Data_Set_History: 1. Each county's coverages for the features roads, hydrography, railways and
county boundaries were projected from the State Plane coordinate system (using the zone or
FIPS Zone Code as described in the source coverage) to UTM Zone 14. Nebraska coverages
were projected from NAD27 to NAD83 (Kansas coverages were in NAD83). NOTE: The
western edge of Dundy county extends approx. 500 ft. into UTM Zone 13. Because the area in
question was so small, projection adjustments were not made. Data in this region will not be
accurate.
2. Polygon topology was built for the county boundary coverages and arc topology for the
roads, hydro and rail coverages.
3. Each of the 4 features was appended into a single coverage covering all the counties using
the `poly' and `all' options for the county boundaries coverage and the `arc' and `all' options
for the remaining 3 coverages. Polygon topology for the counties coverage was reconstructed
using `clean'.
4. An item titled `cnty_name' was added to the counties coverage and filled with the county
names.
5. Coverages were exported using the `none' option for no compression.
