    EXAM AND DISCUSSION QUESTIONS

    1. Determine the status of LIS development in your own county/municipality. Is there an LIS, or are there plans to automate the land records system?

    2. The 1980 NRC report cited above recommended, amongst other things, that "Federal legislation should be proposed to authorize and fund a program to support the development of a multipurpose cadaster in all parts of the Nation". What factors might account for the fact that this recommendation has not yet been implemented?

    3. Discuss the significance of scale in a multipurpose cadaster. What is the minimum scale required to carry out each of the applications of an MPC described in this unit? What scale would you recommend for a cadastral base for your community?

    4. How do the contents of an LIS database differ from those of a) a CAD and b) a GIS database? What additional information must be stored if the LIS database is to function effectively?
