What's this? Nothing in particular, really. I just like showing off screenshots that make it look I'm smart! Hehe. It's like the guy who is, um, 'lacking', who buys a big-flashy-expensive car, in order to make up for his, um, perceived 'inadequacy'.

But seriously, all crude-jokes aside, this is just an in-progress piece of software I'm writing for work. What you're seeing is a map. I need to make an algorithm that will give me a line that's offset on the left or right side of any given line. (This offset line will represent a guardrail.) What you see here is an intermediary step in creating the offset lines with a bunch of extra labels for debug purposes.
