I am trying to calculate hospital service area in Harris county in Texas. The total number of hospitals is 127 in harris county in Texas. There is not any problems when I try to calculate service area using overlapping, but when I change it into non-overlapping, there is problem' empty geometry information'.  I have tried to create a new network, but still have this problem. Please help me, I really appreciate it.
