I am trying to detect some sea level rise/fall for a specific region, from Landsat imagery.
I went through the recommended methods of identifying water/land (MNDWI, AWEI, Bandratio 5/2, etc.).
Now I am at the point where I need an accurate vectorized coastline. I tried with Geomatica Lineament extractor, but somehow I wasn't happy with the results.I have Geomatica 2013, ENVI 5.3 and ArcGIS 10.2.
