GIS-based Accessibility Analysis Using Suitable Landfor Public Parksin Larkana City Pakistan

Land-use plays an important role in social, cultural and physical development of human beings. A
variety of recreational activities creates conducive living environment for humans. Accessibility is significant
for land-use planning and use of suitable land for development. Uncontrolled expansion and unauthorized
development has created serious urban environmental problems due to urban facilities extension. This fact
affects the social behavior and physical development of residents. The aim of this study is to get a better urban
environmental benefits and accessibility to parks by the inhabitants of the Larkana city. In finding the suitable
land, geographic information system was adopted. Weighted model was integrated in GIS by using Analytical
Hierarchy Process (AHP) in finding the suitable land. Based on suitability map, the Euclidean-allocation model
was applied to determine the accessibility using GIS spatial analysis function of the ArcGIS software. The
results of this study revealed that it is not enough only finding suitable land for allocation of facilities, whilst
neglecting how these facilities should be accessed. Therefore, GIS spatial analysis technique is the viable
method to analyze service area’s parks accessibility facilities
