There are many things that we can learn from studying maps of the Inca Empire. Moreover, from these, we can see many of the advantages and disadvantages that the Inca had.
The Inca empire was located in a long strip north to south on the western side of South America. A challenge that the Inca faced was the rugged terrain of the area, including the Andes mountains, the coastline deserts and the jungle. This made travelling difficult. It also required great creativity when establishing settlements or farming.
An advantage of such a territory was the presence of minerals. Gold, silver, copper, tin, iron and emeralds are all common in the region, and were used by the Inca. Moreover, the difficulties in accessing the region made invasions unlikely. The jungles and deserts also acted as natural barriers protecting them from enemies.
