LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Odoo provides an option for creating a module by using a single line command. By using this command the user can make a whole structure of a module. It is very easy for a beginner to make a module. There is no need to make each file manually. This slide will show how to create a module using the scaffold method.
2. Background
The introduction to Information Systems is designed for non technology oriented
Managers to understand the implication of Information Technology and Information
Systems in their organization so that they equip themselves with the necessary
knowhow to cope with both embracing technology in their department and also get
ready for the next wave of Information Systems – Artificial Intelligence and Machine
Learning which is getting deeply embedded in the day to day Information Systems
in the organization
This is also useful for Management Students ( PGDM and MBA) who don’t have
background in Technology to make their foundation for both Technology related
courses in Management and get them ready for the new technology job market
The style of writing this book is deliberately made in bullet point concepts approach
so that students can understand the concepts with one reading .

• Topic :
• Data
• Information
• Knowledge
• Wisdom
• DIKW Model Pyramid
• Corporate Pyramid
• Information Systems Pyramid
• Decision Making Types Pyramid
4. Understanding
Data
• 230975 is Data
• 23/09/75 is Data – It could be
anyone’s DOB
• DOB 23/09/76 Suresh – Data –
Could be any Suresh in the world
• DOB 23/09/76 Suresh s/o of
Ramesh – Data –could be any
Suresh s/o of Ramesh
• DOB 23/09/76 Suresh s/o Ramesh
R/o of …….is Information as now
there is “Context “ to Data
5. What is
Data
• Data is collection of Raw facts
and Figures
• Data can be represented by
alphabets, numbers , special
characters and images
• A-Z , a-z , 0-9 , @#$%&*<>>,.”;’
• Taken in isolation “Data “ conveys
no meaning or context
6. Information
• “Processed” Data is “Information”
• There can be multiple Processes on
data to get the Information
• Data + Context = Information
7. Information &
Knowledge
• 120/80 ,130/90, 140/100 , 150 /110
is Data
• BP I 120/80 ,130/90, 140/100 , 150
/110 is still Data
• BP I Date I Time I Name I 120/80
,130/90, 140/100 , 150 /110 is
“Information”
• BP I Date I Time I Name I 120/80
,130/90, 140/100 , 150 /110 I Low
,Average ,High – is Knowledge
• Information + Rules = Knowledge
8. Knowledge &
Wisdom
• In the previous examples of BP
Readings , here is decision of 3
doctors
• Decision of Doctor 1 on BP Reading
–Take Rest
• Decision of Doctor 2 on BP Reading
–Take Medicines
• Decision of Doctor 3 on BP Reading
– Get Hospitalized
• Knowledge + Experience = Wisdom
9. DIKW
Application
• Data is considered the new “Oil”
but is “useless” or is like “Crude oil”
(What)
• Insights and Information processed
from Data is “Refined Oil” (Why )
• Where to use the oil is Knowledge
(What's happening)
• Whether to use the oil , conserve ,
sell is Wisdom ( Prediction /Future
Forecast)
15. What is
System
• Definition of “System” - A system is
a set of rules, an arrangement of
things, or a group of related things
that work toward a common goal
• System is a general set of parts,
steps, or components that are
connected to form a more complex
whole.
16. Five Components
of IS –Information
System
• Hardware – Physical devices –
computers , tablets , mobile phones
• Software – Tells the hardware what
to do
• Data –Information manipulated by
Software
• People –Users , Programmers
,Analysts , IT Dep't
• Process- steps to accomplish a
goal
• Telecommunications /Networking

22. Chapter 2 –
Types of
Information
Systems
• Information Systems can be broadly
divided into following four categories:
• TPS – Transaction Processing
System
• MIS – Management Information
System
• DSS – Decision Support System
• EIS – Executive Information System
23. Types of
Business
Information
Systems
• Operations Support – Provided by
TPS
• Management Support – Provided
by MIS , DSS & EIS
• Other Business Support Systems
• - GDSS ( Group Decision Support
System )- Communications
(Chat/Mail ) , Conferencing (
Audio/Video Conferencing ) and
Collaboration ( Workflow)
• - Knowledge Management
• -Expert Systems
24. Types of Decisions
• Structured – Inventory Re order Decision
• Semi Structured – Which product lines to add
in next 1 year
• Structured – Which business to be in next 5
years
25. Transaction Processing System (TPS)
• Captures daily transactions like POS (Point of
Sale ) data in Store
• Helps in Operational Level of Management (
lower Management)
• Online (POS) or Batch Processing
• Pre defined transactions
• No decision making
• Structured problems
• Follows ACID Mode
26. ACID Principle of TPS
• All TPS model follow ACID Principle
• A – Atomicity – Transaction is Full or None
• C – Consistency – All transactions within
defined boundary ex ATM limit of 10K cash
withdraw per transaction
• I – Integrity – All Credits and Debits will be
done simultaneously
• D- Durability – Maintain Log Reports of who
used the system , when
27. TPS Classifier -ACID Test for TPS
• A – Atomicity- TPS is complete in full or not
• C-Consistency- set of operating rules and
constraints of Database Mgmt.
