2. The Goal Turn this: Into this:

3. Why visualize data?  Easier to understand  Reveals trends  Communicate with the public …It’s a three dimensional world! VS.

4. The Data Set  LTER Reference Stands Multiple years and locations Detail-rich  Data processing Calculate heights Integrate GIS data DEM concerns

5. The Program  Built with Visual C++ and OpenGL Over 850 lines of code!  Functions Navigation Year swapping Stand swapping Tree selection

6. Future Work  Improve the user interface  Process more data  Include texturing Image from the Forest Visualization Project: http://silvis.forest.wisc.edu/visualization/ecoFir_Spruce.asp
