    5. Summarize attributes of objects within a region

    6. What is the best route?

    7. Show all of the objects satisfying the criteria

    8. Use of relationship between objects

    C. CHARACTERISTICS OF QUERY MODE

    User training

    D. PRODUCT MODE

    EXAM AND DISCUSSION QUESTIONS

    1. Describe the differences between query and product mode interaction with GIS. Which mode would you select in constructing a GIS for a state department of transportation?

    2. Discuss the use of product and query modes in accessing (a) phone directory information, (b) airline flight information, (c) TV program guides.

    3. How will geographical access to records most affect people's lives in the coming decade?

    4. What do you anticipate will be the level of production of 1:100,000 quad sheets by the US Geological Survey in the year 2010 - higher, lower than today or zero?
