Senior Project - RAVEN


Advanced Scientific Visualization Software for Meteorological Radar Data

Senior Project: 1991-1992
Michelle Dodge, Steven Epstein, Devin Hooker and Troy Sandblom

Modern meteorological radar systems can scan the full three-dimensional structure of complex storms and storm systems using high resolution (one degree beam) antennas. While software existed to view the data scan by scan, little software was available to examine the full three-dimensional structure of the storm as a whole. This project developed easy-to-use interactive visualization software for scientists to use in examining full 3D volumes of meteorological radar data.

The basic feature of the software is an ability to select and display arbitrary 2D "slices" from the scanned volume, according to pre-defined color tables. These slices are typically either vertical cuts or horizontal slices through a 3D Cartesian data grid. The scientist is able to zoom and pan within the data grid, and can easily modify the color tables in use. The software has the capability to maintain and display multiple independent variables for each grid point. The project was implemented with an object-oriented approach in C++, using the X Window System and the Interviews graphical user interface toolkit.
