Abstract
The purpose of this article is to choose the best possible places for radio astronomical observations sites using Multi-Criteria Decision Analysis (MCDA) coordinatedusing Geographical Information Systems (GIS). The study was carried out in the Peninsular of Malaysia, which is favourable for astronomical site observatory facilities with its appropriate climate properties and weather environments. Eleven factors were resolved, divided into two categories; geographical and anthropogenic. This parameter was estimated using Analytical Hierarchy Process technique and the weights of criteria layers were determined. Therefore, the most suitable areas were located widely in eastern and southern part of Peninsular Malaysia. This finding offers a sturdy, accurate, cost and time effective procedure for preliminary site selection for radio astronomical observatory.