• I – Isolation – Each TPS is different even if they
are at same time
• D –Durability – TPS once done cannot be
undone
28. • There are 5 Stages in Transaction Processing
System
• The next slide shows the graphical layout of 5
stages of TPS
30. Payroll System as TPS
Employee data
Payroll
Simple Calculation
D/B
Name
Address
Salary
DOJ
Tax
Payroll
System MIS Report
Employee Paycheck
(Pre defined output)
Online Queries
(Predefined)
Employee earning > 2 lac/m-will come from MIS not TPS
31. Management Information System
(MIS)
• Captures data from TPS
• Summarizes TPS Data
• Provides “Organization Performance Reports”
• Mostly Structured –Pre Defined decision
making
• Little Analytics
• Example : Grade Sheet of Class Term Result is
MIS (Performance of Class)
32. 4 Types of MIS Reports
1. Periodic and Scheduled Reports – provided on
regular basis – daily /weekly/fortnightly/monthly
ex Sales Reports ,Production & Inventory Reports
2. Exceptional Reports – Only in exceptional
conditions , may be periodic and non periodic.
Periodic to decrease info overload , non periodic
ex exceeding Credit limit
3.Demand and Response –Available on demand –
Customized Reports , Web Based , RDBMS query
4.Push Reports – Automatically pushed on desktops
ex Newsfeeds of competition, stock prices
33. Decision Support System (DSS)
• Non Routine Decisions
• Semi Structured Decisions – 50/50
• 2 Categories
-Model Based
- Data Based
• Used infrequently only when problems
/opportunity analysis
34. DSS
• Model Based – Use of Statistical Models – result
is know , arrive at correlation between 2 variables
– ex behavioural analysis – Cross and Up Sell in E
Commerce
• Data Based – Use Data from TPS /MIS to slice
/dice/ consolidate /replicate and arrive at new
knowledge which was not known
ex Yield Management System ( Dynamic ticket
pricing of Airlines ) based on optimization model
35. Components of DSS

36. Executive Information System (EIS)
• Decisions taken at Top level
• Totally unstructured decisions based on data ,
insights, intuition and experience
• Data is 2 types
- Internal Data – From DSS
- External Data – Sensex , Standard and Poor
type reports , Govt Policies , Industry Reports
• Dashboard is Graphical /Charts
37.
38. Topics:
• Understand concept of Knowledge
• Hierarchy of Knowledge
• Types of Knowledge – Explicit & Tacit
• Knowledge Types conversions
• Value of Knowledge
• Organizational Knowledge – Single & Double loop
• Use of Information Technology in Knowledge
• Introduction to AI – Expert Systems
• Expert Systems – Forward and Backward Chaining
Chapter 3 – Knowledge Management &
Expert Systems
39. What is Knowledge
• Knowledge is
- Knowhow
- Applied Information
- Information with Judgment
- Capacity for effective action
40. • Lets understand the Hierarchy of Knowledge
with reference to manufacturing of some
product using a machine in factory
• Here each level of personnel has a different
knowledge know how with context to his role
41. Hierarchy of Knowledge
Example: understand Hierarchy of Knowledge in a factory where machine is used to
Produce a good say bottle.
WHY
WHAT
HOW
Knowledge to take decision
• Understand the social context
• Stakeholders-people, customer, factory, other
external factors in addition to machine
CASE
WHY
Domain expert Knowledge
Deeper Knowledge
Common Knowledge
Understand the working of machine
in details to produce the bottle
Understand what good the machine is
Producing-Bottle
How to operate a machine
42. Types of Knowledge
Knowledge basically is of two types
1 . Explicit Knowledge – Can be expressed in
words and figures , essentially this knowledge
can be documented
2.Tacit – This knowledge cannot be documented
For organization to grow by continuous
innovation, Tacit knowledge has to be
continuously converted to Explicit knowledge
43. Knowledge Types Conversions
• Tacit to Explicit – for continuous innovation , Ex
Expert Systems
• Explicit to Tacit – Ex PhD Research –Start with
Literature review , find gaps and to tacit research
for further innovation
• Explicit – Explicit – Organizations copy best
knowledge practices from each other , ex use of
same type of Payroll System
• Tacit –Tacit –Two subject matter experts talk to
each other to increase the Tacit knowledge of
each other .
