全球太阳能数据集
全球太阳能地图集的当前版本是2021年7月发布的2.6版。全球太阳能地图集2.0版是对最初在2016年发布的1.0版在线平台的增强，通过使用下载部分的GIS数据层和地图，提供对太阳能项目和场地进行初步评估所需的数据。本技术报告总结了GSA 2.0版本的交付情况，并将2.0版本与之前的1.0版本在方法、数据层和Solargis光伏发电模拟方法方面进行了比较。GSA 2.0提供了一个访问地球上几乎任何地点的长期平均年度（对于选定的参数每月）太阳能、空气温度、光伏发电潜力数据和地图产品。
该地图集提供了地球上几乎任何地点的长期平均年度（每月选定参数）太阳能、空气温度、光伏发电潜力数据和地图产品的访问。

数据结构
交付的GIS数据包括光栅数据层形式的八个参数，提供全球范围内的太阳能资源、光伏发电潜力、空气温度和地形高度等信息。
数据层以地理坐标系统（EPSG:4326）提供，并以30弧秒（名义上为1公里）的分辨率计算。在此基础上，为了更详细地分析太阳资源数据（GHI、DIF、GTI和DNI），也以9弧秒（名义上250米）的分辨率提供。最后，最佳角度特征的辅助数据层具有2角分（名义上是4公里）的分辨率。
