The municipality of Itaqui is located in the region called the western border of the state of Rio Grande do Sul, which has some areas of preservation and leisure in the urban area, consisting of squares, parks, among others. The green areas are very important for the welfare and quality of life, so it is necessary to be aware of the importance of conservation of this heritage, since it promotes the balance between urbanized areas and the environment. In this sense, the main objective of this work is to perform an analysis of the indicators of green areas using tools of geotechnology for the city of Itaqui-RS. In order to carry out the study on green areas it is necessary to calculate the indicators of green areas, namely: the green area index (BTI) and the percentage of green areas (VAP), such indices were estimated for the 17 County. For this, the supervised classification method was used using satellite images as well as the comparison of the results with the NDVI classification, which were also used for the preparation of maps to visualize the results. In this context, this work showed satisfactory results regarding the use of the methods mentioned here.
