Hands-on Session: VGI data linkage:

Accessing, linking, and analyzing data from multiple platforms

The hands-on session will be presented and facilitated by Levente Juhász, Jamal Jokar Arsanjani and Adam Rousell

The first section intends to provide a brief overview of the basics of interacting with APIs that provide access to geospatial data. Several examples will be given to illustrate client authentication, making data requests, exporting data to standardized geospatial formats and importing data in a statistical modeling environment (R). This section will use the public APIs of OpenStreetMap (OverpassAPI), Twitter, Instagram, Mapillary, Flickr and Wheelmap.

The second section is a detailed Case study around the topic of accessibility. It intends to provide a more detailed assessment of the accessibility of popular locations based on data from Flickr, Wheelmap, Instagram, Mapillary and Foursquare. The exercise will use VGI photos and POI information as a proxy to popular locations.

All materials which participants will require will be made available on GitHub (link to appear in the next few days)

Workshop participants can take part using their own laptop. Please ensure that your laptop can connect to the AGILE conference WiFi and that you have appropriate permissions to install software on your laptop. Unfortunately we are not in a position to offer access to laptops or desktop computers for these sessions.
