Geography 481: Introduction to GIS
Review Sheet Two

Project 6: Editing Spatial Databases

• Geographic extent of boundary files often doesn't fit the needs of the project
• Source of attribute data is separate from boundary file
  
• Editing boundary files
  
• Select and save features
  
• Relational join of two attribute tables
  
• Join field

Project 7: Data Conversion

• Heads-up digitizing
• Working with GPS
• Adding X,Y coordinates (Events) from a table
• Reprojecting already projected data
• Geodatabases

Project 8: Address Geocoding

• Addresses contain limited spatial information which does not fit easily with other spatial data
• Address matching is based on street files that contain address range information
  
• Left-Right distinction
  
• From-To distinction
  
• Standard address fields
  
• Preparing a layer to make it address-matchable
  
• Matching addresses from an address list to a matchable street layer
  
• Rematching and tolerances
  
• Interactive matching
  
• Displaying addresses as point layers with attributes
  
• Displaying addresses as graphics with no attributes
   

Project 9: Digital Elevation Models

• Digital Elevation Model
  
• Spatial Analyst Extension and Grid Layers
  
• Elevation color gradients
  
• Hillshades
  
• Creating contours from a DEM
