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, Batase and Phulpingkot VDCs of Sindhupalchowk district

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.

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

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

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

RESOURCES USED

Geoserver: An source software server written in Java that allows users to

share and edit geospatial data.

PostgreSQL(postGIS):PostgreSQL is 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.

METHODOLOGY

Data Collection

Data Preparation

Web Mapping

System

Architecture

OUTPUTS

Final output of this project isn’t just an interactive map but it’s a complete website of

Balephi Hydro

Major feature of website:

Admin and general User Privilege : Provides different level of access

according to the user type. eg: Admins can edit the data

Customized Pop-Ups: Details regarding every components of the hydropower

can be obtained interactively

Zooming ,Panning ,Overview, Layer Switchers etc. has added more level of

interaction

Download facility where users can download the files in different formats like

CSV,KML,PDF and shp file formats

Attractive CSS to increase the beauty of the website

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

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

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

CONCLUSION

A web 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

Web to disseminate the useful information of a project site through

interactive web maps is already initiated.
