4 Finding the Data

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

8 Working the Data

9 Modifying the Data Export all.e00 extensions Export all.e00 extensions Modifying Projections Modifying Projections Projection Wizard Projection Wizard Alberts Equal Area Conic Alberts Equal Area Conic

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

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

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

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

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

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

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