Is the subdiscipline of geography concerned with the construction of maps.

The correct answer is - Cartography.

Cartography is the sub-discipline of geography that as a main focus has the creation of maps (of various sizes) and globes. People have been developing cartography for over 2,000 years, and over time they managed to slowly improve it, both with the bigger knowledge of the world and with the advancements in technology. For most of the history of the cartography, the maps were made on hand, but in the past few decades it made a huge leap forward with the usage of computer programs, which is much quicker, easier, and more precise.
