Analisa Perubahan Garis Pantai Di Kabupaten Indramayu Menggunakan NDWI

Jurnal Perikanan Unram
Kabupaten Indramayu merupakan salah satu daerah di pesisir utara Pulau Jawa dengan panjang garis pantai ±140 km. Selama 15 tahun terakhir telah terjadi fenomena abrasi dan akresi di Kabupaten Indramayu, sehingga menyebabkan perubahan besar pada garis pantai. Oleh karena itu, perlu memanfaatkan teknologi penginderaan jauh untuk melakukan penelitian guna

Why NDWI threshold varies in delineating water body from multitemporal images?

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
Water body can be extracted from a satellite image with normalized difference water index (NDWI). It is commonly known that the index varies if extracting water body using multi-temporal images. This study selected 33 cloud-free scenes of MODerate-resolution Imaging Spectroradiometer (MODIS) data over the Poyang Lake region located in a subtropical ...
