Hello Listserv,
I have point dataset of ship trips from one port to another. I want to calculate the shortest distance between each port pair over water. There are thousands of voyages, and 5,000 unique ports from all over the world. One of the approach I can use in ArcGIS is to run the Cost-Path tool having water/land as a cost raster to make a path only on water. But I assume that the Cost-Path approach would be little tedious for a large dataset. I wonder if anyone in this forum has a suggestion to calculate a shortest distance between two points having restricted path.
I will highly appreciate your feedback.
