The study analyzed changes in land use along the INCHEON coast using Landsat images and GIS tools. By classifying land cover over four years, the researchers were able to effectively manage and detect changes in the area. Specifically, they used ArcView to identify various land cover changes and easily search for past changes in specific regions. This research helps in understanding how the land is being used and how it is changing over time, which is crucial for efficient land management and future development planning.
