The idea pitch reminds me of the Antique Atlas mod from Minecraft. It was made to substitute the traditionally mini map with its mob radar, massive discovery range, and instant access. The Atlas is supposed to be crafted with metals, easier in Minecraft but we can make a cheap early version called a map but doesn't show where you are on the map, unremovable waypoint markings, and has a limited map size. The higher tier made with leather makes a map book with unlimited range and removable waypoints. The last version, an Atlas or Cartographer's Journal, can be made combining some metal tool like a compass that shows where you are, shows coords, and has a larger discovery size, maybe add a share waypoint or map info feature with other Atlases. The only issue is I don't know if its possible to code a larger discovery radius based on elevation tiers. The maps can also have more detailed drawings/terrain the better it is.
Would also be cool to add a Cartographer class that has cheaper costs, starts with a map, or maybe a massive discovery radius bonus. https://www.curseforge.com/minecraft/mc-mods/antique-atlas
