Which of the following best describes the difference between the DB2 Spatial Extender and the DB2 Geodetic Extender?

  1. The DB2 Spatial Extender uses a latitude-longitude coordinate system; the DB2 Geodetic Extender uses a planar, x- and y-coordinate system

  2. The DB2 Geodetic Extender is used to describe points, lines, and polygons; the DB2 Spatial Extender is used to find area, endpoints, and intersects

  3. The DB2 Spatial Extender treats the world as a flat map; the DB2 Geodetic Extender treats the world as a round globe

  4. The DB2 Geodetic Extender can be used to manage information like the locations of office buildings or the size of a flood zone; the DB2 Spatial Extender can be used for calculations and visualizations in disciplines like military command/control and asset

C Correct answer
Explanation

The DB2 Spatial Extender uses a planar coordinate system treating the earth as a flat map with x-y coordinates, suitable for small-scale applications. The DB2 Geodetic Extender uses a spherical coordinate system treating the earth as a round globe with latitude-longitude, essential for accurate long-distance and global calculations. Option A reverses this distinction, while options B and D describe overlapping capabilities of both extenders.
