Seems like not too many posters on here actually know what a mud map is. Imagine you land at farmer Brown's spread (the size of which is
larger than some European countries) not all of it contiguous, with the intention of spraying his crops. He wants THAT paddock of a few thousand acres sprayed, the one with some trees in it but not the one next door to it and also the next three big paddocks the power lines cross but not the one he just has just sown but the one he finished sowing the day before. You're lookin' at him and he's lookin' at you and he thinks you've got it until you start dribblin' out the side of your mouth and he gets the picture and starts to draw random lines in the mud with his gumboot because, these flyboys, they need everything drawn out for them. Mud maps: once upon a time that was about as good as it got. Get it?
As for mudmap apps... what'll they think of next? Moving map displays?
