Speedtest by Ookla Global Fixed and Mobile Network Performance Maps

Global fixed broadband and mobile (cellular) network performance, allocated to zoom level 16 web mercator tiles (approximately 610.8 meters by 610.8 meters at the equator). Data is provided in both Shapefile format as well as Apache Parquet with geometries represented in Well Known Text (WKT) projected in EPSG:4326. Download speed, upload speed, and latency are collected via the Speedtest by Ookla applications for Android and iOS and averaged for each tile. Measurements are filtered to results containing GPS-quality location accuracy.

全球固定宽带和移动（蜂窝）网络性能数据，按16级Web Mercator瓦片进行分配（在赤道附近约为610.8米乘以610.8米）。数据以Shapefile格式以及Apache Parquet格式提供，几何形状以Well Known Text（WKT）表示，并投影至EPSG:4326坐标系。下载速度、上传速度和延迟是通过Ookla公司的Speedtest应用在Android和iOS平台上收集的，并对每个瓦片进行平均。测量结果经过筛选，仅包含GPS级位置精度的结果。
