  1. 5. may include the physical characteristics of a place, such as boundaries of a neighborhood, or the attributes of a place, such as a neighborhood's perceived unsafe areas.
  2. 8. A device or system that detects surface features on the earth by bouncing radio waves off them and measuring the energy reflected back.
  3. 9. To test for, detect, and correct errors in a computer program or component.
  4. 11. A collection of states representing the changes that have occurred over time in a versioned geodatabase.
  5. 12. In geoprocessing, data put into the system for processing, usually specified by a path in a dialog box, script, or at the command line.
  6. 14. The height or vertical elevation of a point above a reference surface.
  7. 15. data Data classified relative to a fixed zero point on a linear scale. Mathematical operations can be used on these values with predictable and meaningful results.
  8. 17. A brass or bronze disk, set in a concrete base or similarly permanent structure, inscribed with a mark showing its elevation above or below an adopted vertical datum.
  9. 19. A diagram or abstract map in which geographical areas are distorted proportionally to the value of an attribute.
