Open GIS GIS is moving from Desktop system to Distributed system → OpenGIS concept → Where 2.0 Open Geospatial Consortium (OGC) http://www.opengeospatial.org Develop specifications to increase the interoperability of geospatial data and geoprocessing software components 8

Advantages of OpenGIS Cost cutting Platform independent Comply with OGC standards which were accepted by wide- range of governments, organizations, companies Reuse existing resources of data Expandability, easy customization and integration Solve integration, interoperability issue of GIS systems in the real world 10

What is mobile? Mobile is the ability to be on the move. Mobile features: Ubiquity (primary advantage) Reachability Localization Personalization Dissemination 11

The wand Physical Virtual 12

What is LBS? LBS = Location-based Services “A wireless-IP service that uses geographic information to serve a mobile user. Any application service that exploits the position of a mobile terminal.” [OGC, 2005] 13

What is LBS? LBS as an intersection of three technologies GIS/Spatial Database Web Mobile GIS GIS LBS Mobile Internet ICT*/mobile Internet devices 14 ICT* - Information and Telecommunication Technologies

LBS usage 15

LBS methods 16

Mobile GIS components 17

Challenge? Mobile device constraint LBS is still not a mass market technology Very little GPS enabled phone Difficult to access to other technologies (CellId,…) User generated content needs critical mass to be interesting It’s not easy to create content on mobile Device fragmentation Data prices Privacy etc. 18

What is Java ME? Java ME = Java Micro Edition It just means Java for small devices Borned in 1999 Java ME is not A specific set of software A specific set of APIs Java ME is divided in configurations and profiles These provide specific information for a group of related devices 19

Why Java ME? ● Yahoo! Go chose Java ME ● Gmail Mobile, Google Maps Mobile chose Java ME ● ..and Microsoft chose Java ME for Windows Live Mobile 20
