INTRODUCTION
The Internet is a Virtual trove of information. Any kind of
information on any topic under the Sun is available on the
Internet.
The World Wide Web (W3).
Internet GIS is a research tool that facilitate to access,
process and dissemination of geographic information and
spatial analysis knowledge
WEB GIS
With WebGIS, users do not need to purchase and install
expensive GIS software in order to access and work with
maps and databases.
Also, users do not need to become experts in sophisticated
GIS applications, since the functionality is made available
through a regular web browser and an integrated Viewer
with a simple, user-friendly interface.
The focus of the paper is to demonstrate how WEBGIS
technology can be employed for spatial data collection.
CLIENT /SERVER
Web GIS is a client server concept.
We are using the Internet Map Server and Web Server to host
the designed web site.
ArcIMS is a solution for delivering dynamic maps and GIS data
and services via the Web.
It provides a highly scalable framework for GIS Web publishing.
Using ArcIMS, city and local governments, businesses, and
other organizations worldwide share geospatial information both
internally and to the public.
CLIENT SERVER
WEB SERVER
A web server can be referred to as either the hardware (the computer) or
the software (the computer application) that helps to deliver content that
can be accessed through the internet.
Most people think a web server is just the hardware computer, but a web
server is also referred to as the software computer application that is
installed in the hardware computer.
The most common use of web servers are to host websites but there are
other uses like data storage or for running enterprise applications.
There are also different ways to request content from a web server. The
most common request is the Hypertext Transfer Protocol (HTTP), but there
are also other requests like the Internet Message Access Protocol (IMAP)
or the File Transfer Protocol (FTP).

METHODOLOGY
PREPARATION OF BASIC SPATIAL DATA
The LULC map of Tuticorin for the year 2003 was
prepared using LISS III satellite data by using
supervised classification method for the purpose
of developing WEB GIS.
The Tuticorin topomaps (1969) were digitized and
the extent of the Settlement, saltpan, wasteland,
Agricultural land and Water bodies were extracted
using ArcGIS 9.2 software
ARCIMS
ArcIMS is used in developing the GIS web-base application as
it is an Internet Map Server software which provides the
components required for web development such as authoring,
designing, publishing and administering Internet mapping
application. It allows web clients, map server, data server and
Web Server to communicate between one another. Through
ArcIMS, developers are able to build the web-based GIS faster
and manage MapService over the internet.

A WEB SITE
ARC IMS - AUTHOR
ArcIMS Author to
create a map for our
Web site by performing
such tasks as adding
data layers, setting
layer symbology and
creating stored
queries.
Author always saves
your map content in a
configuration file with
the .axl file extension.
ADMINISTRATOR
The Administrator can create, start, stop, and
remove services. Administrator can set and
change service properties, such as the Virtual
Server assignment. Administrator also lets
you work with servers (map server, image
server and feature server).
DESIGNER
ArcIMS Designer is an application
that guides you through the viewer
design process.
One can design the web page using
HTML or JAVA.
In the java, designer can create a
web page using java standard or java
custom tool sets.
Most of the tools do not appear if you
choose the Java Standard.
In the present study, we design the
website to display the layers such as
Settlement, Saltpan, Agricultural,
Waste land and Water bodies for the
year 1969 and 2003 using HTML

LAND-USE AND LAND-COVER
CHANGE (LULCC)
 Humans have been modifying the surface of the earth rapidly for
their needs such as food, settler and other essentials.
 These changes encompass the greatest environmental concerns of
human populations today, including climate change, biodiversity
loss and the pollution of water, soils and air.
 Monitoring and mediating the negative consequences of LULCC
while sustaining the production of essential resources has therefore
become a major priority of researchers and policymakers around
the world.

Keeping these perspectives an, attempt has been made to
analysis the land use and land cover changes that have taken
place from 1969 to 2003

QUERY TOOL
Query tool is one of the best option in the web based LIST, The Query is
written using SQL (structured query language). We can use Query with
logic algorithm and basic arithmetic functions. The query function is
used to select the particular soil type as shown

BUFFER TOOL
Buffer Tool selects the features of one layer that are within the specified
buffer distance of selected features of another layer. The buffer zone
created for the particular Road map
MEASURE TOOL
Suppose if the user wants to measure the distance between two
points or a path way, Measure Tool is used

The overlaying operation of change detection analyze is very essential to
determine what is exactly changing to what land use class changing to
other. This information will be a vital tool in management decision

ANALYSIS
Attempts were made to capture as accurate as possible land use and
land cover as they change through time.
Tuticorin has witnessed remarkable expansion, growth and
development activities such as urban sprawl development and
conversion of land into settlement, Industrial area and saltpan.
Mostly the contributors for the development are identified as waste land.
During the development the salt pans and some settlement near the
cost, sand dunes and palaeo strandlines were demolished.
These above said structures are storage tanks of freshwater in coastal
aquifers. So the demolition of these structures leads to cause strain in
coastal aquifer systems.
Salt Pan
CONCLUSION
The WEB GIS is found to be very useful in monitoring
the urban growth of a thickly populated and rapidly
increasing city like Tuticorin.
WEB GIS acts as an important tools for the developers
and planners to extract Spatial data of their interest.
