CHAPTER: 1 INTRODUCTION AND BACKGROUND
1.1. Backgroundand Introduction
1.1.1 Introduction of Project
As a part of Author’s Bachelor in B.Sc.CS.IT author did a 3- month internship at GIS
Company. Geographic Information Systems (GIS) is “a computer-based system to aid in
the collection, maintenance, storage, analysis, output, and distribution of spatial data and
information”. It is an extremely powerful tool that is a key component to do development
work in different places without affecting other resources. With the Genesis GIS Group,
the provided project Arsenic Information Management System had five modules and
task assigned for author was on web GIS. Task was given to create tools for research
projects, hotspot map, and Webpages, and used GIS and statistics to analyze provided
geospatial data and answer research questions.
For creating tools at first OSM map is used and to link different task with each other
different webpages are created. Then load the provided data of different boundaries,
districts and electrical poles, lines, transmitters into different webpages which contain OSM
map. Some normal data that are loaded which are in the computer but those data cannot be
further edit so have to change those data into that form of data which could be edited. So
the data are further converted into GeoJSON file which could be edited as necessary.
Further some libraries, queries were added to create different geometrical shapes. And then
write some functions to count the number of points inside it and then set the range value
and show the points according to the range value provided by the user. Three layers of
webpages are there one for count points, another for lines and last one for hotspot map
which contain all the data of previous two webpages.
1.1.2 Scope of the project
 User can easily get the information about the arsenic level
 Hotspot map helps to find the location of the given data in the system easily
 Clicking in point provide the detail of the point.
1.1.3 Limitation of project
 Requires enormous data which take long period of time to load.
 Error on loading data into the system

The required information, detail, data are already collected by the staff of the company so
the necessary data for the task are provided by the company which includes Analysis data,
Boundaries data and Arsenic data. The given data consist of point, line and polygon with
detail information.
2.2. System Requirements
2.2.1 Functional Requirement
Functional Requirement are statements of services that system should provide. It describes
what the system should do. They are helpful to describe the system function in details. Here
are some of the functional requirement for the system used by the users. The system
includes different function which should be performed within the system environment.
Use Case:
The use case below shows the working pattern of the user in the system. The user first have
to choose the file which are given in the selection button when the loaded data is showed
in the interface then the user have to draw polygon or circle. When drawing end then the
function will perform task and then the user can set the range of the give data and finally
submit it and see the result. In second use case diagram the user has to choose the file and
when click on submit button the choose file is showed in interface. Last use case diagram
contains two type of data selection one for point data and another for line data and when
the user choose the file them the respective file is showed into the interface.

2.2.2 Non-functional Requirement
 Efficiency :
In our system client can view the points according to the selected points and with
different level of arsenic level.
 Reliability:
The system will provide a reliable environment to both client and company. The
client requirement will be fulfilled without any errors.
 Usability:
The system is designed for user friendly environment and ease of use.
 User Interface:
The system maintains an easy to use interface across all functionality and for all
users. The client’s user interface is compatible with all commonly used devices.
2.3. Process Model of the System
The process model shows the flow chart which describe how the user can work. First the
user has to select in which part the user want to work. And then if the user chooses point
the user have to select respective file and draw the geometric figure and get the result and
if user select line then just select file. If user choose hotspot map then user get two options
one for showing single data output and another is multi data output (Geraldo, 2017).

Chapter: 3 System Design
3.1. ProcessDesign
Process design describe about the procedure of the system. The figure describe the
procedure and links of component in the system. At first index page will be loaded and the
first page will be loaded with other two pages. Index.htm is linked with mouselocation.js,
main.js and load coordinates and map layers respectively. Main.js call functions to draw
geometric figure and the server to load files (Thomasg77, 2015). To load file from server
the user have to start tomcat server at first. Some files are stored in the computer so some
file will be loaded from computer and after processing the output will be showed in UI.

