Choice of Operating System 
The Schedule 
92 
Basically the choice of operating system in this kind of system 
is depend on the GIS Map Server platform and Web Server 
Platform. Both UNIX and Windows NT have its own 
advantages and disadvantages. In this project implementation, 
the operating system used here is Windows NT 4.0 Server. This 
is because the web server is on Windows NT. hi this system, 
there is no GIS Map Server, since this GIS Internet System is 
very simple, and according to several constraints. 
To develop this system, assumed that the map data is in the 
digital format already, it takes 60 days. The schedule is 
including the data collection, interface design, web 
programming (in MS Frontpage ’98), Java Script and Java Class 
Programming (Using Java Development Kit from SUN 
Microsystems) to improve the JShape tool, internet publishing 
and training to the users and administrators. 
The implementation schedule for this system is as follows.

Further Development 
For further development, this system should be enhanced by 
adding: 
1. Better spatial database access by using spatial data 
warehousing 
2. Better and more communicative user interface by using 
Java Class, and the latest internet web-design technology 
3. Better Internet GIS shell. This can be done both by 
improving the existing JShape Java Class, or using web- 
application that can be developed using several 
programming languages such as Oracle, MS Visual Basic, 
Powerbuilder, etc, using GIS Active X’s such as Maplnfo 
MapX, and ESRI MapObject. 
Alternative System 
As an alternative of this system, the map server-based GIS is the 
best choice. This technology uses Internet Map Server kind 
software (such as Maplnfo MapXtreme, ESRI IMS, Sicad IMS, 
and Autodesk Mapguide). The application for this kind of 
system will be developed under web-based application 
development environment (such as MS Visual Interdev, 
HAHTSite, and ColdFusion) using GIS Client object (such as 
Maplnfo MapX, ESRI MapObject, etc)

The diagram shows us a slightly different system than the 
system we proposed. Instead of having applet and doing the 
local processing, the system described in the diagram above 
using client-server processing and server side application-based 
processing.
