I have a raster data where pixel value of each cell represents the potential minimum travel time across the cell in old world.
Now, I need to find the minimum travel time of some points from Addis Ababa (Ethiopia) in Arcmap. This needs to be the travel time on land (no seas or oceans). The raster data is missing values on seas and oceans.
In other words, I need the sum of pixel values on the route between a point and Addis Ababa, but only going on land.
Any suggestions on how to do this? Do you know any alternative methods to calculate migratory distance from Africa?
