PV Rooftop Database

The National Renewable Energy Laboratory's (NREL) Photovoltaic (PV) Rooftop Database (PVRDB) is a lidar-derived, geospatially-resolved dataset of suitable roof surfaces and their PV technical potential for 128 metropolitan regions in the United States. The PVRDB data are organized by city and year of lidar collection. Five geospatial layers are available for each city and year: 1) the raster extent of the lidar collection, 2) buildings identified from the lidar data, 3) suitable developable planes for each building, 4) aspect values of the developable planes, and 5) the technical potential estimates of the developable planes.

美国国家可再生能源实验室（NREL）的光伏屋顶数据库（PVRDB）是一项基于激光雷达数据提取的、具有地理空间分辨率的适宜屋顶表面及其光伏技术潜力数据集，涵盖了美国128个都市地区。PVRDB数据按照城市和激光雷达数据收集年份进行组织。每个城市和年份提供五个地理空间层：1）激光雷达数据采集的栅格范围，2）从激光雷达数据中识别出的建筑物，3）每座建筑物的适宜开发平面，4）可开发平面的朝向值，以及5）可开发平面的技术潜力估算。
