Geographic Information System
GIS is a computer-
based technology to
collect, integrate,
analyze, query, model
and visualize
geographic-oriented
data (like a visual
database)



  Technology, Methodology, Profession, Business
                                                  Bolstad, P. (2008).
Answer Global and Local Questions
 Location
  –   What is at …?
  –   What exists at a particular location?
 Condition
  –   Where is it?
  –   Find location where certain conditions
      are satisfied.
 Trends
  –   What has changed since?
  –   Differences in an area over time.
 Patterns
  –   What spatial patterns exist?
  –   Spatial relationships between
      geographic data.
 Modeling
  –   What if …?
  –   Predict cause and effects of new
      scenarios.




                        Great examples of GIS in action here!

Web GIS Models




                 Fu, P. & Sun, J. (2011).
Web GIS Architecture




                       Fu, P. & Sun, J. (2011).
Application Components
Basemap
– Often cached services pre-created by server
      Road map
      Aerial imagery
Operational layers
– Dynamic data rendered by the browser
      Real time weather
      Disease locations
Tools
–   Find an address
–   Get directions
–   Query or search
Geospatial Web Services
Application components are driven by
geospatial web services
– Web service is a method of communication
– Programming interface that can be accessed
  by other applications
Fu, P. & Sun, J. (2011).
Service Functions
Map services
– Most basic: display, query, identify
Data services
– Edit, serve imagery, synchronize
Analytical services
– Geocode, route, proximity, buffer,
– Geoprocessing – custom analysis models
Service Standards
Open Geospatial Consortium
– WMS (Web Map Service)
– WFS (Web Feature Service)
– WCS (Web Coverage Service )
Other related standards
– KML (Keyhole Markup Language)
– GEORSS
– GML (Geography Markup Language)
REST Services
“With REST, everything is a URL”
– Communication type used between the web
  service and the browser (client)
   Using the ArcGIS Server Rest API to generate a map covering the
   United States, asking the return to be a JPEG of 800 pixels by 500
   pixels, the request is the following:

   http://server.arcgisonline.com/ArcGIS/rest/services/ESRI_ShadedReli
   ef_World_2D/MapServer/export?
             bbox=-183.33, 15.20, -9.53, 74.08
             &size=800, 500
             &format=jpg
             &dpi=96
             &f=image
                                                                        Fu, P. & Sun, J. (2011).
The Mashup
Bringing it all together
– Integrate diverse resources to create an
  application
Use browser side API to represent web
services and handle user interaction
– API for JavaScript
– API for Flex
– API for Silverlight
ArcGIS Viewer for Flex

  • 13. Service Functions Map services – Most basic: display, query, identify Data services – Edit, serve imagery, synchronize Analytical services – Geocode, route, proximity, buffer, – Geoprocessing – custom analysis models
  • 14. Service Standards Open Geospatial Consortium – WMS (Web Map Service) – WFS (Web Feature Service) – WCS (Web Coverage Service ) Other related standards – KML (Keyhole Markup Language) – GEORSS – GML (Geography Markup Language)
  • 15. REST Services “With REST, everything is a URL” – Communication type used between the web service and the browser (client) Using the ArcGIS Server Rest API to generate a map covering the United States, asking the return to be a JPEG of 800 pixels by 500 pixels, the request is the following: http://server.arcgisonline.com/ArcGIS/rest/services/ESRI_ShadedReli ef_World_2D/MapServer/export? bbox=-183.33, 15.20, -9.53, 74.08 &size=800, 500 &format=jpg &dpi=96 &f=image Fu, P. & Sun, J. (2011).
  • 16. The Mashup Bringing it all together – Integrate diverse resources to create an application Use browser side API to represent web services and handle user interaction – API for JavaScript – API for Flex – API for Silverlight
