What technological advancements have mapmakers develop maps faster and more accurately?

Satellites and remotes sensing equipment are the technological advancements that have helped mapmakers develop maps faster and more accurately.

Remote sensing can be defined as discovering and monitoring the physical characteristics of an area. This can be done by measuring its reflected and emitted radiation at a distance from the targeted area. Remote sensing instruments can be grouped into two primary types, which are active and passive.

Active sensors make available their own source of energy to illuminate the objects they observe while passive sensors discover natural energy.
