• Conclusion
– Value of the Enterprise Architecture
MilitaryINSTALLATIONS Requirements
• Deliver a user friendly GUI with Google Maps like functionality
Pan/Zoom, ToolTips, Interactive
• GeoCode existing address of base level services as defined by
DoDITC
• Enable geospatial searches for base level services
• Easy of Use
– Hide traditional GIS complexity from end users
• Display and query “Nearby” Points of Interest Data
• Route between base level services and POI’s
• Extend and use existing Oracle DB platform
 Storage and analysis of geospatial data in Oracle Spatial
 Implementing the Oracle LBS API for routing

Support service personnel on travel via mobile devices
Application Components

Mobile Application Requirements
• Must use the existing Enterprise
Infrastructure
• All functionality must be available to the
mobile device
–
–
–
–
Map rendering and navigation including pan/zoom
Routing
POI searches
External services – weather/image
• MUST BE INTUATIVE AND EASY TO USE
Development Considerations
• Limitations of Mobile Devices
–
–
–
–
–
Support of JavaScript
Navigation tools
Interactive Screens
No cursor
Limitation of various mobile browsers
– Blackberry
– Windows CE / Mobile Internet Explorer
Development Approach
• Mobile Specific Path
– http://militaryinstallations.dod.mil/mobile/
• WURFL – Exact match / Loose match
– Only trust exact match
– Screen size
• Windows Headers
– Screen size
• BlackBerry User Agent
• Automatic redirect if sure
Development Approach (Cont.)
• SiteMesh
– Page headers and overall layout differences
• Struts
– Model View Controller
– Same code for different presentation
• JSP Includes
– Majority of HTML same for mobile/desktop
• CSS / HTML
– HTML tags indicate content type
– CSS indicates content style
Installation Location
Mapping of Services
Locating POI’s
Routing
Supported Mobile Devices
HP iPAQ
Blackberry
Palm Treo
Conclusion
Advantages of the Enterprise Architecture
•
•
•
•
Single source of data
Single source of application code
Web application code mostly reusable
Server side processing
– No need for any application code on the mobile device
• Ability to integrate web services at the middel tier
– OGC WMS Image Services
– XML Weather Services
• Leverage Enterprise Security Model if required
CHEAP AND FAST TO BUILD THE MOBILE
