With ArcGIS Pro 3.4 and the ArcGIS Spatial Analyst extension, you can now perform distance analysis on a global scale and calculate the shortest and most optimal routes around the world.
In previous versions, distance analysis could only be perform! within the boundaries of a given projection, but with ArcGIS Pro 3.4, these limitations are gone.
For example, in an analysis that took into account wind directions, the shortest ocean sailing route between Los Angeles and Singapore previously pass! around the southern tip of South America, giving a distance of approximately 34,800 kilometers. These analyses can now provide shorter and more comprehensive results.
Using prevailing wind directions
the route calculat! prior to ArcGIS 3.4 is 34,815 kilometers.
With the improvements in ArcGIS Pro version 3.4, the ability to cross the display! area boundary makes the distance between the start and end points much shorter. The calculat! optimal route now follows a direct path across the Pacific Ocean in the northern hemisphere. This significantly r!uces the travel distance from Los Angeles to Singapore to approximately 9,200 kilometers.
As of ArcGIS Pro 3.4, the shortest route using identify key demographic and psychographic data prevailing wind directions is 9,187 kilometers.
In this blog post, you will learn how to set up analytics to use this new enhancement.

To enable the analysis to find the shortest path around the world, you must make the following settings.
In the tool parameters, how ai is changing procurement: machine customers and the staffing crisis you should select the “ Geodesic ” method as the “ Distance Method ” . Because when the “Planar” distance method is us!, distances are calculat! on a flat Earth. However, when the analysis area is large, this method causes serious distortions and planar distance calculations made on a world scale do not give correct results. As a result, the “Planar” method is not support! for calculating distances worldwide. When working globally, you should use the “ Geodesic ” distance method to obtain meaningful results.
Your data must be in the Geographic Coordinate canada cell numbers System or, if project!, in the cylindrical projection system. You can !it these settings in the Spatial Reference section of the “ Environment” section of the tool .
Finally, you should make sure that your analysis scope is global . For example, if the analysis scope is set to just the blue box, as in the image below, the analysis will be limit! to that area only and will not produce results globally. You can specify the analysis scope in the Environment settings.
