Opening Address Data around the World

With over 110 million points, OpenAddresses.io has grown to be the largest open database of address data in the world. Governments, developers and businesses are realizing that address data belongs in a commons where it can be easily maintained, used by all, and drive economic growth. These early efforts are now powering some of the world's best commercial geocoding systems, as well as crucial infrastructure like emergency responders. But there's more work to do. We need to reform outdated laws, expand coverage to new cultural contexts, untangle shortsighted licenses, and invent new modes of collaboration between the public and government. We'll cover how OpenAddresses started, how it can be used today, and how we expect it to grow into a definitive global resource.

Big data analysis with Tile Reduce and Turf.js

Tile Reduce is a new open source map reduce frame work for analyzing massive geo data. Tile reduce is a tile analysis framework built on the javascript GIS library Turf.js. It runs on your local computer or in the AWS cloud and scales to run thousands of processors in parallel. At Mapbox we use Tile Reduce to detect issues in global street vector data like OpenStreetMap, data comparison and data conflation. This talk will walk through the architecture of Tile Reduce, highlight advantages, limitations and future developments.
