  1. Best Location For Amusement Park Geography 4050 Dr. Peterson Fall ‘03

  2. Project Outline • General Location • Obtaining the Data • The National Map Viewer • Nebraska Data Clearinghouse • Working the Data • Modifying Data • Spatial Analyst • Layout

  3. General Location • Populated Areas • Eastern Nebraska • Omaha • Lincoln • Available Transportation • I-80 Appeal • Half Way Between Omaha and Lincoln… • Mahoney State Park Area • Omaha Pull

  4. Finding the Data

  5. Obtaining the Data • National Map Viewers - http://nationalmap.usgs.gov • Four USGS Interactive Map Sites • The New National Map Viewer • Seamless Data Distribution System Viewer • Multiple Dataset Downloads • Seamless Data Viewer • 1/3” National Elevation Dataset (NED) • Land Use (1992) • National Map Viewer • State and County Boundaries • Roads • Cities • Hydrology • Downloads are Shapefiles

  6. National Map Viewers - http://nationalmap.usgs.gov

  7. Obtaining the Data cont’ • Nebraska Natural Resources Data Clearinghouse • Search by Category • Only Nebraska Data • Downloaded Sets • Detailed Road File (U.S Census TIGER) • Sarpy Co. Land Use • Arc Export Format

  8. Working the Data

  9. Modifying the Data • Export all .e00 extensions • Modifying Projections • Projection Wizard • Albert’s Equal Area Conic

  10. Modifying Data • Roads • Creating I-80 • Creating Exit 432 shapefile • Landuse

  11. Spatial Analyst • Hillshade • Obtains the hypothetical illumination of a surface • Uses the Digital Elevation Model (DEM) • Adds 3-D appearance when set transparent

  12. Spatial Analyst • Slope • Calculates the maximum rate of change between each cell • Uses the DEM • Green (Level) to Red (Steep) • The Flatter the Better

  13. Spatial Analyst • Viewshed • The cells in a raster that can be seen from one or more observation points or lines • Uses the Triangulation Irregular Network (TIN) • I-80 • Most of park should be seen • Attendance draw • Advertisement

  14. Spatial Analysis • Platte River Viewshed • Illustrates where Platte can be seen • River needs to be visible from the park • Green areas are visible

  15. Spatial Analyst • Cost Weighted • Finds the least accumulative cost from each cell to the nearest, cheapest source • Distance from I-80 • Cost was determined by elevation

  16. Spatial Analyst Landuse Viewshed Slope Cost • Reclassifying Data • Landuse – Forest, Pasture, Crops, Urban • Viewshed – Must be seen from Interstate • Slope - Flatter (Green) the better • Cost from I-80 – Less cost the better

  17. Spatial Analyst • Raster Calculator • Platte View 40% • I-80 View 20% • Slope 20% • I-80 Cost 15% • Landuse 5%

  18. Best Locations #3 #3 #2 #1 #1 #2

  19. Narrowing the Options • Location #1 • Flat • Great I-80 View • FEMA Flood Plain • Location #2 • Close to a Exit • Good I-80 View • Too Much Slope

  20. Narrowing the Options • Location #3 • Great I-80 • Close to Exit • Close to a Town • 20ft above floodplain
