Coastline Difference Measurement (CDM) Method

Abstract

Coastline Difference Measurement (CDM) Method is designed to provide a fast and practical way to obtain distance differences between 2 taut zonal coastlines. Comparison purposes could be considered as change detection to monitoring coastal zones or obtaining accuracies while studying coastline extraction methods. In this study CDM method is explained over a coastline extraction case. In this example case, CDM method is used to measure accuracy of the estimated coastline via Extra Trees (ET) machine learning model. Main advantages and limitations of the methods are explained.
