1. INTRODUCTION
To study and compare the demographic change between the above year Land use is obviously
constrained by environmental factors such as soil characteristics, climate, topography, and
vegetation. But it also reflects the importance of land as a key and finite resource for most human
activities including agriculture, industry, forestry, energy production, settlement, recreation, and
water catchment and storage. Land is a fundamental factor of production, and through much of
the course of human history, it has been tightly coupled with economic growth. Often improper
Land use is causing various forms of environmental degradation. For sustainable utilization of the
land ecosystems, it is essential to know the natural characteristics, extent and location, its quality,
productivity, suitability and limitations of various. Land use is a product of interactions between a
society's cultural background, state, and its physical needs on the one hand, and the natural
potential of land on the other (Balak Ram and Kolarkar 1993). In order to improve the economic
condition of the area without further deteriorating the bio environment, every bit of the available
land has to be used in the most rational way.

4. LAND SAT
7 Imagery The spectral resolution of each of the 7 bands, plus the panchromatic band, are
summarized in the following table, along with a description of the spatial resolution and the
primary use of data
4.1. Band 1
The spectral response of Band 1 is in the visible portion of the electromagnetic spectrum that
corresponds with blue-green light. Energy at this portion of the electromagnetic spectrum is easily
scattered by particles in the atmosphere, often giving images in this band a hazy appearance. This
band is capable of being transmitted through water and is especially sensitive to particles
suspended in water (such as sediments and algae). Data from this band can be used with bands 2
and 3 to create "true" color composite images, which most closely approximate how the scene
would appear to the human eye.
Advanced Computing: An International Journal (ACIJ), Vol.7, No.1/2, March 2016
32
4.2. Band 2
The spectral response of Band 2 is in the visible portion of the electromagnetic spectrum that
corresponds with green light. It can be used with bands 1 and 3 to create "true" color composite
images.
4.3. Band 3
The spectral response of Band 3 is in the visible portion of the electromagnetic spectrum that
corresponds with red light. It is also one of the three component bands used to create "true" color
composite images.
4.4. Band 4
The spectral response of Band 4 is in the Near Infrared (NIR) portion of the electromagnetic
spectrum. This form of infrared sits just outside the visible red light portion of the
electromagnetic spectrum. This form of radiation is reflected to a high degree off leafy vegetation
since chlorophyll (the green pigment in green vegetation) reflects much of the NIR that reaches it
(it has a high albedo in this band)
4.5. Band 5
The spectral response of Band 5 is in the Middle Infrared (Mid-IR) portion of the electromagnetic
spectrum. This portion of the spectrum is sensitive to variations in water content in both leafy
vegetation and soil moisture. This band allows an observer to distinguishes between clouds
(which appear dark) and bright snow covr (which appear light). Sensors in this band also respond
to variations in ferric iron (Fe2O3) in rocks and soils, showing higher reflectance as iron content
increases. This allows one to use these data to determine mineral content and soil types from
space
4.6. Band 6
The spectral response of Band 6 is in the Thermal Infrared portion of the electromagnetic
spectrum. Thermal infrared is radiation that is detected as heat energy, therefore the thermal Band
6 on the ETM+ sensor can distinguish temperature difference of about 0.6 Celsius, which allows
it to detect relatively small differences in land and water surface temperatures. This makes the
thermal IR band useful for a variety of purposes. For example, using band 6 data, researchers can
discriminate among rock types whose thermal properties show differences in temperature near the
surface. This assists researchers in creating geologic mapping of land surfaces from space. This
data supports agricultural and mineral exploration efforts. ETM Band 6 data can detect changes in
ground temperature due to moisture variations, assisting in drought planning, flood forecasting,
and agricultural assessment. The cooling effect of water evaporating from vegetation can be
detected, assisting in efforts to map land use characteristics of a region.
4.7. Band 7
Spectral response of Band 7 is in the Middle Infrared (Mid-IR) portion of the electromagnetic
spectrum. This portion of the electromagnetic spectrum is sensitive to moisture and thus responds
to the moisture contents in soils and vegetation. The sensitivity to moisture contents is suited to
detecting certain water-loving minerals, such as clays, in geologic settings. This band is also
useful in detecting moisture levels in leafy vegetation, which can change under certain
environmental conditions (e.g. drought, pollution, insect infestation) and thus provides a means to
monitor productivity and identify agricultural areas that are under stress.

