Special Topics in GIS (GIS5935): Lab 3

The goal for this week's lab was to show the percentage difference of accuracy between two road networks of Jackson County, Oregon. To get the results of how many polygons were complete depending on Street dataset and the TIGER Roads dataset, I exported each polygon grid into its own separate shapefile. Once all of the polygons were separated, I clipped the two datasets to the each of the polygon by using the batch option on the Clip tool. After the datasets were clipped to the polygon, I recalculated the geometry of the data to kilometers and used the ‘Statistics’ option to gather the sum of all of the polyline features’ length.
