Here is a quick tutorial video about planning a walk that sticks to the contour. A walk that follows the contour means you won't need to walk uphill and down dale much. I should feel like a pleasant stroll through the bush.

This little video tutorial shows how I apply contour mapping to planning a walk. I show you a local walk called the ring track. You see the mountain from the air, then we look at a map of the ring track. I show you a small error on google maps where the track is missing in one of the layers but not another layer. then we look at how the tracks sticks to the contour 320m above sea level. And I share with you the points at which it deviates from the contour.
After watching this video - please do the same to explore the contours of an area you have walked.
