Urban park site selection at local scale by using geographic information system (GIS) and analytic hierarchy process (AHP)

The Significance of urban green space situates it among the five important urban uses. Site selection of public green spaces necessitates social requirements. This study aimed at optimal site selection of urban parks at local level in the City of Shahrood. The only option on the table to do so included integrating GIS with Overlaying. First, criteria were incorporated into GIS and new information layers were created, which in turn were employed in conjunction with the existing data to gain information such as conflicting uses (military, industrial) as well as wasteland situation. In so doing, statistics and maps with a scale of 1:10,000 were utilized. After overlaying, four sites were considered as alternatives. In the next step, the determinant criteria were weighted in AHP, and pair wise comparison was conducted in order to discover the optimal alternative to build a local scale park. The results reveal that Site 2 in Area 4 is the best alternative.
