Answer:
La Paz is a bit more densely populated than Lima, since the former has a population density slightly higher than this of latter.
Explanation:
In this case, we need to know the populations and occupied area of the city. By definition, population density is the ratio of the population of the city to the occupied area in the same location.
The required information is gathered below:
La Paz (Bolivia)
Population: 1.801 million (Metropolitan area)
Occupied area: 475 square kilometers.
Population density: 3792 inhabitants per square kilometer.
Lima (Perú)
Population: 9.674 million
Occupied area: 2672 square kilometers.
Population density: 3621 inhabitants per square kilometer.
In this case, La Paz is a bit more densely populated than Lima, since the former has a population density slightly higher than this of latter.

That system is also complemented by the cellular towers if you're using a cell phone.
Aerial photography is great, but it will not tell you where you are.
Remote sensing is to gather information from a distance, not relevant to the question here.
The Geographic Information Systems are information systems to give information about the land matched with precise GPS information, used in mining for example, but it's not able to tell you where you are, it's to tell where a gold deposit is however.
