Lesson 3
TECHNOLOGICAL CHANGES
I Read and translate the following text:
In cartography, technology has continually changed in order to meet the demands of
new generations of mapmakers and map users. The first maps were manually constructed with
brushes and parchment and therefore varied in quality and were limited in distribution. The
advent of magnetic devices, such as the compass and much later magnetic storage devices,
allowed for the creation of far more accurate maps and the ability to store and manipulate
them digitally.
Advances in mechanical devices such as the printing press, quadrant and vernier
allowed for the mass production of maps and the ability to make accurate reproductions from
more accurate data. Optical technology, such as the telescope, sextant and other devices that
use telescopes, allowed for accurate surveying of land and the ability of mapmakers and
navigators to find their latitude by measuring angles to the North Star at night or the sun at
noon.
Advances in photochemical technology, such as the lithographic and photochemical
processes, have allowed for the creation of maps that have fine details, do not distort in shape
and resist moisture and wear. This also eliminated the need for engraving which further
shortened the time it takes to make and reproduce maps.
In the late 20th century and early 21st century advances in electronic technology led to
a new revolution in cartography. Specifically, computer hardware devices such as computer
screens, plotters, printers, scanners and analytic stereo plotters along with visualization, image
processing, spatial analysis and database software, have democratized and greatly expanded
the making of maps. The ability to superimpose spatially located variables onto existing maps
created new uses for maps and new industries to explore and exploit these potentials.
