corresponding Coordinate Reference System (CRS), and zoom and pan the result map, 

etc. It is not easy to let those interfaces run without mistakes in one clear workflow. 

1.3  Motivation 

The  reason  to  choose  this  domain  is  that  this  is  an  upcoming  field  and  has  a  lot  of 

scope  from  a  research  point  of  view.  Further,  the  client  designing  on  the  mobile 

devices seems  interesting and challenging, and till  now most of all the  WMS clients 

for  the  mobile  phone  are  based  on  raster  image  format,  not  vector  image  format, 

which was also a motivation to choose this as research area.   

Moreover  the  coming  times  are  going  to  large scale  development  of  commercial 

applications  based  on  location  based  services.  Such  application  can  be  extended  in 

many aspects, such as navigation, mobile service, library service and so on. 

1.4  Methodology 

According to the objectives, the corresponding methodology is established. 

1.

Pre Analysis

:  The  current  situation  will  be  analyzed,  including  the  study  of 

the theory  part of  J2ME  and  SVGT,  how to  parse  XML  document  in  mobile 

devices etc. 

2.    Selection  of  scenario

:  The  testing  system  will  be  selected,  including  the 

testing software and servers. Several Web Map servers which produce SVGT 

(SVG) map or raster image will be as the testing server. 

3.

Design the code structure and user interface

:

In this step, the code structure 

and user interface should be designed as one clear workflow in advance. 

4.

Debug  the  codes

:  The  codes  will  be  debugged  carefully  and  using  some 

virtual simulator to test it.

5.

Test of client

: The client will be tested both on mobile phone and on simulator, 

trying to connect different WMS to check its performance.
