the underscore and type your answer, followed by placing an underline on the answer text.

14-1 Why is GIS considered an enabling technology?

14-2 What is the most common GIS application?

14-3 Considering all of the GIS systems in use today, what type of GIS system is the
     most common?

14-4 Describe the three types of spatial queries.

14-5 List four GIS applications.

14-6 List three disciplines that provide techniques used by GIS.


Part II
Type your answer on the line below the question or item.

14-1 What happens to the data if it is converted from a raster format to a vector
     format?

14-2 What is the term that determines the conversion of vector data to raster data?

14-3 Describe how a raster GIS stores data. Give three examples of the type of
     features where the raster format works best.

14-4 Describe two advantages of a vector GIS. Give three examples of the type of
     features where the vector format works best.

14-5 List two advantages of a well-designed GIS interface.

14-6 Fill in the blanks. ______________ ________________ permits synthesis and
     data display in new and creative ways, using spatial and attribute queries.

14-7 Fill in the blank. A _________________ relates spatial data to attribute data.

14-8 What is the type of analysis that topology permits?

14-9 Give four examples of spatial data used on a regular basis by civil engineers.
