Hi all, thank you in advance for any help you could give me. I'm new here and may have posted this in the wrong place.
I am unclear about what network database templates are and how I can use them. I've done a little poking around on google and youtube about this topic, but I'm still unclear.
I am attempting to use arcpy with ArcGIS 10.7 to do a simple service area analysis--how far distance-wise through a road network is a place on the road network from any of the nearest of many facilities. However, the geographic scope of this effort is quite large and can be over entire countries--say all of Japan.
What I currently have the idea to do is create a network dataset on a smaller area in ArcMap, then use arcpy to make a template of the of this network data set using the CreateTemplateFromNetworkDataset tool.

I would then like to use that template to create a network dataset for the larger area using CreateNetworkDatasetFromTemplate.

Specifically for this effort, I would like to make a network dataset and create a template of it for the Japanese island of Shikoku. Then I would like to use this template to do the service area analysis mentioned above for all of Japan. Is this possible? The code seems to work but I don't understand what is happening under the hood and I'm worried I might be missing something.
I'd also like to know more about templates and schema's in general. For example, can I use the templates I create for this on Japan, on other countries? I know that part of a schema is the projected coordinate system. So as long as I determine that the projected coordinate system from the first template is suitable for the new area I want to do the service area analysis on, can I just use the same template? What else is or could be missing?
Thank you for any possible help!
