 The goal of this assessment was to determine which project between the two shapefiles given had more complete data. First I clipped the centerlines and tiger shapefiles to the grid shapefile in order to break the roads up. Then I used the intersect tool to pair each clipped section with the grid that they were clipped to. I then used the tabulate intersection tool in order to calculate the length of each section of road in order to find out which one was more complete. I merged the two intersected layers and added the percent difference data that I solved by using the formula provided. Lastly, I joined the percent difference data with the merged layer and symbolized the map as a choropleth map.
