I recently posted a new open-source software project that may be of interest to the
visitors at this forum, particularly those working in Java.
The Gridfour Project is an attempt to create and distribute software tools for
processing raster (grid) based data. Potential applications include geophysical,
scientific, and engineering data. Eventually, I hope the project will provide tools
for rendering, data compression, contouring, surface analysis, and so forth.
The first module written for the Gridfour project is a file-backed data store
that is intended to assist applications in building and managing collections
of raster data that are too large to be kept in memory. I also posted some B-Spline
interpolation utilities and am working on some rendering tools.