44. Value of Knowledge
• In knowledge economy , Knowledge has “money
“ value – Valuations of Startups in determined by
their Innovation (Knowledge).This knowledge has
to be continuously stored in Knowledge
Management System
• Newspapers /Websites provide information and
not knowledge .They in turn earn money from “
Ads” which is giving someone else’s information
• Knowledge creates wealth in today's economy
and is the greatest asset of any organization
45. Organizational Knowledge
• Organizational Learning Strategy is different for different
organizations .It creates new standards for operating
processes
• There are two types of Organizational learning
1. Single Loop – Get into deeper understanding of “Cause” in
the “Cause and Effect “ theory.Ex Earthquakes kill people
.Here you will get into understanding of Cause of
Earthquake and find solution
2.Double loop –You challenge the “ Cause “ . Ex Earthquakes
don’t kill people , Falling buildings do . Earthquakes don’t
kill people in Japan and US , but they still do in Indonesia
and other countries
46. Information Technology in Knowledge
Management
• Technology is used in Knowledge
Management in 4 ways
1. Create Knowledge – Use simulation and
design tools like CAD/CAM software , Virtual
Reality
2.Capture & Codify (Automate ) knowledge by
using Artificial Intelligence (AI) like Expert
Systems
47. Information Technology in Knowledge
Management
3. Share Knowledge – Use of GDSS ( Groupware
Software ) to share and increase knowledge
4.Distribute Knowledge – Using Office
Automation Systems , Intranets etc
Points 3 & 4 are part of all Information Systems
Point 1 & 2 are specific to Knowledge
Management Information System

49. Expert System
• The process of transfer of human expert
knowledge to a computer and thereafter
taking inputs of the expert advice from the
computer is called Expert System
• The components of Expert System as
described in next slides are
- Knowledge Base
- Inference Engine
- User Interface
50. Expert System - Conversion of Expert Knowledge
for Automatic Distribution of Advice to users
52. Organizations using Expert System
• Medical Diagnosis – ex WebMD ,
www.easydiagnosis.com
• Games –Chess /Cards – www.chess.com
• Coding
• Filing Income Tax Returns
53. Components of Expert Systems
• Inference Engine – Use of “Rules “ , “ What if
Analysis “ – This is “brain” of Expert System.
Apart from Rules , its other function is to “Search
“ the Knowledge Base.
• Knowledge Base – Domain Experts (ex Doctor)
provides knowledge to Knowledge (Data)
Engineer who codifies the knowledge in
Knowledge Base
• UI – Uses web , Text to Speech and Speech to Text
to get the expert advice to non expert user
54. Forward and Backward Chaining in
Inference Engine
• Inference Engine uses Forward and Backward
Chaining techniques for framing Rules and Search
from Knowledge Base
• Forward Engine – Starts with known facts and
asserts new facts
• Backward Chaining – Starts with goals and works
backwards to determine what facts must be
asserted so that goals can be achieved . It
essentially does hypothesis testing
55. Forward and Backward Chaining
Example
• A is initial condition – No one is in
Management Institute today
• A->B ( A implies B ) – Rule – If no one is in
Institute today , it must be holiday
• B (Result ) – It is holiday today
Forward Chaining – Given A and A->B , find B
Backward Chaining – Given B and A->B , find A
57. DECISION THEORY
ELEMENTS OF DECISION THEORY
TWO METHODS OF DECISIONS – UNDER
UNCERTAINTY AND UNDER RISK
TOPICS
58. DECISION THEORY IS A STATISTICAL
TOOL OR TECHNIQUE WHICH IS USED TO
SELECT THE BEST WAY OF DOING WORK
HELPS IN DECISION BY SELECTING THE
BEST OUTCOME OUT OF MANY
ALTERNATIVES USING DATA
DECISION THEORY
59. 2.STATES OF NATURE – MUTUALLY
EXCLUSIVE AND EXHAUSTIVE CHANCE
EVENTS. AT A TIME ONLY 1 CHANCE
EVENT WILL HAPPEN OUT OF FINITE
NUMBER OF EXHAUSTIVE EVENTS. IN A
TABLE , STATES OF NATURE USUALLY
ARE REPRESENTED AS “ ROWS”
ACTS OR ALTERNATIVES ARE UNDER
OUR CONTROL WHILE STATES OF
NATURE ARE NOT UNDER OUR CONTROL
EXAMPLE – “ STOCK” IS ALTERNATIVE
WHILE “DEMAND” IS STATE OF NATURE
FOUR ELEMENTS OF DECISION THEORY
60. 3. OUTCOME /RESULTS – THE SET OF
CONSEQUENCES RESULTING FROM ALL
ACTS & STATES OF NATURE
4. OBJECTIVE VARIABLES – QUANTITY
USED TO MEASURE AND EXPRESS THE
RESULT OF A DECISION PROBLEM LIKE
“PROFIT “ , “ LOSS”
THE 4 ELEMENTS ARE REPRESENTED IN
A TABLE CALLED PAY OFF TABLE (
PROFIT) OR OPPORTUNITY LOSS ( OR
REGRET ) TABLE
FOUR ELEMENTS OF DECISION THEORY
61. DECISION MAKING IS OF TWO TYPES
1. DECISION UNDER UNCERTAINTY-
HERE PROBABILITY IS NOT USED
2. DECISION UNDER RISK –HERE
PROBABILITY IS USED
METHODS OF DECISION
62. ARRANGE ALTERNATIVES & SCENARIOS
IN A TABLE – CALLED PAY OFF MATRIX /
REGRET MATRIX
ALTERNATIVES ARE USUALLY IN ROWS
AS A,B,C,D..
