Life Cycle Objectives
CSE 403 Project:
Developing a GIS application
for a mobile client.
Operational Concepts



A mobile client application would utilize
Microsoft MapPoint web services to
determine the places of interest within a
certain range of the location of a client.
A user should be able to access and
retrieve the driving directions to the
specified location and the maps of the
specified segment of the directions.
A user should be able to update the
database of the places of interest
System Requirements




Get request from a user, create a session, and invoke the
appropriate web services
Retrieve the information from MapPoint and transfer it to
the client application
Client app should display the results in a dynamic format so
user would be able to call these results again for more
options
Sample usage:
Traveling range and the current location ->
List of places of interest with feedback and rating ->
Driving directions to the specified location ->
Map of an individual segment from the driving directions
Coordinates and name of the place + the feedback/rating ->
Update the database according to the provided information
System Architecture
 Application runs on a
mobile client such as
smart phone or PDA
DB
 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

Software architecture


Create a .Net application using C# and Microsoft
SQL server
Well defined web services of 2 categories:
• Utility services


Retrieve information from database
Utilize MS MapPoint web services
•
•
•
•
Calculate a route according to coordinates
Retrieve a map with starting point and an end point
Retrieve driving directions
Retrieve map for each segment of directions
• Client-server services



Establish a session
Retrieve information from a client
Deliver a map, a list of directions, or a list of locations to
the client
Lifecycle Plan

Split the development and design into five categories:
• Mobile client app interface
• Communications between the mobile client and the front end
server
• Database for the places of interest and communication of the
database with the front end server
• Front end server architecture and web services
• Interface between a front end sever and the Microsoft
MapPoint web services



Distribute the requirements between the team members
according to strengths and interests
Produce a pre-release version every week and test all the
parts together
Update system requirements and architecture according to
the feasibility and deadlines
Feasibility

Seems feasible, but a lot of uncertainties
and risks
•


MapPoint services
7 weeks of project time
Technicality
Group coordination (other projects and
classes)
Further discussion with the group has to
be made before deciding the feasibility of
the system given the architecture and the
deadline
