Looking for help on locating the Z_max and the Z_min for over 2,000 routes. I have used the Add Surface Information Tool and have the information embedded within the route. What I need to do is show a point for the MAX and MIN location along each route. I have generated points for all the routes using the Feature Vertices to Points and adding the Z value to them. I am having a problem quickly pulling out the Min/Max for each route. Is there an easy way to select the routeID and the min & Max for each?