STATES OF NATURE ARE USUALLY IN
COLUMNS AS P,Q,R
CELLS OF TABLE CONTAIN THE PROFIT
(IN PAY OFF ) OR OPPURTUNITY LOSS (
IN REGRET ) TABLE
DECISION UNDER UNCERTAINTY
63. THREE TYPES ARE MOSTLY USED FOR ANALYZING THE PAY OFF TABLE TO
CHOOSE STRATEGY..
1 MAXIMAX – MAXIMIZE THE MAXIMUM POSSIBLE OUTCOME . ATTITUDE IS TO
TAKE RISK – OPTIMISTIC APPROACH .PICK THE HIGHEST OUTCOME
(RESULTS) OF EACH ALTERNATIVE AND THEN PICK THE BEST OUT OF THE
BEST OUTCOMES ACROSS ALTERNATIVES
2 MAXIMIN – MAXIMISE THE MINIMUM POSSIBLE OUTCOME – AVOID RISK –
PESSIMISTIC APPROACH. PICK THE LOWEST OUTCOME OF EACH
ALTERNATIVE AND THEN PICK THE HIGHEST AMONG THE CHOSEN ACROSS
ALTERNATIVES
3 MINMAX REGRET
IN BOTH THESE APPROACHES , ONLY COLUMNS ( ACTS ) ARE COMPARED TO GET
THE MAXIMUM OR MINIMUM OUTCOMES
TRICK OF ANALYSIS : BREAK THE WORD IN 2 PARTS AND GO FROM BACKWARD
TO FORWARD ANALYSIS OF TABLE .EXAMPLE MAXIMAX IS MAXI (FORWARD ) AND
MAXI (BACKWARD) MAXI I MAX
FIRST FIND THE MAXIMUM VALUE OF EACH COLUMN AND THE N FIND THE
MAXIMUM OF THOSE VALUES.
SIMILARLY MAXIMIN IS MAXI I MIN . FIRST FIND “ MIN ‘’ OF ACH COLUMN AND THEN
FIND “MAX” OR MAXIMUM OF THOSE VALUES
STATES OF NATURE ( ROWS ) ARE NOT CONSIDERED FOR MAXIMAX AND MAXIMIN
ANALYSIS
DECISION UNDER UNCERTAINTY
64. HIGHEST VALUE .THE RESULT IS
REGRET OR OPPORTUNITY LOSS VALUE
.THIS EXERCISE IS DONE FOR EACH
ROW
- THEN THE SAME PROCESS AS
MAXIMAX /MINIMAX IS APPLIED . IN
MINIMAX USING BACKWARD/FORWARD
RULE , FIRST THE MAXIMUM VALUE OF
EACH COLUMN ( EACH STRATEGY
INDIVIDUALLY ACROSS STATES OF
NATURE) IS FOUND , AND THEN GOING
FORWARD , THE MINIMUM VALUE IS
CHOSEN AS THE STRATEGY
DECISION UNDER UNCERTAINITY
65. LOSS TABLES IN THE NEXT SLIDES
ALTERNATIVES ARE REPRESENTED AS
A,B,C AND D WHILE STATES OF NATURE
ARE REPRESENTED AS P,Q,R AND S
WE HAVE TO FIND THE ALTERNATIVE
(A,B,C OR D) UNDER MAXIMAX , MAXIMIN
