dc.description.abstract The increase inpopulation is in line with changes in land use area so that the need for built areas is increasing. In this study, satellite data will provide information about land use in Pontianak City. Land use is focused on built-up areas which includes five classifications, namely services and industry, education and offices, settlements, ricefields and green open space . The development of land use changes in an area can be analyzed by utilizing remote sensing data in theform of multi-temporal satellite images. According to (Petit et al. 2001) one way to find out quickly the land use change is by using remote sensing technology. Geographic Information System (GIS) is an information system that is designed to be able to work with data that has spatial/spatial references or geographical coordinates, the term in other words GIS is a data-based system that has a unique ability to handle data that has spatial references (spatial), with a set of work operations that work concurrently. From the 2008 land use map, the service and industrial area of 7.1 km2 is equivalent to 6.6%; education and office area of 3.6 km2 equivalent to 2.9%; a residential area of 26.8 km2 equivalent to 24.3%; rice fields area of 21.3 km2 equivalent to 19.7%, and green open space of 50.2 km.2 equivalent to 46.5%. The total area of Pontianak is about 109 km2. The total area of Pontianak, mainland and rivers, is 116 km2. Land use in 2021 shows that the condition of the residential built area has the largest area of 41.91 km2 equivalent to 38% and the smallest area is the service and industrial area of 7.7 km2 equivalent to 7% of the total area of Pontianak city, while other areas are education and office space is 15.13 km2 equivalent to 14%, ricefields are 18.14 km2 equivalent to 17% and green open space area is 26.57 km2 or 24%. Based on the study of land use changes in Pontianak City from 2008 to 2021, it shows that green open land and rice fields are decreasing. This is evidenced by the increase in the area of residential areas in the city of Pontianak and the service and industrial areas or trade areas. The area of green open space and ricefields has decreased in area. Validation is needed to determine the suitability between the interpretation results and the existing results. The validation results on the land use map produce an accuracy of 100%, so the research results can be used as basic information for further research. en_GB