4.8. Panchromatic
0.52 to 0.90 pedometers black and white sensor with a 15 m spatial resolution. The higher
resolution of this data assists land-use researchers by making identification of smaller objects
easier. Items smaller then 30 m will appear fuzzy or ill defined in the 30 m bands of the ETM+.
The 15m resolution of the panchromatic band will allow researchers to make better
determinations of land use and will assist in producing accurate land use maps.

5.CHANGE DETECTION ANALYSIS:
Change detection is the use of remotely sensed imagery of a single region, acquired on at least
two dates, to identify changes that might have occurred in the interval between the two dates.
Those two dates can be years apart, for example to track changes in urbanization, or days apart,
for example to track changes from a volcanic eruption. Change detection has been applied to
examine effects such as land use changes caused by urban and suburban growth, effects of natural
disasters (such as floods, forest and range fires), and impacts of insect infestations upon forest
cover, for example. Change detection requires application of algorithms that are specifically
designed to detect meaningful changes in the context of false alarms— ostensible changes that
are, in reality, simply artifacts of the imaging process. A critical prerequisite for application of
change detection by remote sensing is the identification of suitable pairs of images representing
the same region. The analyst must assure that (1) the two images register (that they match exactly
when superimposed), (2) that they were acquired during the same season, especially if use to
track changes in vegetation, and (3) that there are no significant atmospheric effects. In brief, the
two images must be compatible in every respect-- scale, geometry, resolution – otherwise the
change detection algorithm will interpret incidental differences in image characteristics as
changes on the landscape. There has been much research devoted to evaluating alternative change
detection algorithms. A basic distinction between pre-classification and post-classification
comparisons captures a primary division in the natures of the approach. Post-classification change
detection defines changes by comparing pixels in a pair of classified images (in which pixels have
already been assigned to classes). Post classification change detection typically reports changes as
a summary of the “from-to” changes of categories between the two dates. Pre-classification
change detection examines differences in two images prior to any classification process. Pre-
classification algorithms typically permit the analyst to set thresholds for the magnitude of
changes to be detected and highlighted. This tutorial will introduce a simple procedure using
ArcGIS Image Analysis for pre-classification change detection— other approaches are available
for the more experienced student, and to examine In GIS ,map overlay /intersection
operations were used to bring out the changes occurred in the land use/land cover for various
periods. To achieve the said ,land use/land cover map of the year 2003 was superimposed over
year 2008.It was found from the analysis that there 12 combination of changes,while the
possibilities are 144 combination.

6. IMPACTS OF LAND USE CHANGE
Urban Dynamics research in landscape characterization, urban growth models, and geographic
understanding provides the data necessary for analyzing the impacts of population growth and
land use change. This information can be used to analyze the causes of urban congestion,
pollution, and loss of natural resources. Each of these impacts is linked to changes in the extent of
urban, agricultural ,and forested lands, and (or)transportation systems. Planners use Urban
Dynamics data to evaluate environmental impacts, to delineate urban growth boundaries or
service areas, to develop land use zoning plans, and to gauge future infrastructure requirements.
Traffic congestion, a common malady of urbanization, is the result of urban growth, increases in
population density, and out-dated transportation infrastructure. By evaluating trends associated
with land use change over time, solution sto traffic congestion may be obtainable. Another
specific application of UDR data is the correlation of air pollution records with the temporal
database to determine if control strategies for reducing pollution have been effective. Many
pollution control strategieshave been used in the past three decades. Correlation between land use
change and pollution helps researchers establish positive or negative trends that indicate whether
pollution control strategies have been successful. With this information, policy makers, resource
managers, and the public can make appropriate changes for the future. Hydrologists can use
Urban Dynamics data to evaluate new water sources for future urbanization and to analyze.

