One of the essential elements of landscape planning is the design of urban green areas which is important for community welfare. Data about green area in large cities can be collected from aerial survey or satellite imageries. Analysis can be applied using GIS to determine the relation between urban green area (UGA) per resident in the city when statistics of number of inhabitants in the city are known. The computed UGA per resident can then be compared with respect to standard or recommended values given by: World Health Organization (WHO) or by the United Nations (UN) or any other organization. Studying the distances that people need to walk to the nearest green area should also satisfy a certain limit. This paper is an attempt to outline some published research about finding out the UGA per capita in various world cities.
