The image below shows the Distance Accumulation raster output layer creat! by running the Distance Accumulation tool. Each location in this result has a value representing the distance to the Port of Los Angeles via the most convenient (or least cost) route .
Distance Accumulation Raster Result
The image below shows the Back Direction raster layer creat! by running the Distance Accumulation tool. Back Direction rasters contain values ranging from 0 to 360, and these values indicate the directions towards the source, following the least cost route .

For example, you should run the Optimal Path As Line tool using the Distance Accumulation and Back Direction rasters obtain! in the next step .
Optimal Path As Line allows you to generate the least cost routes as a line using analysis data generat! with tools such as Distance Accumulation or Cost Distance .
Input Raster or Feature Destinations: Raster or vector data specifying destinations.
Destination Field: If the arrival data contains more than one destination, this is the field that will be us! to create a separate route for each. For example: If there is a different ID for each port, you can use this field.
Input Distance Accumulation Raster: Distance streamline your team’s workflow Accumulation raster creat! with the Distance Accumulation tool. This raster contains the cost of each cell to reach the source.
Input Back Direction Raster or Flow Direction Raster: Back Direction raster creat! with the Distance Accumulation tool. This raster indicates the least-cost direction (0–360°) of each cell to the source and is necessary to follow the correct
Output Optimal Path As Line: The name of the route layer in line format to be creat!.
Path Type: This parameter defines how routes will be creat!. It offers 3 options.
Each Cell : Draws a separate route for each destination cell
Each Zone : Cells with the same value are implementation of a transparency and monitoring mechanism consider! as a zone, and a single route is creat! for each zone.
Best Single : Gives only the best route among all destinations.
Create Network Paths: This is an advanc! option that allows routes to behave like a network when working with multiple destinations. When this parameter is enabl!, the tool creates a network structure by taking into account the connections between destinations instead of drawing only one- canada cell numbers way lines between destinations and sources. In short, routes are creat! as a network of routes, passing through the most suitable connection points instead of going directly to the sources.
In the example scenario in this blog post, the vehicle parameters are set as shown in the image below.
Parameters of the Optimal Path As Line tool, which is the second step for calculating the optimal sailing route
On the map below you can see the most convenient routes from the Port of Los Angeles to several ports around the world. Some of these most convenient routes go across the Pacific Ocean, while others go around Cape Horn at the tip of South America.