agriculture, and forest lands are used to identify and quantify historictrends in sediment and
nutrient loads in waters draining into theChesapeake Bay.Geologists use data on land use
change to evaluate the availability of building materials, such as sand, gravel,and cement.
Geologists also use data on existing hazards to correlatewith the UDR data to predict theimpacts
of future natural disasters and the potential damage they may cause.Baltimore
6.2 Future risks
Madurai is facing similar challenges in relation to safe guarding its food security as India is
facing as a whole: in particular, rising demand, seasonal water variability, and rising temperatures
due to climate change could have an impact on its food security due to falling yields and rising
prices. For example, whilst no projections are available analyzing the implications of climate
change for the agricultural areas immediately surrounding city, projections for Western Ghat and
Coastal regions of the State out to 2030 suggest maize and sorghum yields are likely to be
negatively impacted by 2030, and increases in temperature and humidity may lead to livestock
rearing becoming a more cost intensive with livelihood implications for more marginal farmers.
However, the assessment identifies that further analysis will be needed in the future to better
understand Madurai’s food system to inform decision making. This should include analysis of the
city’s reliance on and ability to draw on food sources within and outside its immediate catchment,
the strength of regional food distribution and logistics systems, and further analysis of the
interface between food systems and Madurai’s blue infrastructure, as well further analysis of the
potential impacts of climate change (and its link to livelihoods) within Madurai’s catchment. The
State Climate Change Action Plan will include a sector implementation plan for agriculture to
address this.
7.CONCLUSION
The urban area of Madurai city has increased tremendously within the 2003-2013(10)years. This
resulted from rural-urban migration. Madurai is one of the most developing cities in Tamilnadu,
after Chennai. Education institutions, industries, and factories etc are located and upcoming here.
As a result, rural-urban migration has been characterizing in Madurai city. The overall percentage
increased during the period of 5 years about 18%, 14.2%, and 1.14%. built-up land, Land with
Scrub Sett, Corp land Comm. & Industrial activity and Airport respectively. There has been
decrease in the mixedbulit up land, vacand land,52%,25% and 13%.water body and River with no
change respectively.
The results of this study were based on Image classification and its interpretation. The mapping of
the urban development of Madurai town shows the development of urban lands had brought
changes in other part of the city as well. The interpretation of multi-date satellite helped in the
preparation of urban changes map of the study area. The decrease in agricultural/Scrub area is due
to conversion of urban land use or discontinuation of agricultural lands. The Barren land has been
increase as cultivable land is left with discontinuation of cultivation due to lack of irrigation
facility and seasonal variations are made them to be available as such. Similar studies can be
under taken for other major cities also to estimate to make necessary arrangement to plan
accordingly to preserve the natural environment.

INTRODUCTION To study and compare the demographic change between the above year Land use is obviously constrained by environmental factors such as soil characteristics, climate, topography, and vegetation. But it also reflects the importance of land as a key and finite resource for most human activities including agriculture, industry, forestry, energy production, settlement, recreation, and water catchment and storage. Land is a fundamental factor of production, and through much of the course of human history, it has been tightly coupled with economic growth. Often improper Land use is causing various forms of environmental degradation. For sustainable utilization of the land ecosystems, it is essential to know the natural characteristics, extent and location, its quality, productivity, suitability and limitations of various. Land use is a product of interactions between a society's cultural background, state, and its physical needs on the one hand, and the natural potential of land on the other (Balak Ram and Kolarkar 1993). In order to improve the economic condition of the area without further deteriorating the bio environment, every bit of the available land has to be used in the most rational way.

