Open Data
The idea that certain data should be● freely available to everyone to use ● and republish as they wish, ● without restrictions from copyright, patents or
other mechanisms of control.
● Open Data could be textual just like Wikipedia.
● Or non-textual, such as maps, genomes, connectomes, chemical compounds, mathematical and scientific formulae, medical data and practice, bioscience and biodiversity.
Open Data
Open Data
● "Data belong to the human race".● Public money was used to fund the work and
so it should be universally available.● Facts cannot legally be copyrighted.● In scientific research, the rate of discovery is
accelerated by better access to data.
Open Data / The "Open" Concept
● Open access● Open research/Open science/Open science
data● Open knowledge● Open Source
Open Data / In Government
● data.gov● data.gov.uk (Hail to Sir Tim Berners Lee)● data.govt.nz● opengovdata.ru
Open Data Institute
● Established by Tim Berners-Lee & Prof. Nigel Shadbolt.
● Catalyses the evolution of an open data culture to create economic, environmental, and social value.
Crowdsourcing
● Genesis of crowdsourcing can be taken as the start of open source movement.
● The new media: Content is created by amateurs.
● People come together to perform tasks, usually for little or no money.
Crowdsourcing
● Not a product of an economist or management consultant or marketing guru.
● Arose out of the uncoordinated actions of people, who were doing things that people like to do, in the companionship of other people.
Crowdsourcing
● Labor can be organized more efficiently in communities than corporations."The best person to do a job is the one who wants to do it most."
● "Given the right set of conditions, the crowd will always outperform any number of employees." (Jeff Howe, Crowdsourcing, 2009)
Crowdsourcing
● Contrary to the general opinion that the internet isolates people from each other, crowdsourcing uses this medium for collaboration and sharing between people from any background in any geographical location.
● Contrary to conventional wisdom, people do not always behave in self-interested patterns.
Crowdsourcing
● Companies abandon their tech-support departments and replace them with user forums.
● CNN, BBC, Gannett, Reuters, etc. have started to crowdsource local events internationally instead of assigning professionally trained journalists.
● Crowdsourcing is not cheap labour nor a free ride! All successful crowdsourcing efforts share deep commitment from the user base.
Crowdsourcing
It is the mechanism by which such talent and knowledge is matched to those in need of it.
Reliability of crowdsourcing?

Map

A map is the scaled, symbolized
representation of a region of the Earth projected onto a planar surface.
OpenStreetMap
● 2004, Steve Coast (University College London)
● Influenced by the success of Wikipedia and the access restrictions to the British Ordnance Survey archives.
● Is basically a large spatial database operating on ODBL (Open Database License)
● First users and contributors were mainly bikers tracking their biking routes.
OpenStreetMap
www.openstreetmap.org
● OpenLayers-based slippy user interface.
● Maps are displayed as tiles generated by Mapnik rendering engine.

Be careful about your data sources!!!
● Copyright infringement must be avoided when contributing to OpenStreetMap.○ Using data sources which are not provided in OSM
editors (JOSM, Potlatch, etc.) should be avoided.
● e.g.: Legal terms of Google does not allow data production using Google Maps and Google Earth.○ Trap streets!!
Worldwide Events:
● Mapping Parties
Mappy Hour (Toronto)
● Developer MeetingsHack Weekends (London, Karlsruhe, Toronto, etc.)
● Conferences, WorkshopsState of The Map, Geoinformatik

Humanitarian OSM Team
● Launched in 2009○ Aim to connect humanitarian actors and open
mapping communities○ Remote data creation during crises ○ Promote crowdsourcing and simple web standards
for data sharing

Why Weak in Turkey?
● Conception of "free!"
● Monopolistic behavior"I want to own and control the data."
● Most people still believe in myths & conspiracy, such as "free and open source is not secure".
What now?
● Extend the user-base
● Socialize○ Mapping Parties○ Hack Days
● Educate (Academic OSM Initiative of Turkey)
● Collaborate (NGO, GO, Private Sector)
