Visualizing Forest Ecosystems: Eco-Informatics Project

Explore how visualizing forest data helps understand trends, communicate with the public, and reveal patterns in a 3D world. This project processes LTER Reference Stands data to calculate heights, integrate GIS data, and address DEM concerns using Visual C++ and OpenGL. Future work aims to enhance the user interface and incorporate texturing. Acknowledgments go out to collaborators and funders. Access the demo for a closer look.

  1. Visualization of a Forest System Jennifer Hill 2007 Eco-Informatics Summer Institute Oregon State University

  2. Into this: The Goal Turn 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. Image from the Forest Visualization Project: http://silvis.forest.wisc.edu/visualization/ecoFir_Spruce.asp Future Work • Improve the user interface • Process more data • Include texturing

  7. Acknowledgments • To Eugene Zhang and Don Henshaw for their help and mentorship, • to Howard Bruner and Theresa Valentine for their help in acquiring data, • to the organizers of the EISI program, • to the National Science Foundation for their generous funding, • and to the people at HJ Andrews Experimental Forest, Thank you for this terrific summer experience!
