Summary: A prototype of a data visualization and decision support tool has been developed with the following features and capabilities:
- Built based on an open-source data mining tool. It has an open architecture design with which users can add their own visualization/data processing lug-ins.
- Supports 2-D visualization for geo-spatial data collected in the field. The 2-D images can be overlaid with Google earth. We have implemented this idea with the PAR data provided by UC Davis.
- Supports 3-D visualization for geo-spatial data collected in the field. The visualization is done through OpenGL, and users can perform on-the-fly rotations and zoom the 3-D image.
- Imports data in user-defined formats. We drafted a meta-data definition standard in XMI and sent out to other teams for discussion.
- Identify the position of tree using the young trees with simple geometry.
