  1. Why I Hate PowerPoint Also, the Impact of Class Definition on Landscape Metrics Used in FRAGSTATS

  2. The Details • Consolidate Classes from Lab 1 • Apply the same metrics to data from the same year (2001). • Observe results • Interpret results

  3. Original Classes • Following Slides Contain a List of the Original Classes. • More than 30 classes.

  4. Consolidation • ArcView condition (“con”) command. • All Urban Classes  1 Developed Class. • All Upland Forest Classes  1 Class. • Wetland Forest Classes  1 Class. • Some Classes not combined (pasture, fresh/salt water marsh, water, bare soil).

  5. 30+ Classes Down to 12 Classes

  6. What Are the Impacts? VS

  7. Original (Landscape)

  8. Modified (Landscape)

  9. PD Conclusions • Combined only shows slight increased in PD • Original  Class 112 increases the most while Class 113 is has the highest total PD. • Loss of detail, information.

  10. PLAND Conclusions • Combining classes increases PLAND vs classes that were not combined. • Graph two only shows increased trend in the developed class. • Detail is lost.

  11. COHESION Conclusions • Graph two only shows a slight increase in cohesion for Class 1. • In Graph one: 111 decreases, 112 increases, 113 decreases, and 114 decreases in 1984 then increases by 1995. • Detail.

  12. Conclusions • Impact on Landscape metrics was straight-forward. • Loss of detail in class-level metrics. • Change relationships between patches and classes.

  13. The End • Annoying Sound Effects! • Graphs! • Amazing Special Effects! • This is even better than a Duck Tales Episode!
