4. 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).

5. 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!

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

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

10. 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

11. 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

12. Fu, P. & Sun, J. (2011).

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

17. ArcGIS Viewer for Flex

20. Demo: site process

21. Start right now!
