I have built an interest in the mnemonics and used it to remember list of items (countries/capitals, tour de france winners, numbers of PI, some phone numbers, …).
In my professional live I work at TomTom (we build digital maps) and I actually gave a course about these mnemonic techniques to a group of engineers looking to learn new stuff in our office. However, when looking a bit more in the topic it seems it’s hard to find a good way to memorize a map. E.g., mnemonics are great to remember a list of countries, but I am looking to memorize the place of those countries on a map.
I even would want to pull it further: how to memorize any location-based information like:
Places on earth
Positions of objects on an image
Hence, I am on a quest to find good techniques to memorize location-based information.
