Application of Simple Remote Sensing Techniques for the Detection and Extraction of Coastline-A Case Study of Diu Island, India

Tóm tắt:

Anumber of techniques have been applied for the detection and extraction of coastline all over the world by researchers. In this paper simple remote sensing techniques based on the spectral band ratios methods such as Normalized Difference Vegetation Index (NDVI) and Normalized Difference Water Index (NDWI) were applied to classify land water component from satellite images for automatically extracting coastline of Diu Island, India. NDVI and NDWI images were reclassified into binary image format to extract the coastline as a vector data. The accuracy of the extracted coastline from different band ratio methods was evaluated using standard map and Google Earth Image coastline boundaries
