However, you could consider these options depending on the context:
* Non-cartographer: This is the most literal opposite, simply indicating someone who is not a cartographer.
* Someone who destroys maps: This is a very specific and extreme opposite, but it could be relevant in certain contexts.
* Someone who doesn't use maps: This could be someone who relies on other methods of navigation, like intuition or landmarks.
* Someone who misinterprets maps: This implies someone who uses maps but does not understand or follow them correctly.
Ultimately, the best antonym will depend on the specific context and the nuance you want to convey.
