Presentation Transcript

  1. The Mighty and Dreaded Toolbox! • Take some time and get to know it

  2. Vector Analysis

  3. Generalization • ArcToolbox -> Data Management Tools -> Generalization -> …

  4. Generalization (100 meters) Original Generalized to 100 meters

  5. Generalization (1000 meters) Original Generalized to 1000 meters

  6. Geometric Calculations

  7. Polyline Geometry • Use an “Equidistant Projection”

  8. Polygon Geometry • Use an “Equal Area” Projection

  9. Centroid

  10. Making Centroid Point Layers • Add fields for X and Y • Use “Calculate Geometry” to add the X and Y coordinates of the centroid • Open the dbf in Excel • Save the dbf to a tab-delimited text file • Use “Tools -> Add X Y Data” to add the text file as points

  11. Buffering • Creates polygons around existing vector features • ArcToolbox -> Analysis -> Proximity -> Buffer

  12. Dissolving • ArcToolbox -> Data Management Tools -> Generalization -> Dissolve • Combines features based on a common attribute value ArcGIS Help

  13. Clip • ArcToolbox -> Analysis Tools -> Extract -> Clip • ArcToolbox -> Data Management Tools -> Raster -> Raster Processing -> Clip ArcGIS Help

  14. Intersection • ArcToolbox -> Analysis Tools -> Overlay -> Intersect • ArcToolbox -> Spatial Analysis Tools -> Local -> Combine ArcGIS Help

  15. Vector Processing • Perform math on attributes using “Field Calculator” • Query attributes to select desired features • Right click on layer -> Selection -> Create Layer from Selected Features • New Shapefile and Layer • Perform spatial analysis • Repeat
