SITE SUITABILITY ANALYSIS FOR A GREENFIELD AIRPORT IN KOLKATA USING GIS AND REMOTE SENSING

摘要

Geographic Information Systems (GIS) and Remote Sensing are widely recognized as a valuable tool for capturing, storing, manipulating, analysing, managing and displaying all types of geographical data. Due to the complex nature of airport planning modalities, the potential of GIS applications in resolving several issues on airports is increasingly acknowledged by many. In this paper, we have discussed some of the potential benefits of ArcGIS applications in airport site selection. Using site suitability analysis an attempt has been made by the authors to find the most suitable and feasible sites for the construction of a green field airport in Kolkata. West Bengal. India. Here, the study takes into consideration the most import and likely factors such as slope, drive-time buffer, land use/land cover information, restricted zones and the prevailing meteorological conditions. Accordingly, different candidate sites for the new airport have been analyzed. The study also highlights the role of such a multi-criteria approach performed within the step by step decision-making process concerning the site selection for recommending five different sites for the plausible development of a new airport at Kolkata.
