Hi Gary, Thanks for your work I have been working to an interpolation plugin of point data (loaded in openjump as shape files) to a DTM raster. I used the code from s former ImageJ plugin ( https://imagej.nih.gov/ij/plugins/xyz2dem-importer.html) which was quite fast and very flexible. The interpolation plugin is a part of a larger openjump project to work with raster, like ArcGIS raster tools. The project is here: https://sourceforge.net/p/opensit/wiki/Geo%20Arbores%20Raster%20Tools/. Actually it works only with Openjump 1.xxx series (not openjump 2) but I am working to port it to newer openjump. For sure i will give a look to your code and reuse it Thank again Peppe
