Using OpenStreetMap data in QGIS

Using OpenStreetMap data in QGIS

Presentation by Keith Jenkins at FOSS4GNA 2018 St. Louis

SLIDES: https://kgjenkins.github.io/foss4gna2018

Over the years, OpenStreetMap (OSM) has established itself as the most complete global dataset of road data, as well as a great source for other features like building outlines and points of interest. Its open data license has allowed third-party developers to create numerous tools for extracting, processing, and repackaging OSM data in a variety of formats. But with so many options, it can be difficult to keep up as new tools are created, and others are retired.

This talk will give an overview of the many different ways to acquire and use OSM data within QGIS. We'll explore different sources and formats of OSM data extracts, and why you might choose one over another. We'll investigate the mystery of what happens to all those OSM tags during the conversion process. We'll discover some ready-made QGIS styles that can be used to render beautiful OSM data. We'll see various designs of pre-rendered OSM-based map tiles that can be used as base layers in QGIS. And we'll assess the current state of OSM-related plugins for QGIS 2 and QGIS 3.
