Development of an Index for Assessment of Urban Green Spacesat City Level

Urban green spaces (UGS) are one of the indispensable elements for design and development of cities. UGS are considered as “lung” of cities as well as one of the elements reflecting the quality of life. The aim of this research is to develop Weighted Urban Green Space Index (WUGSI) for assessment of city wide UGS based on multi criteria analysis of Chandigarh city. The percentage of green, type of green and proximity to green are selected as parameters to study weighted urban green space index. All these parameters were derived from IRS P6 LISS IV data and IRS P6 LISS 4 + Cartosat-1 fused product. NDVI and Object based classification method is used to obtain different layers and then is analyzed using multi criteria analysis to derive the modified green index. The final result shows the distribution of green space in study area consisted of very high quality green, high quality green, moderate quality green and low quality green. The assessment of UGS was carried out sector wise and it was found that developed index is quite useful for assessment of UGS and can be used to identify the planning
