• 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

• Integrated through the MilitaryHOMEFRONT Oracle Portal– Standard web browser application

• Oracle 10g Database and Application Server• Oracle Spatial with LBS API• eSpatial’s iSMART development framework• NAVTEQ Data• Real-time Custom Weather services via XML• Application available to industry standard

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

BlackberryPalm Treo

HP iPAQ

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
