3. INTRODUCTION
Balephi B hydropower
Capacity : 20 MW
Project lies between longitudes 85°45’00” and 85°46’30” and latitudes 27°48’24” and 27°50’48”
Lies on Jalbire, Bataseand Phulpingkot VDCs of Sindhupalchowkdistrict

4. Interactive Web Mapping
Computerized maps that allow users to interact with various aspects of the maps themselves.
Interactive options may include
Zooming in or out on a specified location,
Panning easily between geographic areas,
Have detail information of particular locations by the means of additional info's added to the map objects .
Such maps have become even more detailed and user-friendly, permitting professionals the ability to interact, update, and make changes to the maps in real time.

5. RATIONALE
Static maps provides limited information regarding an object or phenomenon
Tedious job of recording attribute information in the paper regarding every detail
Planning gets ineffective in lack of spatial overview of different features
Details regarding every components at different locations along with different types of interactions on maps aren't available at a single portal
As a result planning activities aren't scientific and effective

6. SCOPE OF WORK
Development of a website of Balephi Hydropower focusing on Interactive Web Mapping with following two major information:
Spatial Information:
Location of Intake structure and dam works, Desilting Basin, Flushing System, Headrace Tunnel, Surge tank, Powerhouse and its inner components, Penstock, Access Roads, Turbine and all other natural and man-made structures.
Attribute Information:
Attributes of above mentioned elements of Hydropower

7. OBJECTIVES
The main objective of this project is to prepare a web map of Balephi hydropower with following features:
An ‘easy to handle’ data updating interface which would actually update the core database
A server connection to the database
A map viewer which would display the database elements (addressing all the recent updates)
Different components of the hydropower along with their specific details
Other important aspects like Social and Environmental impacts of the project

8. RESOURCES USED
Geoserver:An source software server written in Java that allows users to share and edit geospatial data.
PostgreSQL(postGIS):PostgreSQLis a powerful, open source object- relational database system.
Openlayers: Pure JavaScript library for displaying map data in most modern web browsers, with no server-side dependencies.
Apache(http server):Apache is an open-source software. The Apache HTTP Server is a web server software program.

11. MAJOR ADVANTAGES
Visiting the project site each and every time to obtain information on the works progress can now be done sitting in-front of your computers
Researchers can now download and upload the information regarding the natural environment around the hydropower plant
Different levels of security according to the user groups has increased the reliability of the system

12. LIMITATIONS
Requires good internet connection. Offline data loading is not available for data layers.
Data loading is comparatively slower in our website while loading large amount of data
Data regarding Social and Environmental factors are still lacking in the website.
Present website can only be accessed through local server

13. RECOMMENDATIONS
Other modern libraries like leaflets can be used for visually attractive maps
GeoJSON data formats can to be used for effective and fast data loading
Real time data from sensors can also be incorporated
Map prepared in this way can be hosted through the map server installed at KU
It will help any individual to easily visualize the details of the hydropower components and ongoing works

14. CONCLUSION
Aweb based visualization of all the details of a hydropower plant has been finally created.
Interactive web maps should be prioritized in the website of Hydropower companies because they explains a lot about every single components of project
A trend of utilizing the power of geospatial knowledge and World Wide Webto disseminate the useful information of a project site through interactive web maps is already initiated.
