GIS: Geographic Information Systems

Subject : it-skills
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

18. LN 1. L - Level Surfaces. 2. N - NAVD88.






19. A data classification method that divides a set of attribute values into groups that contain an equal range of values






20. The 4 types of ___________:SADD. 1. S - Shape: Conformal. 2. A - Area: Variant. 3. D - Direction: Preserved. 4. D - Distance: Variant.






21. A reference system (geographic coordinates)






22. Application Programming Interfaces (increases access like my maps on google).






23. GIS is ________ - spatial analysis & dependent on the computer.






24. Digital Elevation Model






25. Fixed entitites - Can only take a specific value (Ex. number of students in a class - anything that is counted and not measured)






26. Smoothing & Shape abstraction.






27. Connectivity: ___________. 3 elements 1. Nodes & vertices define the shape of the arc. 2. Arcs have a from-node (or starting node) & a to-node (or ending-node). 3. Arcs only join at nodes.






28. Lines that connect points of equal value.






29. HAL - H-Human nature. A-Arbitrary/socially constructed. L-Loss of info (hiding variance within a class or group).






30. Shift in delivery (eg - require user interaction).






31. Can not be made from other colors






32. A Complete frame






33. Symbol on a map used to show direction






34. The nature of relationships & connectivity between them.
