Just a quick post about my setup.
Softwares for plotting a grid are usually very good for regular latitude-longitude grids, like NCL or the Basemap package for Python. They can also managed unstructured grids with interpolation. However, it is usually impossible or very slow to draw an non-structured grid without interpolating data.
I wanted to get into Perl, and this is an excellent occasion for that. We want to modify the tags of all our mp3 files. Tedious to do by hand, so we need some script-fu.
