The application of the Geographical Information System (GIS) extends beyond mapping and includes an analysis of attribute and geographical data, identification of behavioural patterns, and visualisation of positional analysis outcomes. The system provides accurate coordinates, enabling functions such as storage and retrieval, pattern search, and model creation in GIS applications. One widely adopted approach for land-use identification involves utilising GIS operations to establish databases and conduct analyses. Thus, this study utilises ArcGIS software tools to determine the suitability of land and optimal location for the development of community gardens in Shah Alam. Decision-making was based on multiple criteria, and to ensure accurate and comprehensive data, the researchers employed a qualitative method similar to expert interviews. Related government agencies and authorities, as well as experts, provided input through three separate expert interviews. Findings from the interviews highlighted the significance of land slope, elevation, land use, proximity to settlements, road accessibility, and water access as important considerations for site selection in urban gardening or community gardens. The study demonstrates the effectiveness of GIS methods in obtaining such results and recommends that future research focus on assessing the potential for sustainable development by leveraging GIS techniques.
