EnergyGrid_legAmazon_WGS84.prj

The electrical grid in the Legal Amazon of Brazil was hand-digitized in ArcGIS by tracing the path of transmission lines detected using 2017 ESRI World Imagery (pixel size varying from 10-30 m resolution, depending on the location). We visually inspected images covering the entire Legal Amazon, starting from publicly available datasets of transmission lines and power generation plants. Once a line was located, it was traced to its origin at a substation or power source. From there, we located and traced other lines that originated at the same source. Since all lines originate at a substation or generation plant, this was an effective way to ensure the entire region was searched. All visible transmission and distribution lines were recorded, regardless of size or voltage, including instances where the lines themselves were visible or only the posts or towers that support the transmission lines were detected. Distribution lines within cities were not typically included, as they were extremely difficult to detect. This dataset is in WGS84.<br>Contact me at [e-mail] with inquiries!巴西法定亚马逊区域（Legal Amazon）内的电网数据集，通过ArcGIS软件手动数字化2017年ESRI世界影像（ESRI World Imagery）中识别的输电线路路径，该影像的像素分辨率因区域不同介于10-30米。研究团队以公开的输电线路与发电厂数据集为基础，对覆盖整个法定亚马逊区域的影像开展目视解译。定位到单条线路后，将其追踪至所属变电站或电源起点；随后以此起点为基准，定位并追踪所有由此衍生的线路。由于所有线路均起始于变电站或发电厂，该方法可有效确保完成全区域的排查覆盖。本数据集收录所有可见的输电与配电线路，无论其尺寸或电压等级，涵盖线路本体可见、仅能识别输电杆塔两类场景。城市内部的配电线路通常未被纳入数据集，因该类线路极难通过影像识别。本数据集采用WGS84坐标系。 如有咨询，请致邮[e-mail]。
