I need to create a network dataset for generating service areas based on Kilometres and Travel time.
I am using ArcMap10.5, Educational licence. I have downloaded two shapefiles for two countries from
Then, I used Merge tool and output was a feature class. So, I exported it to Single shapefile. I created a network dataset and for "Length" attribute, I chose "Shape" as "Value" in "Elevators" window.
When I create service areas, they are not correctly generated.
Do I have to do anything with the shapefile before creating network datasets?
