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.

19. An assignment of geographic coordinates to locations.






20. 1. E - Ellipsoid dimensions. 2. D - Datum origin. 3. A - Angular alignment.






21. Connect & travel between landmarks by moving thru space.






22. Preserve Direction






23. Digital Elevation Model






24. The reverse of each other.






25. Regulary spaced sample of points representing a surface.






26. 3 levels of _______:1. Conceptual - definitions - attributes. 2. Logical Model - formalize definitions & measures. 3. Digital Model - define & describe features.






27. To avoid corrupt data!






28. Title - legend or key - grid system - distance scale - direction and compass rose






29. Defined by NOIR NOIR N-Nominal - qualitive data. O-Ordinal - order or ranking. I-Interval - numeric scale - arbitrary units. R - Ratio - fixed origin - continuous scale.






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






31. 7 Spatial Res: 30m Temporal Res: 16 day Swath Width: 183km






32. 3 topological concepts: 1. Connectivity - arcs connect to each other at nodes. 2._______ - arcs that connect to surround an area define a polygon. 3. Contiguity - arcs have direction & left & right sides.






33. Consists of F & E: 1. Features. 2. Entities.






34. 2 ______: 1. Unique ID. 2. Type Code. 3 Spatial Components PLP 1. Point. 2. Line/arc. 3. Polygon/area.

36. Description by name: ex London






37. Preserve Shape






38. 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.






39. Points - Polygons - Lines






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






41. 2 reasons why Topology matters: 1. Error detection. 2. ___________.






42. Where 2 lines/arcs intersect - an endpoint - or a point along a line.






43. The 5 key concepts in Geography & GIS (LDDSN) 1. Location. 2. _________. 3. Distance. 4. Space. 5. Navigation.






44. Uses coordinates (X -Y) to represent spatial features. Scale matters involve what Polygons<>points. Polygons<>lines.






45. The study of place names - origins - history & meanings.






46. Classes based on natural groupings through examination of histogram (good: minimizes differences bad: data range uneven)
