LINKing and analyzing Volunteered Geographic Information (VGI) across different platforms
Public repository of the Link-VGI pre-conference workshop at AGILE2016.
14 June, 2016. Helsinki, Finland
The purpose of the hands-on session is to cover the basics of interacting with APIs and to extract summary statistics from the datasets acquired. All materials can be found in the Tutorial.
In order to connect to and export data from APIs, you will need to install some software components. Follow the guides found on this page to install components we are going to use during the hands-on session.
A number of examples require the use of APIs for acquiring data and often these require an API key to be provided. To save time in the practical it would be of benefit to sign up for and acquire an API key for the following services:
| Service | Registration address | API address | Parameters needed |
| ------- | -------------------- | ----------- | ---------------- ||
| Wheelmap.org | http://wheelmap.org/users/sign_in (it is actually OSM you need to register for) | Edit profile page | Authentication Token |
| Flickr |Yahoo (need to register for Yahoo or use a yahoo account) | Create a new application and then you can check on your account page under Your API keys| api_key, api_secret |
| Mapillary | http://www.mapillary.com/map/signup You need to create a Mapillary profile | Once logged in, navigate to http://www.mapillary.com/map/settings/integrations and hit Register an application. | api_key from Profile -> Integrations |
| Twitter | Sign up for Twitter | Go to Twitter Apps and hit Create New App. | api_key, api_secret |
| Instagram [optional] | Sign up for Instagram | Go to Instagram Developers and Register a new applications | client_id, client_secret |
If you do not want to sign up for these services, then there will be sample datasets made available, but obviously you will not be able to run the scripts to get data for an area of your choice.
