Wrangling Trillions of Pixels with Open-Source Tools

We’re continuously building a comprehensive raster map of the world. We use imagery from dozens of providers, delivered in several ways, at scales from hemispheres to trampolines. In this talk, we’ll show some of the ways we use (and create) open-source tools to integrate terabytes of heterogeneous raw data into a single, constantly improving image of Earth. We’ll cover topics from ways of dealing with nodata values to how we pursue aesthetics, driven by real examples with lots of beautiful images. We will discuss some details of tools like numpy and rasterio, but most material will be accessible to any FOSS4G attendee.
