  7. How does the data set describe geographic features?


    Internal feature number. (Source: ESRI)

    Sequential unique whole numbers that are automatically generated.

    Scales of mapsheets (Source: Boone County GIS Department)

    12001 inch on the map equals 1200 inches, or 100 feet, on the ground.
    24001 inch on the map equals 2400 inches, or 200 feet, on the ground.
    48001 inch on the map equals 4800 inches, or 400 feet, on the ground.
