Senior Project - InVisable

This project was a three phased project. The first phase involved investigating methods of interpolating 2D and 3D randomly spaced data onto 2D and 3D uniform grids and the design and development of a C library for using some of these methods. An emphasis was placed on choosing interpolation methods that provided mechanisms for estimating errors and providing qualitative information about the accuracy of the output grid. The second phase of the project was to build an application using the interpolation library that allowed users, through an X Windows Graphical User Interface, to interactively select data files, select and configure interpolation methods, and finally produce an output grid file, using the standard Network Common Data Format (netCDF). This application also displayed qualitative information about the results of the interpolation, allowing users to choose an interpolation method that best approximates their data. The third phase was to develop with NCAR Graphics a utility, functioning as a UNIX command with command line options, capable of reading and displaying the gridded data, the random data and the error in the approximation.
