Hi all, First of all, I would like to thank Gary for the help to solve an important issue in OpenJUMP. This project is the result of a collaborative work of many people coming from different experiences and using OpenJUMP for different purposes: work, teaching, research. Extending this collaboration with other people from other projects surely extends our knowledge and ability to improve both OpenJUMP projects and our vision of a collaborative project open to anyone. Thinking of that at the beginning OJ was considered a *good but only basic vector-oriented GIS software*, it is a good result that actually OJ is used in the University of Padua as basic software *to teach hydrology* *via raster analysis*, which usually requires a large capability to manage data and computation. The authors of these results are very good developers who contributed during the years, I just remember <in a strict alphabetical order> Alberto, Ede, Michael, Stefan and many others. I should thank all of them. And Gery for his collaboration.
