4. Advantages of GIS The need to collect the geometry of the roadway sections is eliminated. Less labor intensive Ability to Customize to Fit Parameters Expanded for other Applications After the initial entree Does not take two people three days to collect data and enter it. You can adjust the results based on the budget or amount of materials. Can be expanded to include other highway applications such as guard rail, signs, culverts, bridges, base layers, etc. After the initial entree Does not take two people three days to collect data and enter it.
