This example simulation demonstrates the effects of land-use decisions from the years 1986-1991 on the western North Carolina (Macon County) landscape for 100 years beyond 1991. After the simulation has completed, the GRASS monitor containing both the original land-cover and the final transition land-cover maps is displayed (see Figure ). It is difficult to tell for certain from the final land-cover map how the amount of each landcover type has changed during the simulation. To analyze the result of the simulation, graphs of the statistics are displayed.
A Graphs window (see Figure ) is displayed after the simulation has completed in order to allow the user to observe trends in desired statistics. Several graphs are displayed in this example, including:

From the proportion of landscape graphs (see Figures and ), it can be observed that the proportion of unvegetated land cover increases from less than 1 percent to nearly 2 percent of the land being unvegetated in the year 2091. The proportion of the landscape covered by forest decreases by 1 percent in the 100 year simulation. The area of covertype graph (see Figure ) indicates that approximately 1000 hectares of landscape transitions to unvegetated landcover during the simulation.
