This equates to a tile that is approximately 610.8 meters by 610.8 meters at the equator (18 arcsecond blocks). As such, tile size varies slightly depending on latitude, but tile sizes can be estimated in meters.įor the purposes of these layers, a zoom level of 16 (z=16) is used for the tiling. By this definition, tile sizes are actually some fraction of the width/height of Earth according to Web Mercator projection (EPSG:3857). This tile-splitting continues as zoom level increases, causing tiles to become exponentially smaller as we zoom into a given region. At z=1, the tile is split in half vertically and horizontally, creating 4 tiles that cover the globe. At z=0, the size of a tile is the size of the whole world.

The size of a data tile is defined as a function of 'zoom level' (or 'z'). In order to create a manageable dataset, we aggregate raw data into tiles. Hundreds of millions of Speedtests are taken on the Ookla platform each month. Ookla hopes to further this mission by distributing the data to make it easier for individuals and organizations to use it for the purposes of bridging the social and economic gaps between those with and without modern Internet access. Ookla licenses data to NGOs and educational institutions to fulfill its mission: to help make the internet better, faster and more accessible for everyone. Government regulators such as the United States Federal Communications Commission and the Malaysian Communications and Multimedia Commission use Speedtest data to hold telecommunications entities accountable and direct funds for rural and urban connectivity development. Speedtest data is used today by commercial fixed and mobile network operators around the world to inform network buildout, improve global Internet quality, and increase Internet accessibility. Measurements are filtered to results containing GPS-quality location accuracy. Download speed, upload speed, and latency are collected via the Speedtest by Ookla applications for Android and iOS and averaged for each tile. Data is provided in both Shapefile format as well as Apache Parquet with geometries represented in Well Known Text (WKT) projected in EPSG:4326. This dataset provides global fixed broadband and mobile (cellular) network performance metrics in zoom level 16 web mercator tiles (approximately 610.8 meters by 610.8 meters at the equator).
