Satellite Remote Sensing for Planning New Urban Environment. Spatio-Temporal Analysis of Urban Ecology in Karachi, Pakistan by using Remote Sensing and Geographic Information System

      Аннотация: Urbanization is a splendid perspective for the development in country and generates revenue in economy. Urban system has been increased due to population and has started exploiting ecosystems, they are now diversely driving nature from the semi-natural habitat to wastelands, parks human forced isotopes with their associated species. A new system of ecology has arose in urban areas named as 'urban ecology'. Main purpose of this study is to indicate the threats to natural environment of Karachi city. This research comes up with the temporal analysis of transition of urban ecology from year 2000 to 2016, Karachi is considered as the highest economy in Pakistan as it has sea port, industries, mills business center and fisheries but this race has compromised peace and health of city meanwhile, citizens have experienced climatic variation in last two decades. Satellite Remote Sensing (SRS) is the most inexpensive and effective means of extracting information and analyzing facts, moreover, SRS techniques provides high resolution images with multi-spectral data and useful information with a glimpse. Major findings of this study were followed by multiple algorithm analysis.