METHODOLOGY The study is based on secondary data, the satellite imagery has downloaded .The clipped satellite imagery has used to prepare the land use and land cover map using supervised classification. 4. LAND SAT 7 Imagery The spectral resolution of each of the 7 bands, plus the panchromatic band, are summarized in the following table, along with a description of the spatial resolution and the primary use of data 4.1. Band 1 The spectral response of Band 1 is in the visible portion of the electromagnetic spectrum that corresponds with blue-green light. Energy at this portion of the electromagnetic spectrum is easily scattered by particles in the atmosphere, often giving images in this band a hazy appearance. This band is capable of being transmitted through water and is especially sensitive to particles suspended in water (such as sediments and algae). Data from this band can be used with bands 2 and 3 to create "true" color composite images, which most closely approximate how the scene would appear to the human eye.
  • 4. Advanced Computing: An International Journal (ACIJ), Vol.7, No.1/2, March 2016 32 4.2. Band 2 The spectral response of Band 2 is in the visible portion of the electromagnetic spectrum that corresponds with green light. It can be used with bands 1 and 3 to create "true" color composite images. 4.3. Band 3 The spectral response of Band 3 is in the visible portion of the electromagnetic spectrum that corresponds with red light. It is also one of the three component bands used to create "true" color composite images. 4.4. Band 4 The spectral response of Band 4 is in the Near Infrared (NIR) portion of the electromagnetic spectrum. This form of infrared sits just outside the visible red light portion of the electromagnetic spectrum. This form of radiation is reflected to a high degree off leafy vegetation since chlorophyll (the green pigment in green vegetation) reflects much of the NIR that reaches it (it has a high albedo in this band) 4.5. Band 5 The spectral response of Band 5 is in the Middle Infrared (Mid-IR) portion of the electromagnetic spectrum. This portion of the spectrum is sensitive to variations in water content in both leafy vegetation and soil moisture. This band allows an observer to distinguishes between clouds (which appear dark) and bright snow covr (which appear light). Sensors in this band also respond to variations in ferric iron (Fe2O3) in rocks and soils, showing higher reflectance as iron content increases. This allows one to use these data to determine mineral content and soil types from space 4.6. Band 6 The spectral response of Band 6 is in the Thermal Infrared portion of the electromagnetic spectrum. Thermal infrared is radiation that is detected as heat energy, therefore the thermal Band 6 on the ETM+ sensor can distinguish temperature difference of about 0.6 Celsius, which allows it to detect relatively small differences in land and water surface temperatures. This makes the thermal IR band useful for a variety of purposes. For example, using band 6 data, researchers can discriminate among rock types whose thermal properties show differences in temperature near the surface. This assists researchers in creating geologic mapping of land surfaces from space. This data supports agricultural and mineral exploration efforts. ETM Band 6 data can detect changes in ground temperature due to moisture variations, assisting in drought planning, flood forecasting, and agricultural assessment. The cooling effect of water evaporating from vegetation can be detected, assisting in efforts to map land use characteristics of a region. 4.7. Band 7 Spectral response of Band 7 is in the Middle Infrared (Mid-IR) portion of the electromagnetic spectrum. This portion of the electromagnetic spectrum is sensitive to moisture and thus responds to the moisture contents in soils and vegetation. The sensitivity to moisture contents is suited to detecting certain water-loving minerals, such as clays, in geologic settings. This band is also useful in detecting moisture levels in leafy vegetation, which can change under certain environmental conditions (e.g. drought, pollution, insect infestation) and thus provides a means to monitor productivity and identify agricultural areas that are under stress.

The higher resolution of this data assists land-use researchers by making identification of smaller objects easier. Items smaller then 30 m will appear fuzzy or ill defined in the 30 m bands of the ETM+. The 15m resolution of the panchromatic band will allow researchers to make better determinations of land use and will assist in producing accurate land use maps.

Advanced Computing: An International Journal (ACIJ), Vol.7, No.1/2, March 2016 34 5.CHANGE DETECTION ANALYSIS: Change detection is the use of remotely sensed imagery of a single region, acquired on at least two dates, to identify changes that might have occurred in the interval between the two dates. Those two dates can be years apart, for example to track changes in urbanization, or days apart, for example to track changes from a volcanic eruption. Change detection has been applied to examine effects such as land use changes caused by urban and suburban growth, effects of natural disasters (such as floods, forest and range fires), and impacts of insect infestations upon forest cover, for example. Change detection requires application of algorithms that are specifically designed to detect meaningful changes in the context of false alarms— ostensible changes that are, in reality, simply artifacts of the imaging process. A critical prerequisite for application of change detection by remote sensing is the identification of suitable pairs of images representing the same region. The analyst must assure that (1) the two images register (that they match exactly when superimposed), (2) that they were acquired during the same season, especially if use to track changes in vegetation, and (3) that there are no significant atmospheric effects. In brief, the two images must be compatible in every respect-- scale, geometry, resolution – otherwise the change detection algorithm will interpret incidental differences in image characteristics as changes on the landscape. There has been much research devoted to evaluating alternative change detection algorithms. A basic distinction between pre-classification and post-classification comparisons captures a primary division in the natures of the approach. Post-classification change detection defines changes by comparing pixels in a pair of classified images (in which pixels have already been assigned to classes). Post classification change detection typically reports changes as a summary of the “from-to” changes of categories between the two dates. Pre-classification change detection examines differences in two images prior to any classification process. Pre- classification algorithms typically permit the analyst to set thresholds for the magnitude of changes to be detected and highlighted. This tutorial will introduce a simple procedure using ArcGIS Image Analysis for pre-classification change detection— other approaches are available for the more experienced student, and to examine In GIS ,map overlay /intersection operations were used to bring out the changes occurred in the land use/land cover for various periods. To achieve the said ,land use/land cover map of the year 2003 was superimposed over year 2008.It was found from the analysis that there 12 combination of changes,while the possibilities are 144 combination.

