ABSTRACT This article measures the distribution of green areas within the subdivisions of the municipality of Goiânia. It aims to verify if the regulation presented in Federal Law 6.766/1979, which regulates the Parcelamento do solo urbano, is being fulfilled regarding the reservation of at least 10% of the total subdivision for green and leisure areas. This is mainly an observation for a future scenario, there is an expectation of reducing the metric to 7.5%, to be provided in the draft law of the New Master Plan. To obtain the data, techniques of Digital Image Processing and information analyzis, with Geographic Information System, were applied. The results were surprising, because of the 1.089 subdivisions analyzed, 512 allotments, equivalent to 47.02% of the area, have coverage of green and leisure areas, less than 10%, thus, not complying with the current regulations provided in the legislation. For the new the 7.5% metric, this number reduces to 458, which may compromise the losses of 2.1 km² of these spaces.
