The goal of this assignment was to be familiarized with network analysis in ArcGIS. The objectives to be fulfilled was to learn to load features into Network Analysis window, calculate a route for trucks carrying sand, find the closest facility and best route to that facility, build a model that would calculate the closest facility, and find the cost incurred by each county,
Methods
To create a network analysis system I had to add the streets network data to ArcMap. The Network Analyst Extension was turned on after streets were added. If the streets were added after the extension would not have worked. I added all the geocoded mines from our previous exercise and queried out all mines that were rail loading locations as well. These mines were then merged together with the rail_terminals2 from the Ex 7 folder. Next was to load all the mines as stops with the Network Analyst. Next was to run a closest facility layer with the stops as facilities and the mines as incidents. I had to edit all the mines that were irrelevant to the situation. The next step was to build a model that would run similar to the closest facility this is shown below.
Results
The mines were found using Network Analyst and Model Builder.
Conclusions
The Network Analyst tool ran very smoothly and efficiently.