IMPACTS OF LAND USE CHANGE Urban Dynamics research in landscape characterization, urban growth models, and geographic understanding provides the data necessary for analyzing the impacts of population growth and land use change. This information can be used to analyze the causes of urban congestion, pollution, and loss of natural resources. Each of these impacts is linked to changes in the extent of urban, agricultural ,and forested lands, and (or)transportation systems. Planners use Urban Dynamics data to evaluate environmental impacts, to delineate urban growth boundaries or service areas, to develop land use zoning plans, and to gauge future infrastructure requirements. Traffic congestion, a common malady of urbanization, is the result of urban growth, increases in population density, and out-dated transportation infrastructure. By evaluating trends associated with land use change over time, solution sto traffic congestion may be obtainable. Another specific application of UDR data is the correlation of air pollution records with the temporal database to determine if control strategies for reducing pollution have been effective. Many pollution control strategieshave been used in the past three decades. Correlation between land use change and pollution helps researchers establish positive or negative trends that indicate whether pollution control strategies have been successful. With this information, policy makers, resource managers, and the public can make appropriate changes for the future. Hydrologists can use Urban Dynamics data to evaluate new water sources for future urbanization and to analyze. 6.1 water pollution A problem common to urban areas, industrial sites, and agricultural lands.

Geologists also use data on existing hazards to correlatewith the UDR data to predict theimpacts of future natural disasters and the potential damage they may cause.Baltimore 6.2 Future risks Madurai is facing similar challenges in relation to safe guarding its food security as India is facing as a whole: in particular, rising demand, seasonal water variability, and rising temperatures due to climate change could have an impact on its food security due to falling yields and rising prices. For example, whilst no projections are available analyzing the implications of climate change for the agricultural areas immediately surrounding city, projections for Western Ghat and Coastal regions of the State out to 2030 suggest maize and sorghum yields are likely to be negatively impacted by 2030, and increases in temperature and humidity may lead to livestock rearing becoming a more cost intensive with livelihood implications for more marginal farmers. However, the assessment identifies that further analysis will be needed in the future to better understand Madurai’s food system to inform decision making. This should include analysis of the city’s reliance on and ability to draw on food sources within and outside its immediate catchment, the strength of regional food distribution and logistics systems, and further analysis of the interface between food systems and Madurai’s blue infrastructure, as well further analysis of the potential impacts of climate change (and its link to livelihoods) within Madurai’s catchment. The State Climate Change Action Plan will include a sector implementation plan for agriculture to address this. 7.CONCLUSION The urban area of Madurai city has increased tremendously within the 2003-2013(10)years. This resulted from rural-urban migration. Madurai is one of the most developing cities in Tamilnadu, after Chennai. Education institutions, industries, and factories etc are located and upcoming here. As a result, rural-urban migration has been characterizing in Madurai city. The overall percentage increased during the period of 5 years about 18%, 14.2%, and 1.14%. built-up land, Land with Scrub Sett, Corp land Comm. & Industrial activity and Airport respectively. There has been decrease in the mixedbulit up land, vacand land,52%,25% and 13%.water body and River with no change respectively. The results of this study were based on Image classification and its interpretation. The mapping of the urban development of Madurai town shows the development of urban lands had brought changes in other part of the city as well. The interpretation of multi-date satellite helped in the preparation of urban changes map of the study area. The decrease in agricultural/Scrub area is due to conversion of urban land use or discontinuation of agricultural lands. The Barren land has been increase as cultivable land is left with discontinuation of cultivation due to lack of irrigation facility and seasonal variations are made them to be available as such. Similar studies can be under taken for other major cities also to estimate to make necessary arrangement to plan accordingly to preserve the natural environment.
