The right order is Cartography -> Navigational Compass -> Photography -> Internet.
Cartography - The first examples of maps used in Cartography dates back to the human pre-history. The oldest recorded route was found in Anatolia and was dated 6100-6300 BC, showing buildings and a volcano.
Navigational Compass - The first known compass was made with Lodestone, a black magnetized iron ore, during the 12th century. Chinese, European and Arab mariners used a different mechanism to make the magnetic phenomenon possible, but eventually, the lodestone was used to magnetize a needle that was floated on a small piece of wood in a small container of water.
Photography - The modern photography was established during the 19th century and was only used in a consistent manner by geographers by the end of that century.
Internet - The most recent milestone was the internet that came after the development of electronic computers in the 1950s.
