THE JSHAPE CAPABILITIES
The web can have the standard functions to display data in the
term oi Internet format. These capabilities are to do the
following process:
Those are only standard capabilities. For the system
development, additional capabilities are added. Those
capabilities are:
Functions
Capabilities
Zoom In
To enlarge the map
Zoom Out
To make the map in smaller view
UnZoom
To set the map in standard size
Clear
To clean the display
Pan
To move the map
Identify
To identify the geocode
Select
To select certain are in the map
Query
To fill the query in SQL forms
Execute
To execute commands and queries
a. Distance calculation
b. Layer identification
c. Area calculation
installation in the same or separate physical locations. Physical
partition means different machines will run different server at a
certain time.
This is the advantage of using this freeware, that we can modify
the facilities easily.
The above capabilities can makes this kinds of web much better
(in geographical terms) than usual webs (that can only display
static images).
THE ARCHITECTURE
Monolithic Model
In the monolithic model, there is only one server which will
handle both textual data (act as textual web server) and spatial
(act as a GIS web server). The model can be illustrated in the
diagram below:
Based on server partition
The meaning of server partition can be logically or physically or
both. Logical partition means separated server software
In this project, because of several limitations, we used this
model as the preliminary model. This model will be improved
in the future.
