5.2.13 Advantages of the GIS method

• Potential for storing and accessing very large data set.

• Consolidates data from various sources for geographic analysis.

• Effectively performs multiple map overlays, incorporating logical and mathematical manipulations.

• Generates descriptive statistics regarding the distribution of spatial phenomena.

• Allows a number of different scenarios to be investigated quickly and effectively by varying input parameters for successive analysis runs.

• Can generate maps for output to hard copy as well as displaying map information on the computer screen.
