IELTS reading passage – Mapping
Mapping
These days, a mapmaker’s vision is not limited by what the eye can see. The crow’s nest of the sailing ship, the mountain top, and the airplane have given way to new orbital altitudes as the perspective of mapmaking. Radar can see through dense jungle cover and has created the first maps of the mountains on Venus. Radar works by sending microwave radio waves to a surface and collecting photos of its shapes and textures. Additionally, charts of the seafloor are created using a mix of sonar and radar, which first places a large portion of Earth on a map. According to the opinion of Joel Morrison who is the chief of geography at the U.S. Bureau of the Census, “Suddenly it’s a totally different universe for us.” Even in five years, “our future as mapmakers is dubious.”
The basement of the Congress Library in Washington, D.C. houses the biggest collection of maps in the world. Up to 4.6 million map sheets and 63,000 atlases make up the collection, which also contains stunning bound collections of intricate maps from the Dutch cartography’s heyday. In the reading room, academics use magnifying lenses to study historic maps while donning thin cotton gloves to safeguard the delicate sheets. People are analyzing the most recent maps while seated at their computers across the room. Computers can store information about people, places, and surroundings — the elements of maps — thanks to their enormous memories. Information is then presented on screens practically immediately in the proper geographic context, and with the touch of a button, a printout of the map is produced.
The first significant step in scientific mapping was the measurement of the spherical Earth. The Greek astronomer Eratosthenes, a student at the renowned Alexandrian Library in Egypt in the third century BC, was the first to accomplish this. His estimate of 25,200 miles for the circumference of the Earth was amazingly accurate. We currently know the longitudinal circumference to be 24,860 miles.
Ptolemy, an astronomer and geographer who lived in the second century AD, developed a system for arranging maps using latitude and longitude grids by building on the theories of his forebears. The reason for the width of current time zones is that meridians are typically spaced at intervals of 15 degrees and parallels are frequently spaced at intervals of 10 to 20 degrees. Ptolemy’s suggestion to cartographers to produce scale-based maps is another one of his legacies. On modern maps, distance is shown as a percentage or ratio of the actual distance. However, Ptolemy’s mapmakers lacked the geographic expertise necessary to uphold his scientific standards. Maps are not accurate representations of reality, even today, when surveyors can reach accuracy down to inches and satellites can plot probable missile targets down to feet.
But just as the compass enhanced navigation and increased demand for practical charts, the printing press, which was developed in the 15th century, freed monks from producing maps, which had previously tended to represent religion rather than geography. Ocean-going ships ushered in an era of exploration by expanding the scope of what could and needed to be mapped and arousing a thirst for knowledge about the wider globe.
Mapmakers in the fifteenth century gradually replaced theology with knowledge of distant locales as recorded by travelling merchants like Marco Polo, who were inspired by the rediscovered Ptolemy, whose work had been conserved by Arabs after the destruction of the Alexandrian Library in AD 931.
The most famous shipbuilder of the 16th century, Gerhardus Mercator, devised a method for positioning meridians and parallels that allowed navigators to draw straight lines between two sites and maintain a consistent compass course between them. The “Greenland issue” was established by this distortion formula on his world map from 1569. One of the numerous issues with trying to depict a round world on a flat piece of paper is that Greenland still appears to be as big as South America on some modern standard maps. But because the Mercator projection was so valuable, sailors continued to choose it.
With the accomplishments of the Cassini family, including the father, son, grandson, and great-grandson, scientific mapping of the area came into its own. The system’s creator, Jean-Dominique, who was born in Italy, developed a sophisticated way to calculate longitude based on observation of Jupiter’s moons in the late 17th century. Surveyors were able to create an accurate map of France using this method. His great-grandson published their renowned Cassini map in 1793, during the French Revolution, while the family continued to explore the French countryside. Even while it might not have had the same visual appeal as earlier maps, this one served as a social and geographic map model, displaying highways, rivers, canals, cities, abbeys, vineyards, lakes, and even windmills. By accomplishing this feat, France became the first nation to be entirely mapped using scientific techniques.
Since then, maps have advanced greatly. Today’s surveyors hardly ever enter the field unconnected to navigation satellite systems. Surveyors are increasingly using the satellite system built and still run by the US Defense Department, whose hand-held receivers are the most well-known of the new mapping technologies. It can be used by regular hikers, sailors, and explorers to provide location information. They can be purchased in simplified civilian versions for a few hundred dollars, and they serve as the brains of some cars’ electronic map displays. However, regardless of how far away “there” may be, cartography’s goal has always been to convey a feeling of where “here” is with respect to that location.
