The use of high resolution satellite image for the classification of green open space area in Banda Aceh city, West Sumatra Indonesia

Population growth increasing every year can affect demand of land for residential, employment, and facilities, thus it may reduce areas of Green Open Space (RTH). Based on Indonesia Constitutions in UU No.26 year 2007 about Spatial Planning, proportion of RTH in urban areas is at least 30% of total city area. Remote sensing technology which based on satellite image can be used for monitoring land cover, especially for presence of green open space in urban areas. This study uses a high resolution satellite image which is digitally classified to identify land cover. Regarding an existing land use, it consists of eight classes; there are buildings, water bodies, roads, barelands, beaches, forests, gardens and rice fields. Image processing uses object oriented method using segmentation and merging so that pixels in the image become homogeneous as one entity for object representing each land cover class. The results of this study showed that green open space area consists of forest, gardens and rice fields classes with a total percentage are 32.86% of total city area. Thus, urban areas in Banda Aceh City can be categorized as a region; it has fulfilled proportion of green open space according Indonesia Constitutions in UU No.26 year 2007.
