Developing a GIS application Developing a GIS application for a mobile client.for a mobile client.

Operational ConceptsOperational Concepts

A mobile client application would utilize A mobile client application would utilize Microsoft MapPoint web services to Microsoft MapPoint web services to determine the places of interest within a determine the places of interest within a certain range of the location of a client. certain range of the location of a client.

A user should be able to access and A user should be able to access and retrieve the driving directions to the retrieve the driving directions to the specified location and the maps of the specified location and the maps of the specified segment of the directions.specified segment of the directions.

A user should be able to update the A user should be able to update the database of the places of interest database of the places of interest

Front End

Server

Application runs on a mobile client such as smart phone or PDA

Front end server provides web services for the application and a sessionID for each client

Database provides a data support for the front end server

Microsoft MapPoint web services acquire the GIS information and convert them into driving directions, maps, etc. to the front end server
