@inquiline It is nice! I like working with my ignorance, especially when it involves making interesting pictures and revealing meaning inside a mess. I happen to have a grad student at the moment who needs GIS technique (or a LOT of manual paperwork and calculation) to answer his research questions. I inherited him from a previous advisor who did not tell him this so it's been hard going for both of us. But fun for me, because I am tinkering and learning and making pictures.
