Green spaces analysis in residential development of Puchong, Petaling Jaya using Geographical Information System (GIS) / Farisha Addinni Mazlan and Nurfarzana Marsya Hamzah

Urbanisation poses a challenge to the distribution and accessibility of green spaces, which are critical for the sustainability of urban ecosystems. This study examines green space ratios in Puchong, Petaling Jaya, Selangor, within urban residential developments, in accordance with Malaysia’s National Urbanisation Policy and the Town and Country Planning Act 1976, which require at least 10% green space in residential zones. This study used an imagery taken from USGS website (Landsat 8). The image was processed with GIS techniques, such as image classification and image clipping to identify existing green spaces and locations with insufficient coverage, then compares the findings to regulatory requirements.
