A classic book is "Cross Country Navigation" by Neil Phillips and Rod Phillips (1989), aimed at the sport of Rogaining. It emphasises navigation by using the surrounding landscape and its features, rather than trying to impose a rigid coordinate system on the landscape. In this way, one works with the landscape, continually adapting to follow the (quickest) path of least effort, rather than trying to blast through on a preconceived "best" course. The philosophy is the same, whether one is inside or outside a city. It's sort of like Parkour on a large scale. https://www.worldcat.org/title/cross-country-navigation/oclc/27609102 https://www.worldcat.org/title/cross-country-navigation/oclc...
