  • 1. Collaborative Geospatial Collaborative Geospatial  Mapping & Public Licensing Mapping & Public Licensing Tyng-Ruey Chuang and Andrea Wei-Chi Tyng-R T Ch dA d Wei-Ching H W i Huang Institute of Information Science, Academia Sinica, Taipei, Taiwan At the GIS Application & Development Workshop by Taipei City Government Sep. 27‐28, 2007 , National Taiwan University, Taipei Taiwan    1 Preview for the Conclusion (I) : () • Most of you are likely to have known something about Most of you are likely to have known something about  the recent emerging Geospatial Web phenomenon, more  Geospatial  or less.  Web  • It is built on by non‐GIS professionals’ participation &  collaboration for the using of geoinformation in everyday  collaboration for the using of geoinformation in everyday Participation &  life.  Collaboration • The existing geodata has not been reusing effectively,  y g g the newly adding on geo‐information contributed by  y people’s collaboration has not been well managed.   Limitation • Privacy & Security Issues remain. (not discuss in this talk) 2
  • 2. Preview for the Conclusion (II) : ( ) • It is not a problem of technology It is a limitation of It is not a problem of technology. It is a limitation of  lacking of geodata to be able to be freely used on Web,  WHY and to be managed effectively. It is a question of policy. • The value of geodata is depends on its capacity of reusing  and recreating its usability by the public. The key issue is  and recreating its usability by the public The key issue is HOW the Public Licensing.  • The GeoCommons case study. The GeoCommons case study.  WHAT 3 Why  y Google Map/Earth, Yahoo, & Microsoft geo‐ mapping have done more valuable marketing for  pp g g GIS in one year than  the entire GIS industry has done its lifetime  y worldwide? Sep 6th 2007, The Economist Jack Dangermond( the founder of ESRI) says:  interest stimulated by the  geoweb has helped to boost GIS business by 20% in 2007.  Ron Lake (Galdos Systems) says: geobrowsers have led to a push for better  public access to geodata. Where 2.0, 2007 Di‐Ann Eisnor (CEO, Platial) : it is the economics of Mash‐ups which support &  leverage the open platform business model. And it is an early proving ground  leverage the open platform business model. And it is an early proving ground for distributed, collaborative value creation distributed, collaborative value creation. 4
  • 3. 1. Geospatial Web 1. Geospatial Web Through the browser, the geospatial  information become a new media on Web. 5 Online distributed participants  distributed participants are able to feel that they are  being in the same conference room, and can participate in  being in the same conference room and can participate in questioning and voting by sending text message.  6
  • 4. 2. Participation & Collaboration It is a Social Web plus online geospatial information.  It is a “You”, “Me”, and “We” Web.  It is a Geospatial Knowledge Mapping built by public participation & collaboration. 7 From desktop application to the Web  browser, from traditional GIS to the  geospatial mash‐ups in everyday life. 8
  • 5. 3. Limitations Existing geodata has not been reusing  effectively. ff l Geo‐information contributed by people’s  collaboration has not been well managed.   collaboration has not been well managed. 9 Technology is not a problem. Fi f Mi i Firefox Minimap adds a very rich feature geo‐sidebar to the browser. dd i hf t id b t th b drag & drop GeoRSS feed /KML from the Flickr tags into Minmap, and you can view a map of the Flickr photos 10
  • 6. Technology is not a problem. Tools like BRIGHTi GeoFeeder can convert vector data (points, lines & polygons)  from ESRI, Google, MapInfo, Autodesk, and GML file formats to GeoRSS xml. http://www.brightisolutions.com/ 11 Why an American company, Google, has made better  i f UK i practice of UK mapping than the UK's own mapping agency  h h UK' i (Ordnance Survey)? Why do many UK geo‐companies think their government‐ backed agency that should be their data provider but is often  regarded as a competitor? The answers of the Guardian on  March 16, 2006 & September 13, 2007 are that: The answers of the Guardian on March 16, 2006 & September 13, 2007 are that: “Nearly everyone agrees that electronic mapping is an important tool for public services.” “ the data that we pay to have collected (through our taxes), and which is then used by  the data that we pay to have collected (through our taxes) and which is then used by organisations such as the Ordnance Survey, is not freely available for re‐use  for re‐use by UK citizens.”  “We, and the companies that could benefit from its use, are forced to pay for it ‐ putting a  brake on the information economy.” b k h i f i ” http://society.guardian.co.uk/e‐public/story/0,,1731410,00.html 12 http://www.guardian.co.uk/technology/2007/sep/13/guardianweeklytechnologysection.freeourdata
  • 7. 4. GeoData Authorization “It's a question of the policy and the thinking  the policy and the thinking catching up with the  technology. says John Hanke, head of Google s Earth and Maps division in Sep  technology.” says John Hanke, head of Google's Earth and Maps division in Sep 6th 2007, The Economist. Geodata = Artistic work? Copyright? License ? Free? Privacy & Security? Pi &S i ? 13 •geo‐information  is a tool  g for empowerment of  citizens ; restriction of  using may contradict  the  government’s role •restricted data=  diminishing activities in  education & research d ti & h •sale data ≠ significant  revenue •open platform model as a  collected knowledge  economy ( google, eBay &  amozon ) amozon ) 14

The EU legislation now provides that the Copyright Designs and Patents Acts  (CDPAs) 3(1)(a)  a literary work includes  a literary work includes ‘a table or compilation  p other than a database’ 15 choices of public license for geospatial information  p g p are in hand  •GNU General Public License (source code  public releasing) bli l i ) •GNU Free Documentation License GNU Free Documentation License(for  documentation licensing) •Creative Commons Licenses (for general  content creation licensing) 16
  • 9. The Authorization Strategy for the sharing  and re‐use of geospatial data d f ld online, open, and collaborative exploration of domain  spaces is one of the most successful web paradigms.  flexible licensing models include : CC, GPL or dual  fl ibl li i d l i l d CC GPL d l licensing.  geospatial dataset release should be: geospatial dataset release should be: (1) in source forms ( ) (2) should be accompanied by the necessary data models  p y y (i.e., schema),  (3) metadata and catalog descriptions,  (4) data format definitions, and  (5) source code of the related software tools.  17 5. GeoCommons – geo‐datasets are fuel for mashups d f lf h GeoCommons is based on FortiusOne, a Washington, D.C. company. The public Beta is released on May  28th 2007 at  Where 2.0 Conference. . 18
  • 10. GeoCommons is to share – not just maps,  but data. • Users & data: U &d (1)allows users to set up an account & profile, and upload and  delete their datasets anytime. ( ) (2)users can make the map public or private, but datasets must  pp p , be public.  (3)registered users are provided with public URLs for their own  maps. • Data  & dataset : (1)It can be tagged, rated, commented on and searched.
