1. Perception

We present an introduction into modern geography theory, where we dive into specific areas of the geography literature that are particularly relevant to the WWW audience. We further describe how machines commonly represent geographic data and how humans in turn perceive this data. This includes discussions on how people discuss and create places beyond simple coordinate reference systems.

2. Analytics

We first cover basic techniques for operating on geotagged data, such as determining the distance between geographic coordinates, and computing areas of and overlaps between polygons. We then move to more advanced techniques, such as clustering and density estimation. We particularly show how geotagged data differs from traditional data and thus often requires special considerations in order to obtain reliable output, such as understanding which statistical techniques are (not) appropriate.

3. Visualize

We cover a variety of techniques the attendees can use to visualize and explore actionable insights from geotagged data. A hands-on session will let the attendees first interact with real geotagged data to get familiar with visualizing a number of data representations using projections, and then present several use cases for them to investigate using suitable techniques.
