Transcript Crowdsourcing and Disaster Management

Harnessing the potential of crowd
sourcing for geospatial inventorying
in disaster response using Open
Source Geospatial Tools
What is it?
• Crowdsourcing is the practice of outsourcing
tasks to a broad, loosely defined external
group of people. The idea is generally to
introduce new or more developed skill sets or
a larger work force to achieve some specific
goal.
• The term was first coined in 2006 by Wired
magazine author Jeff Howe in an article titled
"The Rise of Crowdsourcing."
Other Name of Crowd Sourcing in GIS
• Neo-Geography
• Volunteered Geographic Information
• Collaboration GIS
Some Examples
• Possibly, the earliest example of Crowd Sourcing is the
collection of words for the Oxford English Dictionary (OED).
In 1858, a group called the Philological Society contracted
with over 800 volunteer readers to collect words from all
available books and document their usages. Subsequently,
the group solicited broader public input and received over
six million submissions over the 70 years of the project.
• In 1936, Toyota held a contest seeking a new logo design.
The winning design from over 26,000 entries remained the
company's corporate logo until 1989.
• Wikipedia launched as a collaboratively written and edited
online encyclopaedia in January 2001. Free registration
enabled anyone to submit or edit an entry. The multilingual
site now hosts several million entries in English alone.

Disaster Management
• Natural Disaster.
• Man – Made Disaster.
Planning after Disaster Management
• Send team to ground for data collection
• Acquire data in proper format, distribute to
concerned department.
• Plan evacuation
• Send teams on ground.

Limitations
1. Non Trained Volunteers.
2. Data Authentications
3. Standards / Quality of Acquired Data
A homeowner who evacuated based on
information from an online map created by a
volunteer might be responding to a false
positive, and by waiting for officials, verified
information might have avoided the need to
evacuate altogether. But on the other hand the
delay in acquiring information from official
sources might have made the difference literally
between life and death.
