Mod: Xaero's World Map
Link: https://www.curseforge.com/min…/mc-mods/xaeros-world-map
Description:
Xaero's World Map is a mod adds to the game a full-screen world map, which displays all the chunks that have been discovered. Its functionality is very limited (e.g. it doesn't even have such a basic feature as waypoints unless you install Xaero's Minimap as well), so for full functionality, it is recommended to also install Xaero's Minimap from the same mod developer (xaero96).
VERY IMPORTANT NOTE:
Xaero's World Map is a mod that works on BOTH sides — client-side and server-side as well. Naturally, when the mod is installed on the client side only, it has even more limited functionality, but still works well. People may not know about the server-side functionality, as it is a relatively new thing that was introduced in version 1.10.0 (source: https://chocolateminecraft.com/update.php?mod_id=2), quote:

+ Added the first server side feature. Installing this mod on the server side (in addition to client) will now make world map confirmation automatic and reliable.
