Mapping Social Media
GIS and Social Media
GIS
A tool for examining
geographic knowledge
to better understand
our world
Social Media
YouTube
Flickr
GIS and Social Media
• Social Media = Another source of geographic data
• Provides another means to better understand our world
Build maps using ArcGIS.com
Link map in Facebook or Twitter
Embed web map inside a blog
Development skills are NOT REQUIRED
Development paths
Build applications using the ArcGIS Web APIs
Display georeferenced locations of events
Interactively display media content
Development skills are REQUIRED
Sharing web maps using
social networks
Integrating data harvested by
social networks into maps
Create a Map on
ArcGIS.com
1
Share your
Map in a
blog or via
Social
Networking
2
Download API’s &
templates from
ArcGIS.com
1
Scrape data from
Twitter, YouTube
2
Create a custom
Web Application
3
Share maps with social media
Email a URL to a web map
Share with social networks such as Facebook
and Twitter
Embed your map into your own website
Website templates are made available by Esri
to create your own web application!
The Social Media APIs
• Examples of APIs you can use to integrate with your GIS maps
Twitter Search API
Twitter Streaming API
Twitter Trending API
Flickr API
Facebook Foursquare
YouTube Data API
Others: e.g. Gnip
Social media maps - Examples
• Earthquakes <link>
• Severe Weather <link>
• Hurricanes and Cyclones <link>
• Global Incident Viewer <link>
• Current Event Maps <link>
• Horn of Africa Drought <link>
• Libya Unrest <link>
…based on the Public Information templates…
• Flooding <link>
• Wildfires <link>
Demonstration I
• Displaying your Web apps using social media
• Exploring examples of GIS and social media
Review and Questions
• Displaying your Web apps using social media
• Exploring examples of GIS and social media
Volunteered Geographic
Information
What is VGI?
• Volunteered Geographic Information
• Locational Crowdsourcing
• Citizens contributing geographic data
• Examples of VGI
• Crisis mapping
> Source of geographic data during emergencies
• Gather data at a lower cost
• Citizen request maps
> Engages citizens in their community
How to use VGI?
• Can be used as a source of geographic data because of its timeliness
• Think about the time it takes to create authoritative data
• Think about how out-of-date authoritative data can be when it first hits the shelves
• Now compare that to how immediate your need can be for current, geographic data
Lessons Learned
• What about data accuracy?
• Linus’s Law
• Tobler’s Law
• Can I trust it to be true, honest, and quality input?
• Filtering mechanisms
• Community Policing
• Can this method replace my existing workflow?
• Can it be trusted?
• Is this method dependable?
Demonstration II
• Exploring examples of VGI applications
• Wikimapia
> wikimapia.org
• OpenStreetMap
> openstreetmap.org
• Ushahidi
> ushahidi.com
• Crowdmap
> crowdmap.com
Review and Questions
• Exploring examples of VGI applications
Public Information
Templates
VGI, Social Media and Content
VGI
Citizen volunteers
contributing
geographic data
Social Media
Turning the public’s
conversation into
geographic data
Authoritative Content
Geographic data
generated and maintained
by GIS professionals
…imagine the power of using them together…
Public Information Templates
• Available at the ESRI Resource Center
• Can be used to gather data at a lower cost
Public Information Templates
• Public Information Map
• Built with ArcGIS API for JavaScript
• Based on ArcGIS Online basemap
• Zip file with application, copy to Web server
• Easy to make simple configuration changes
• Public Information Center
• Built with ArcGIS API for JavaScript
• Based on sample data, plug in your own data
• Zip file with application, mxds, sample data
• Follow the documentation to set up the application
…work with the Social Media APIs to access social media content…
Example: Twitter Search API
• Read the API documentation
• dev.twitter.com/docs/api/1/get/search
• Build a GET request to URL to make a search
• search.twitter.com/search.format
• Incorporate parameters to narrow the search
> q, geocode, page, rrp
• Write code to handle the response
Examples: YouTube & Flickr
• YouTube Data API
• gdata.youtube.com/feeds/api/videos
> Key Parameters: q, location, location-radius, time
• Flickr API
• api.flickr.com/services/rest/?method=flickr.photos.search > Key Parameters: api_key, tags, min_date_taken,
max_date_taken, bbox, accuracy, has_geo, lat, long, radius, radius_units, per_page. page
Lessons Learned
• Mashing up social media content can be tricky
• You never know what you are going to get
• Know how to get the most from your request
• Things can change at any time
• Know your rights!
• “Enhance your calm”
