IntroductionLocation-Based Services (LBS) Spatial Data Warehouse: Dataset containing features from a

defined area localization and Guidance:

Where is the user, where does he want to go?

User Interface: How the information is delivered to the user

3

IntroductionGeographic information system (GIS)WebGISIntegration the relative of Geographic

information and database Storing, analyzing, updating and displaying

geographically referenced information

4

MotivationSpatial information share

Integration of information space and physical space

Interactive relationship between human and computer.
