  1. Introduction to Crowdsourcing & Web Mapping

  2. Agenda • Citizen Mapping • OpenStreetMap • Google Map Maker • Google Earth

  3. Crowdsourcing Crowdsourcing is the process of getting work, usually online, from a crowd of people. The word is a combination of the words 'crowd' and 'outsourcing'. The idea is to take work and outsource it to a crowd of workers. Famous Example: Wikipedia. Crowdsourcing & Quality: The principle of crowdsourcing is that more heads are better than one. By canvassing a large crowd of people for ideas, skills, or participation, the quality of content and idea generation will be superior. http://dailycrowdsource.com/

  4. Crowdsourcing is simply asking somebody to do something! You have contributed to crowdsourcing, if you have: - answered a question - made a correction or submission - told a story - answered a survey - voted, tagged, commented Crowdsourcing using maps is also commonly known as Citizen Mapping

  12. Google Earth

  13. Google Earth • Source for information on land and people • Archaeological information • Social and cultural information • Urban and commercial development • Geographical information • Natural disasters and restoration • Earthquake tracking and projections • Mapping! Simple and advanced • Georeferencing photos and maps – higher resolution or historical • 3-D Model building – (infrastructure planning) • Virtual biographies • Navigation and quickest routes

  14. Google Earth and Planning • Using imagery to evaluate city grid and street planning • Urban development over time • uWaterloo development over time

  15. From his office chair in Perth, Professor Kennedy has remotely identified thousands of archaeological sites without having to step foot on Saudi Arabian or Yemeni soil. Historically it has been difficult to undertake ground surveys and aerial photographs of these areas are seldom available for research, making the countries some of the least explored archaeologically. • By carefully studying satellite imagery of the Arabian peninsula in Google Earth, Professor Kennedy has unearthed an enormous record of archaeological sites, from ancient geoglyphs to stone Wheels to Pendant-shaped tombs and animal traps called kites that could be up to 9,000 years old.
