Cartography and Technology
The development of the compass greatly helped mapmakers, because then they could be more precise in their map-making. The invention of the printing press really helped the uniformity of maps overall, because now map makers could make one map and they could create an exact duplicate over and over again until everyone had a map that looked exactly the same of the same area. It took out a lot of room for error.
The invention of the telescope and other devices like it allowed cartographers to use the sun at noon or the North Star and measure it, so they could figure out their own latitude. Today, we have GPS’s and range finders that allow people to make maps on the go.
In addition, commercial-quality maps are made on specialized computer software that helps map makers be extremely precise and accurate.
That’s a quick look at the development of maps throughout the years.