24. 12
CHAPTER: 4 IMPLEMENTATION
4.1. Front End Tools
 Html: HTML (Hyper Text Markup Language) is used to create the Design the web
pages for the system. It is used to create the user interface in the system. Web
browsers can read HTML files and render them into visible or audible web pages.
HTML describes the structure of a website semantically. Different HTML Tags are
used in our web application version.
 CSS: CSS (Cascading Style Sheets) is used in this system to add designs, colors,
etc. CSS is used for describing the presentation of a document written in a markup
language. Changes to the graphic design of a documents can be applied quickly and
easily by editing a few lines in the CSS file they use, rather than by changing
markup in the documents.
 GEOJSON: GeoJSON is a format for encoding a variety of geographic data
structures. GeoJSON file supports point, line, polygon, multipoint etc. which are
used in the project as the data.
 JavaScript: JavaScript is high level language. It is used to write functions and use
GeoJSON file into the map.
4.2. DocumentationTools
 Microsoft Word: Microsoft Word or MS-WORD (often called Word) is a graphical
word processing program that users can type with. It is made by the computer
company Microsoft. In our project Microsoft word is used for documentation
process.
 Microsoft Visio: Microsoft Visio is used for diagramming and vector graphics
application. In our project it is used to create diagrams in a simple and convenient
way this tool is used.
4.3. GeoServer
GeoServer is a OGC compliant implementation of a number of open standards such as Web
Feature Service (WFS), Web Map Service (WMS), and Web Coverage Service
(WCS).Additional formats and publication options are available including Web Map Tile
Service (WMTS) and extensions for Catalogue Service (CSW) and Web Processing Service

25. 13
(WPS). Geoserver runs at http://localhost:8080/geoserver. It is designed to publish data
from any major spatial data source using open standards. Geoserver has evolved to become
an easy method of connecting existing information to Virtual Globes such as Google Maps
and Bing Maps.
GeoServer allows us to display the spatial information to the world. Implementing the Web
Map Service (WMS) standard, GeoServer can create maps in a variety of output formats.
Open Layers, a free mapping library, is integrated into GeoServer, making map generation
quick and easy. GeoServer is built on Geotools, an open source Java GIS toolkit.

26. 14
CHAPTER: 5 TESTING
Testing is a process of executing a program or application with the intent of finding the
software bugs. It can also be stated as the process of validating and verifying that a software
program or application or product meets the business and technical requirements that
guided its design and development.
5.1 Manual Testing
Manual testing is a testing process that is carried out manually in order to find defects
without the usage of tools or automation scripting. It is the process of manually testing
software for defects. Functionality of this application is manually tested to ensure the
correctness. It is the most primitive of all testing types and helps find bugs in the software
system.
Since the given task are simple and no need to test using different testing methodologies
and there are no such functionalities which have to be tested using different methodologies
so the given task is tested using manual testing by the user. Some test case are:

CHAPTER: 6 CONCLUSION
6.1 Conclusion
During the internship phase of building a career in GIS, I have learn the different types of
software and hardware technology available in the field. Along with learning, I was
exposed to the different types of Internet languages, beginning with HTML; which is the
ground work of all web languages, and leading into others, such as, PHP, JavaScript. The
learning curve of an intern depends on what is offered at each internship job, this is why
students have the opportunity to work in several internship positions. The experience is
different in each job position can vary from each employer.
From this report, Author have tried to include overall findings of her internship period and
have included the knowledge that she gained as far as possible. She used different concepts
and tools related to Web Development such as Java, CSS,Open Layers, JQuery, AJAX etc.
which she have learned during her educational period and also get directions on how to use
them in real world creating personal as well as commercial websites. Finally, she has
become successful to bridge upon the gap between the theoretical knowledge that she have
and the real world implementation of that knowledge.
6.2 Future Enhancement
There are certain improvement that can be do in future. Following are some of them:
 User GeoJSON file to work on line data
 Improve the UI of hotspot map
 Include more options in hotspot map
6.3 Lesson learnt
Working as an intern in Genesis Consultancy (P) Ltd has been a great experience in
learning new things and gaining practical knowledge about the working of Software
Company. This internship period will surely be helpful in the future to start a career in GIS.
During the intern period she came to realize that theory knowledge is incomplete without
practical knowledge. But to work in practical environment the theory knowledge is very
important. The intern period helped her to build her confidence and strong determination
towards professional life. Some of the lessons learnt during internship period are as follows:
 Work in group and make quality group decision.
 Working under pressure.

28. 16
 Importance of coordination and cooperation in the work environment.
 Understanding the difference between theoretical knowledge and practical world.
