Other questions in this quiz

2. What is the relationship between the geoid and the ellipsoid?

  • The ellipsoid comprises the smoothed area of the geoid earth
  • Earth is made up of a smooth geoid and an elevated ellipsoid
  • Geoid includes smoothes topography on the top of an ellipsoid
  • Geoid includes the rough surface of the sphere of the geoid

3. How do you measure distance?

  • Distance= velocity x time
  • Distance= velocity/time
  • Distance= time - velocity
  • Distance= time + velocity

4. What is a benefit of raster data?

  • The resolution is not as clear as vector data and can make the data redundant
  • Can change the resolution to fit purpose of display
  • Mixed pixels are not as clear and hard to distinguish between
  • Redundancy of data by increasing the resolution which decrease topological error but increase volume of data

5. What is not a feature of primary spatial data?

  • Total stations can collect primary x,y and z coordinates relative to the spatial reference system
  • Sometimes collected without a spatial reference but you can allocate a spatial referencing system on top in order to conform
  • You do not need a spatial referencing system
  • GPS collection
