    Urban density represents the amount of land occupied by a number of residents and an important factor in understanding how cities function. It is one of the essential components in measuring urban sprawl. The urban density index provides a measure of how much land is consumed per capita for a patch of new development. It is commonly asserted that higher density cities are more sustainable than low density cities because it consumes more land for each resident leaving less of the landscape able to function in other capacities. While some researcher argue that low-density urban area contributed to sprawl, others have counter that higher density results in more negative impact. Characterizing urban sprawl by using density index requires suitable and proper technique. This research attempts to study the measurement of sprawl by using density index with Remote Sensing and Geo-information System (GIS) approach. The SPOT-5 images with 2.5 meters resolution were used and combined with GIS database to analyse the growth of sprawl in Kuala Lumpur metropolitan due to its high-density development. To achieve a better urban development and infrastructure planning in the future, it is crucial for the City Hall to know sprawl phenomenon in Kuala Lumpur, its types, distribution, factors, and the way it is likely to move in the years to come. By using Remote Sensing and GIS, high density area and low density area in Kuala Lumpur can be analysed and compared. The findings show that Kuala Lumpur is a sprawling city. Suitable measures can be adopted by responsible authority to overcome urban sprawl issues in Kuala Lumpur. It is anticipated that this research will provide a new direction in urban sprawl studies and represent a robust analytic approach for characterizing urban development in the city scale at once as well as promoting a city via Remote Sensing and GIS technology

    Characterizing urban sprawl using spatial measures requires a concise definition of what constitutes sprawling urban spatial patterns. This research attempt to study a measurement of defining sprawl by using leapfrog development index through remote sensing and GIS approach. The IKONOS pan-sharpened and SPOT-5 with 1 and 2.5 meter resolution were used and combined with Geographical information system (GIS) database to analyze the geospatial indicators using the leapfrog development index. Kuantan city has been selected as a study area to examine the leapfrog development based on land use pattern for year 2012. The findings shows Kuantan has identified as non-sprawling cities with result from characterization in leapfrog development that has been tested. However, the gap between sprawl and non-sprawling was very low. It is anticipated this research will provide a new direction in sprawl nationally that address finding of sprawl at the atomic level and present a robust analytical approach for characterizing urban development in city scale at once promoting a city via GIS & Remote Sensing technology respectively towards Digital and Green cities

    The purpose of this paper is to study the nature of on-going transition in developing countries, the quality and uncertainty of existing urbanisation forecast. This paper provides a broad overview on the existing urban growth process and discussing the available evidence on patterns and trends of growth respectively. Two capital cities namely Phnom Penh in Royal Government of Cambodia and Kuala Lumpur in Malaysia were used in assessing the process of urban growth of developing countries. Two different pattern of urban growth process were compared and analysed to establish a real development scenario. Phnom Penh and Kuala Lumpur development assess the challenges associated with urban growth that lie ahead and identify the key area of policy that been required. It ends by highlighting the growing needs for vibrant urban research agenda to adequate future policy

    While remote sensing applications represent a major though still underused source of urban data, the proposed combination between remote sensing and Geo-information System (GIS) in urban and regional planning is not fully explored. In order to measure changes in land use, the need of platform in monitoring, recording, and predicting the changes is necessary for planners and developers. In advance technology of mapping process, remote sensing and GIS as tools for urban planning are already recognised. But, due to lack of implementation and awareness about the benefits of these tools, these terms look unusual. Therefore, this paper reviews the history of remote sensing and GIS in urban applications, technical skills and the challenges, and future development of remote sensing and GIS especially for urban development particularly in developing countries
