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.
