Thanks! Do you work with or have you studied statistical measurements etc? I had to take a unit in undergrad; anything above what I would call basic stats is not exactly my strongest forte, heck I had to look up IDW to properly grasp it haha. I get a sense that Ohio is not going to be the pinnacle of food reviews, as it'd be a shame if the maps are then poorly/innaccurately made as a result. Still, something pretty to look at I guess. Also dig the XKCD - it may be a joke, but they say there's a little truth behind every joke ;D
Well, I just followed a course on geographical information systems, where I've learned how to make spatial analyses and derive maps from them. IDW was one of the used spatial analytic methods, I wasn't really expecting people to know it. The map is pretty but I just get irrationally angry when people make shitty maps. Just like incorrect kerning. So irritating, I have to correct it.
GIS is something I've wanted to look into, and could probably wrap my head around a lot more easily. Completely understand when you see something done poorly and want to correct it, it shows you're passionate about something! Hopefully this video will give you a good laugh, even if the maps are purposefully bad!
