I am currently using ArcGIS Pro (network analyst, OD cost matrix analysis) to calculate distances between a set of points A and a set of points B. Distances are calculated along my own road map, which I have in a shape-file. To do this, I first build a network data set in ArcMap, which I import in ArcGIS Pro prior to the distances calculations.
I am now trying to move my project from ArcGIS Pro to ArcGIS Online, and I wonder if it is possible to somehow create the network data set (that I need as input in the OD Cost matrix analysis) in ArcGIS Online? Or do I need to have this ready, and publish it to my ArcGIS Online account in order to perform the distance calculations?
