 and assimilated using ArcGIS. This file is a complete record of overhead powerline data that was available as of 5/15/2004 but IS NOT INTENDED TO BE A COMPLETE REPRESENTATION OF THE SUM TOTAL OF ALL POWERLINES ON THE GROUND. These data primarily depict the higher voltage, long distance transmission lines but some arcs likely represent lower voltage distribution lines.
本形状文件(Shapefile)基于22个源数据图层编译而成,收录了经上述图层识别的美国西部及加拿大境内的架空输电线路。源数据采集于2004年冬春两季,采集途径包括人工联络与互联网检索,并通过ArcGIS完成数据同化。本文件完整记录了截至2004年5月15日可获取的全部架空输电线路数据,但并非旨在完整覆盖地面上所有输电线路的实际总量。该数据集主要呈现高压、长距离输电线路,但部分弧段大概率对应低压配电线路。
