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.

2. What is ADO.NET
• ADO.NET (Active Data Objects) is the data access
component of the .NET Framework
• Used to develop data bound Windows Forms and Web Forms
• Like other components of the .NET Framework,
ADO.NET consists of a set of classes that
interact to provide the required functionality
• VS 2008 (and greater) and .NET 2.0 (and greater) make
development much easier
• ADO.NET classes are divided to two primary components
• Data Providers handle communication with the data source
• Data Sets represent the actual data from the data source
3. ADO.NET Object Model
• The primary objects in the ADO.NET object model
• The true reality of the class library is
considerably more complicated
4. Data Providers
• Data Provider components are specific to a data
source
• A generic provider that can communicate
with any OLE DB data source (Access etc)
• An SQL Server provider, optimized
for SQL Server 7, 2000 & 2005
• An ODBC provider that can communicate
with an ODBC data source (MySQL etc)
• An Oracle provider, optimized for access to Oracle
• Data Providers contain the same objects
• SqlConnection, OleDbConnection, OracleConnection etc
5. SqlConnection
The SqlConnection class is used to establish a
connection to a SQL Server database. The SqlConnection
class is used for opening connections, setting or
retrieving properties of a connection, or handling
connection-related events.
Connection objects represent the physical connections
to data sources
• Their properties determine the data provider,
the data source, the database to connect to
and the string to be used during connection
– Their methods are fairly simple. You can open
and close the connection, change the database
and manage transactions
6. SqlCommand
The SqlCommand class is used to execute SQL statements
or stored procedures against a SQL Server database. The
SqlCommand class can execute statements or stored
procedures that do not return values, or that return
single values, XML, or datareaders.
• Command objects can be executed against a connection
They are also used by DataAdapter objects to handle the
communication requirements of DataSet objects.
7. SqlDataReader
The SqlDataReader class provides forward-only, read-
only only access to a set of rows returned from a SQL
Server database. Datareader provide high-performance
access to read-only data and is the
best choice for accessing data to be displayed in
ASP.NET.
• DataReader objects can not be created directly
in code as they are constructed by calling the
ExecuteReader method of a Command object
8. SqlDataAdapter
The SqlDataAdapter class is used as a bridge between the
DataSet class and SQL Server. You can use the
SqlDataAdapter class to create a dataset from a given
SQL statement or stored procedure represented by a
SqlCommand instance, to update the back-end SQL Server
database based on the contents of a dataset, or to
insert rows into or delete rows from a SQL Server
database.
• It provides an automated bridge between
a Connection object and a DataSet object
• A DataAdapter object contains four Command
objects, one each, for SELECT, UPDATE,
INSERT and DELETE based SQL statements
11. Data Sets
• The DataSet object is a memory resident copy of data
• The DataSet can be considered a somewhat simplified
relational database as it models tables and any
relationships between them
• The DataSet is always disconnected from the data source
• The DataSet is composed of two primary objects
• The DataTableCollection, accessed
through the Tables property
• The DataRelationCollection, accessed
through the Relations property
