Webb30 sep. 2024 · The shoreline changes were statistically measured using three techniques, namely; Linear Regression Rate, End Point Rate and Net Shoreline Movement. For the automatic coastline extraction, different methods were applied, but among them most suitable techniques is the canny edge algorithm technique, which gives the accurate result. WebbThe delineation of shoreline polygons can have a variety of practical applications, from shipping and navigation to change detection and mapping coastal erosion. Often shoreline shapefiles are created using a semi-automated method combining automated boundary extraction and manual interpretation.
WebbTo extract based on a polygon feature that contains multiple disconnected parts, use the Extract By Mask tool. The center of the cell is used to determine whether a cell is inside or outside a polygon. If the center is within the arcs of the polygon, the cell is considered fully inside, even if portions of the cell fall outside the polygon.
