Parts 3 and 4 of a comprehensive look at the Geoweb, based on well defined web2.0 patterns and examples as well as organice buzz within the Geoweb community. For a detailed summary, see http://blog.gishacks.com/2009/09/comprehensive-look-at-geoweb-part-3-and.html.

9. What Do You Think? “spatially enabled and access over the internet” “complete integration and use of location at all levels of the Internet and the Web” Before this course: “simply as interactive maps published on the internet, through platforms such as ArcIMS or simple web enabled flash maps” “digital representation of the real world” “internet technologies to get and share geospatial information” “massive community of applications” “kids would use to learn geography”

19. “An ecosystem is a natural unit consisting of all plants, animals and micro-organisms (biotic factors) in an area functioning together with all of the physical (abiotic) factors of the environment. Ecosystems can be permanent or temporary. An ecosystem is a unit of interdependent organisms which share the same habitat. Ecosystems usually form a number of food webs…” (Ecosystem, 2009)

28. Spatial Data Infrastructure (Public display of this image is not permissible.)

29. Barriers To Data Sharing: At Least the SDI Approach “Geodata.gov is the worst example of data sharing available” “Finding stuff with a map is the way to go” “Time to kill metadata” “Information for the casual user” “Geoportals don’t work because they are created by experts for experts” “Comes down to GeoZen” “Metadata should be machine created” (Fee, 2009)

36. “Since internet users now have a myriad of choices in where they go for information, we as professionals should be designing highly usable systems that give users relevant information…and give it to them right now. If we don’t, they’ll simply go somewhere else.” (Noyle, 2009)

39. Flex JavaScript WMS JSON REST AJAX GeoRSS KML Design

40. Turner’s Characterization of Geoweb formats Shapefiles Microformats (geo) (XML) GeoRSS (XML) KML (XML) GeoJSON GML Others (GeoPDF, JPEG2000) Service Standards (Interfaces) WMS, WFS, SOAP, OpenSearch-Geo, RESTful style (Turner, 2009)

41. Formats as Representation Resources (Map) SOAP WMS WFS HTTP Goodness (RESTful) Representations of a resource GeoJSON GML JPEG2000 KML GeoRSS JPEG2000

42. “GeoRSS, KML, and GeoJSON are the itching powder, squirting ink pen, and dribble cup of geodata formats.”– Sean Gillies (Turner, 2009)

43. Common Web 2.0 Patterns Influencing the Geoweb Service Oriented Architecture (SOA) Software as a Service (SaaS) Participation-Collaboration Asynchronous Particle Update Mashup Rich User Experience Collaborative Tagging Structured Information Formulated By Real Examples….

44. SOA Debate for the Geoweb REST SOAP “Is the web” Bottom up approach Organic Stateless, cacheable, layered, linked URI based resources Multiple formats (not just xml) Bookmarkable Portable Performance Simple “SOAP You Can Trust” It has been around and has been used Standards oriented It works Top down approach Contract oriented Complex Robust Secure (Noyle and Painter, 2009)

57. “An ecosystem is a natural unit consisting of all plants, animals and micro-organisms (biotic factors) in an area functioning together with all of the physical (abiotic) factors of the environment. Ecosystems can be permanent or temporary. An ecosystem is a unit of interdependent organisms which share the same habitat. Ecosystems usually form a number of food webs…” (Ecosystem, 2009)

58. Geoweb as an Ecosystem Unit: Geoweb Biotic Factors: People Users, Participants Perceptions (top-down vs bottom-up) Change Usability Abiotic Factors: Architectures, standards, formats, specifications, development platforms Relationships Permanent of temporary Interdependence Food webs

59. Future Semantic Web (Web 3.0) Sensor Networks Now: Environmental Modeling, Battlefield surveillance Future: Facilities management (where is that computer in a particular building) (Moreno, 2009)
