This model can calculate the shift of two shoreline or coastline, rate and estimate the future position by End Point Rate equation (EPR). Input parameters Year be Simulate: Inform the year the EPR simulation will be run. Year of Oldest Line: Insert the year lof Oldest Line. Example: 1985. Baseline Left: Insert a baseline in left side of the line of shore/coastline. This baseline is a continuous parallel line and the two extremities need be a little more longer than the shoreline. This baseline can have more than one vertices point. Space between point / Error: This parameter select how will be the accuracy of result. A small number get better and more precise result, but the process turn very slow. Is recommended put 1/4 of the pixel size of the raster used to delimitated the shore/coastline. Example: A Landsat with 30m insert a 7.5 or 5. Year of Newest Line: Choose the year lof Newst Line. Example: 2019. Newest Line: Insert the newest shore/coastalline in shapefile format. Beach Angle: The Beach Angle parameter is a angle between 0 and 359 grades informing how be the angle of the graphical result. Baseline Right: Insert a baseline in Right side of the line of shore/coastline. This baseline is a continuous parallel line and the two extremities need be a little more longer than the shoreline. This baseline can have more than one vertices point. Oldest Line: Insert the more old shore/coastalline in shapefile format. Result Style Final: Set the Style of Result with .qml file. Result Style - Left: Set the Style of Result with .qml file. Result Style - Right: Set the Style of Result with .qml file. Leftside Result: This shapefile have a graphical result that top of prism shows the last position in future of shoreline. Rightside Result: This shapefile have a graphical result that top of prism shows the last position in future of shoreline. Points: This shapefile shows the space between points. This result is just to see if have some error in analysis. Newest Line: Shapefile with the distance between the position compare with baseline. Oldest Line: Shapefile with the distance between the position compare with baseline. Outputs Leftside Result: This shapefile have a graphical result that top of prism shows the last position in future of shoreline. Rightside Result: This shapefile have a graphical result that top of prism shows the last position in future of shoreline. Points: This shapefile shows the space between points. This result is just to see if have some error in analysis. Result: Shapefile with the distance between the position compare with baseline.
