Introduction
The most valuable asset an enterprise owns is its information. The challenge is to make that information quickly and easily available to users so that they can use for productive works.

In earlier days, if a person wanted to get information about an urban area, he was required to approach different authorities and the information was available on different scale with different accuracy. Combining this information was a difficult task. Each department carry out their own mapping work independent of other department thereby different departments duplicates much of work. This problem may be overcomes if there is a centralized information system for an area. This can effectively be done using GIS, which relate the spatial and non-spatial database. For providing the spatial and non-spatial information on Internet the web GIS is used. Web GIS allows user to create Web sites or web pages that put control over the creation and display of GIS data over the net.

GeoMedia Web Map is a Web-based map visualization and analysis tool that provides real-time links to GIS data warehouses. User can query a database and see information described in a map – or click on a map feature or area and see selected database information about that particular map feature. GeoMedia Web Map enables user to access and analyze data anywhere, anytime. It enables users to access data in its native format – without translation or conversion – and performs queries on live data to get the answers they need. User is able to pan, zoom, area-measure, location, queries and displaying various features.

Objective of Present Study
The main objective of report is to develop a web based master plan of IIT Roorkee campus in graphical form. User can query a database and see information about buildings, apartments, hostels, canteens, buildings to be demolished, proposed buildings, proposed roads, exiting roads, labels, and departments using GeoMedia Web Map.

Master plan of IIT-Roorkee Campus
The University of Roorkee, the fountainhead of technical education in India has been transformed into Indian Institute of Technology Roorkee recently. Being the pioneering institute in technical education in the whole of Asia, its campus has a glorious heritage developed over a long period of 155 years. This phase of transformation from the old University of Roorkee to Indian Institute of Technology, Roorkee in its all aspects is very crucial from the point of view of its further development. This has provided a golden opportunity to prepare a comprehensive Master Plan document to ensure a well-balanced sustainable future growth of the campus.

Present Status of the Campus:
Table- 1 shows the present population of the campus area and table -2 gives the area in acre of different utilization.

Table 1: Population status of the campus. [1]

Faculty sanctioned	628 nos.
Non teaching ‘A' 'B' 'C' 'D' in position	1255 nos.
Sanctioned	1438 nos.
Total population	12497
Gross density	35 persons or 7 families/acre
Net density (exclusive of students)	21 families/acre

Table 2: Area distribution status of the campus. [2]

Area distribution
Housing	100 acres	30%
Hostels	50 acres	15%
Academics	50 acres	15%
Central facilities	20 acres	5%
Roads	60 acres	15%
Open spaces	78.5 acres	20%

Present Challenges:
In the preparation of the Master Plan document following challenges / issues have been identified which will have to be addressed in an explicit manner for achieving the overall vision of the Master Plan:

1. Most of the single or double storied houses occupies large open areas with very low-density i.e. approximately 30 persons per acre. Also, many buildings are very old and require huge maintenance cost. So the densification of the campus is a challenge.
2. Due to the major flexibility brought about in the curriculum by the introduction of the institute's and the departmental electives, there is an immediate need to build number of sizeable lecture hall complex and increase the number of smaller lecture classrooms as per the individual needs of the departments.
3. The Main Building, a great heritage edifice of the campus, does not have a dignified and respectable access. At present, it is approached mainly from behind.
4. With the increase in the number of vehicles on the campus, like cars and scooters, it has almost become a challenge to provide proper parking lots for the main building and other departments also.
5. The unique feature of this campus due to its glorious development of 155 years is its well-recognized heritage buildings. It will be a stupendous task for the institute to restore them in their original character and also to preserve them for posterity.
6. Due to the long period of growth of the campus, much of its drainage system, being an open drainage system, has become obsolete. Moreover, the increasing burden of waste disposal is another major challenge facing the institution.

Objective of Master Plan
The following main objectives have to be fulfilled to transform the Master Plan into reality.

1. To ensure overall security of the campus.
2. To create safe, convenient, academically live environment.
3. To increase the density of housing / dwelling units /acre.
4. To cater the immediate needs and have adequate provision for future needs.
5. To maintain harmony between its glorious heritage edifices and new development.
6. To achieve appropriate balance between spatial allocations of housing, academic, physical infrastructure areas.
7. To rejuvenate its eco-friendly, arcological built environment.
8. To prepare overall conceptual framework to ensure quality of life in the present time and of future development as well.

Conclusion
The following Conclusions are drawn from the present work:

Fast and Easy Access: One can access and use geographic data to obtain frequently requested information from sources such as department, hostel, utilities, Apartments, main building, sports facilities customer service, public access along with geographical locations. People don’t have to come to the data – the data comes to them. Since the map is a live view of the geographical information, users always view current information. Build on your current assets.

Online Mapping: user can zoom in; zoom out, area measure, location, pan, vector map, refresh map on Internet.

Online Query: Our system provides the functions of query from map to attribute and also from attribute to the map. Query about different important buildings, demolish phases of buildings and the proposed buildings in campus area according to campus need. These values will greatly help user making his decision.

Online Analysis: Each feature in the map is linked to its attribute information, enabling the user to see a report about that feature.

The present work is a Client-side Internet GIS application, which requires Microsoft Internet Explorer 5.0 or later.
