With urban populations and their footprints growing globally, the need to assess the dynamics of the urban environment increases. Remote sensing is one approach that can analyze these developments quantitatively with respect to spatially and temporally large scale changes. Remote sensing techniques provide an important means for understanding urban environments. With a synoptic view and repeat coverage of a large geographic area, remotely sensed data have been applied extensively to analyze urban environments. The use of a synthetic index of urban environmental quality, derived from environmental, and ecological data obtained by remote sensing, and socioeconomic indicators is ideal for establishing, on a scientific basis, robust and objective decisions about phenomena that occur in cities.

In combination with widely automated methods of data processing and image analysis, urban remote sensing provides multiple options to support decision makers such as resource managers, planners, environmentalists, economists, ecologists and politicians with accurate and up-to-date geoinformation.

Keywords: Urban sprawl measurement, urban density index, Remote sensing and GIS 1.0 INTRODUCTION Accurate definition of urban sprawl although is debated, a general consensus is that urban sprawl is characterized by unplanned and uneven pattern of growth, driver by multitude
The normalized difference vegetation index ( NDVI) is a simple graphical indicator that can be used to analyze remote sensing measurements, typically, but not necessarily, from a space platform, and assess whether the target being observed contains live green vegetation or not.

The spatial pattern and dynamics of the urban sprawl of Kozhikode Metropolitan Area (KMA, Kerala, India) during the period from 1991 to 2018 using the integrated approach of remote sensing and GIS are attempted here. Index derived Built-up Index (IDBI) which is a thematic index-based index (combination of Normalized Difference Built-up Index (NDBI), Modified Normalized Difference Water Index (MNDWI) and Soil Adjusted Vegetation Index (SAVI)) is used for the rapid and automated extraction of
In order to appreciate the value of remotely sensed imagery for the analysis of urban places, We now apply the urban index to the study site of Cairo, Egypt.
