Harnessing the potential of crowd sourcing for geospatial inventorying in disaster response using Open Source Geospatial Tools

what is it
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."

some examples
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.

Data(VGI) = Saves Time for Survey


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.
