Use of High Resolution temporal satellite imageries and Geographical Information System (GIS) provide us present and past status of extensions and Landuse change in oukskirts of urban centres. The present paper is an attempt to analyze the temporal urban growth and landuse change of Aligarh city using Survey of India Topographical Map surveyed in 1971 and IKONOS satellite data of various time periods from 2004, 2009 and 2014. The result shows that in 1971 the urban built-up land of the city based on SOI Topographical Map was 2224.6555 hectare, based on interpretation of IKONOS satellite imagery of 2004, 2009 and 2014 , the urban built-up area of the city is 4724.7614 hectare in 2004, 5872.6774 hectare in 2009 and 7059.8875 hectare in 2014 respectively. This has increased to 2500.1059 hectare in a period of 33 years from 1971 to 2004 and in the period from 2004-2009 and 2009-2014 it has increased by 1148 hectare and 1187.211 hectare respectively. Agricultural land, Orchard/Plantations and water bodies to built-up (urban) has been calculated in GIS and it has been observed that there is a tremendous increase in the built-up urban area. The loss of prime arable land, orchard/plantation and water bodies has been converted in to built-up urban land. The digital database created for urban growth and landuse change of Aligarh city, Uttar Pradesh, India using multi-date data in Arc-GIS software would be very useful for urban development authorities, planners, decision makers for better landuse planning and management for proposed landuse programmes.
A GIS BASED STUDY OF CHANGE DETECTION OF URBAN SPRAWLS OF JAMMU, J&K, INDIA
Urban growth is a worldwide phenomenon but the rate of urbanization is very fast in developing country like India. The rapid urbanization has resulted to plan and develop urban areas in a logical manner as the increasing population is demanding rapid increase of urban centre. It is prerequisite for any urban area to have a GIS based map. This research paper seeks to detect, analyse and mapping of the urban built-up changes/growth using maps generated through remote sensing and geospatial techniques. Jammu as one of the capital city of state Jammu and Kashmir has experienced rapid expansion of urban area during last three decades. Therefore, an attempt has been made to project the urban built-up changes between (1997-2017) using maps generated in GIS environment, to assist the state government, policy makers and urban planners to have effective and efficient planning of the urban areas to formulate better future plans of urban growth of the city.

Cities are hubs of economic activity, innovation, and employment. People from rural areas migrate to cities in search of more diverse income opportunities. The increasing demand for space in cities puts pressure on urban land, resulting in urban built-up expansion. The immediate impact of urban expansion can be seen on the peri-urban outskirts, where land resources are being altered and converted from one use to another due to increased demand for urban land uses, particularly residential uses. As a result, this study examines urban expansion and changes in land use land cover in one of the fastest-growing urban centres in Western Uttar Pradesh, India. A GIS-based analysis approach was used for this. From 1980 to 2018, various satellite and analogue maps were used to map land use and land cover at various times. In ArcGIS software, a change detection technique incorporating a simple image differencing method was used for land use land cover change analysis. The findings indicate a significant increase in built-up classes over the last four decades. A significant amount of agricultural land was lost as a result of the expansion. There is a dissimilar pattern of landuse changes, with the change being most noticeable on the city's northern and eastern outskirts, which is a source of concern for city planners.

