    EXAM AND DISCUSSION QUESTIONS

    1. Describe the "linear", "choropleth" and "precision" views of the world used in this unit.

    2. Why are there so few vector-based GISs designed for small computers (e.g. PC)?

    3. Describe the three-corner scheme used in this unit, and explain the nature of each corner or pole. Why is it not possible to develop a system which optimizes all three measures of performance?

    4. Compare several different GIS products across the range of characteristics listed in this unit. Make some conclusions about the applications each of the products would be best suited for.