Remote sensing and GIS technology are very useful in mapping of natural resources and urban studies. Urbanization being a dynamic force, its impact is seen in both spatial and temporal variation of urban land use. Most of the urban areas are increased due to urbanization and thereby creating urban sprawl. Bhubaneswar is the capital of the state of Odisha, between 20 ̊ 12' N and 20 ̊ 23' N latitudes and 85 ̊ 44' E and 85 ̊ 54' E longitudes. Land use /land cover maps were prepared by using satellite data of IRS-1D PAN (2000), Cartosat-1 (2005) and IRS-P6 LISS-IV (2010) and ground checks during field survey. The changes in urban land use pattern over a period of time were studied using multidate and multisensor (2000-2010) remote sensing data. The main aim of this study is to analyze the spatio-temporal changes of land use in the city as well as mapping urban sprawl. Based on the urban land use /land cover analysis, spatial growth of urban centers and the population hav...
Today more than half of the world's population resides in urban areas whereas in case of India it's above thirty percent. But as per the census of 2011 the absolute increase of population is more in urban areas in comparison to rural areas. The latest census of 2011 reveals that about 55 percent of the total population of Panchkula resides in urban area which is above the national average. All this has resulted into physical expansion of the urban area. This physical urban growth is the process of transformation of land use from non-urban or rural to urban use over a period of time. This physical expansion can be radial or sectoral in the periphery of an urban centre. The detection and quantification of this urban growth help urban planning for sustainable future. The present study aims to measure and quantify the urban expansion of Panchkula over a period of one decade using geospatial technology and compare the attributes of urban expansion with those of growth of populati...
MONITORING URBAN EXPANSION AND LAND USE/LAND COVER CHANGES OF AGARTALA CITY, TRIPURA, INDIA
Indian Journal of Regional Science, 2020
In developing countries like India the growth of urban area generally depends on the importance of the economic, administrative and the institutional functions of the area. With the increase of small and medium or big industries in and around the area, market places, business centres, establishment of different offices, institutions, the importance of the area grows fast and primarily to avail the opportunity of various income generation avenues, people start to migrate from rural to the urban areas. The economic prosperity, better infrastructural facilities, relatively good governance and continuous rural to urban migration ultimately generate rapid urban growth along with urban sprawls, uneven population density, irregular growth of urban morphology as well as environmental degradation, etc. In modern urban research, Remote Sensing and Geographical Information System are used to monitor the growth and changing scenario of an urban area. Using sequential time-series satellite data land use/cover changes can easily be generated, which are essential for the assessment of urban growth. The present research deals with the pace of assessment of urbanisation, urban growth and land use/land cover dynamics of Agartala City through an integrated approach of Remote Sensing and Geographical Information System. Landsat Satellite imageries of two different time periods, i.e., Landsat Thematic Mapper (TM) and Enhance Thematic Mapper (ETM) have been acquired and quantified the land use/land cover changes in Agartala City during 1991 to 2015. The changing scenario of land use/cover of the city points out that Agartala has been gradually changing. The images of the study area have been categorised into five different classes, viz. built-up area, water body, open space, vegetation cover, and agricultural land. Spatially, vegetative cover and open space, a good part of low-lying marshy land and water bodies have been converted into built-up area in Agartala City. The study reveals that the city is expanding towards north-south direction due to the presence of the airport in the north and National Highway-8 along the periphery of the city in the south. The study also highlights the importance of digital change detection techniques to identify the nature and locational changes in the Agartala City area. It shall contribute to forecast possible future changes in growth patterns of the city as well as the development of sustainable urban land use planning decisions.
Quantification of Urban Expansion Using Geospatial Technology—A Case Study in Bangalore
Advances in Remote Sensing, 2015
Quantification of urban expansion helps us to understand human induced effects on the environment in a temporal scale. Growing urbanization in Bangalore has resulted in demand for more space and resources. Since last 15 years the landuse and landcover of Bangalore area has been changed drastically due to increase in settlement, urban infrastructure, opening of roads and metros etc. Using geospatial tools, we studied the changes in landuse and landcover over 19 years (1992-2011) of period and changes in transport network over 41 years (1970-2011) in parts of Bangalore. Thus, the current study shows that the built-up area has been increased drastically, tree cover areas have been converted to agricultural lands and agricultural lands to built-up areas due to urbanization. There are also changes in drainage pattern, transport network and encroachment of water bodies. Thus the whole environment is getting affected adversely due to unplanned and rapid urban sprawl.
Study of urban land use dynamics in Srinagar city using geospatial approach
Bulletin of Environmental and Scientific Research, 2012
Rapid urbanization Land use and land cover change has been one of the most obvious drivers of global change over the last few centuries. Changes in land use and land cover can have significant ecosystem consequences such as impacts on global and regional climate and biogeochemical cycles. In this paper, the changes in the land use/land cover and its impact on biodiversity have been monitored over Srinagar city in Kashmir Valley for the period of 31 years (1996-2007). We used Landsat MSS 1976, ETM 2001, 1990 and IKONOS 2007 (Google earth) images, to identify urbanized areas and to quantify urban expansion in the above mentioned city i.e., Srinagar. The results showed that over the 31year period, the land use and land cover in the study area experienced significant changes. The urban area of the city has increased significantly since the year 1990 till 2007. Since 1976 the built up in the Srinagar city has increased from 8.065 sq. km to 29.23 sq. km in the year 2007. Further analysis showed that there were significant changes in land use pattern, which has resulted in the loss of forest area, open spaces, etc. Our findings conclude that an abrupt shift in land use from ecologically important features to large-scale built up environment, besides Srinagar city became hence. Hence, strict policy measures are required to control the abnormal growth of the city.

In this study, the metropolitan area of Delhi considered utilizing Landsat images from 1991 and 2011 in order to recognize changes to land cover. The changes in temporal land cover have an effect on the climate and its urban landscape. A change detection analyses the nature, extent of urban sprawl due to changes in land cover, land use/land cover (LULC) and twenty years of overtime change detection. This work explores the significant growth of the city at the expense of unbuilt land in its region. In the study area, there was a substantial land exchange between numerous LULC groups, not just because of the development of the city area. The accuracy assessment of the supervised classification showed good accuracy for 1991 and 2011 respectively, which was 96.31 and 97.35 percent. The twenty-year growth rate in the Delhi area was 11%. The study showed a dramatic shift in urban areas and agricultural land in Delhi and it contributed to 54116.2 hectares declining to 37243.17 hectares in 1991 and 2011 respectively.
