Essential elements in cartography: what are they and how are they studied?
Cartography is the science that studies the representation and creation of maps. To achieve this, it's important to understand the essential elements that make up cartography and how they are studied.
Essential elements in cartography include cartographic projections, scale, subtitles, Geographical coordinates, landmarks e symbology. Each of these elements plays a fundamental role in creating accurate and informative maps.
Cartographic projections, for example, are flat representations of the Earth's surface that aim to minimize distortions. Studying the different projections and understanding their characteristics is essential for creating accurate maps.
Scale is another crucial element in cartography, as it determines the relationship between distances on the map and actual distances on the Earth's surface. Understanding how scale works is essential to correctly interpreting the information presented on a map.
Legends are used to explain the symbols and colors on the map, facilitating the understanding of the information presented. Studying how legends are created and interpreted is essential to ensuring the map's clarity.
Geographic coordinates are used to determine the precise location of a point on the Earth's surface. Understanding how coordinates are represented and how they are used in cartography is crucial to creating accurate maps.
Landmarks are used to aid orientation and identify specific locations on a map. Studying how landmarks are chosen and represented is essential to ensuring the map's accuracy and usefulness.
Finally, symbology is used to represent different elements on the map, such as rivers, roads, cities, and borders. Understanding the symbology used in cartography is essential to correctly interpreting the information presented on the map.
In short, the essential elements of cartography play a fundamental role in creating accurate and informative maps. Studying each of these elements and understanding how they are used is essential to producing quality maps.
Types of cartography: discover the three main forms of geographic representation.
Cartography is the science that studies the representation of the Earth on maps. It uses various techniques and methods to represent geographic space accurately and comprehensibly. There are several types of cartography, but we will highlight the three main forms of geographic representation:
Thematic Cartography: This type of cartography focuses on representing specific information about a given topic, such as population distribution, a region's vegetation, or the geology of a territory. It is widely used in environmental studies, urban planning, and socioeconomic analyses.
Topographic Cartography: Topographic cartography is dedicated to representing the relief and shapes of the Earth's surface. It uses contour lines, altitudes, and geographic coordinates to show the terrain's elevations and depressions. It is essential for activities such as navigation, civil engineering, and infrastructure planning.
Geodetic Cartography: Geodetic cartography is concerned with accurately representing the Earth's shape, taking into account the planet's curvature. It uses techniques such as geodesy to determine geographic coordinates and the Earth's shape. It is essential for creating high-precision maps and for global positioning systems such as GPS.
In short, cartography is an essential science for understanding and exploring geographic space. It allows us to visualize and interpret information about our planet, supporting various areas of knowledge and everyday practice.
What does cartography study? Main characteristics
A mapping studies mapping representing different areas of the Earth, or even other planets, as the data allows.
This work has become easier thanks to technological advances. For centuries, cartography required considerable art and imagination, as vast unexplored lands remained.
According to the International Cartographic Association, cartography is also responsible for the study of existing maps, both from a scientific and artistic point of view.
The word cartography comes from Greek. It is formed by the ancient khartēs words (map) and graphin (writing), which perfectly define its function.
Human beings have always tried to create these documents, which help them better understand their lands and those they attempt to explore.
Tasks
Cartography refers to the study of the physical characteristics of a territory in order to capture them on a map.
To do this, cartographers need to have knowledge of various subjects, such as geography, geometry, statistics and, of course, the ability to reflect all of this in a document.
Because the planet is spherical, professionals in this field must use various tools to obtain the measurements of this sphere on a flat model.
They should also keep in mind that the poles are flattened, so the map's scale is appropriate. The mathematical ratio between reality and what is drawn on the plane is called scale.
History
The beginnings
There is no clear consensus on which map was the first in existence. It seems clear that the first one must have been small, representing only the lands surrounding human populations.
A wall painting is known to be a map of the Turkish city of Çatalhöyük, dating from the seventh millennium BC.
It is considered that it was the Greeks who introduced the scientific method in map making.
Authors like Herodotus and Eratosthenes (who measured the Earth's surface) produced maps, but it was Ptolemy who applied mathematical rules. In fact, his world maps were used until the Renaissance.
From the Middle Ages to the present
Centuries later, during the Middle Ages, the maps created often introduced religious elements.
For example, in many of these, Jerusalem appeared as the center of the planet. Obviously, only Europe, Asia, and Africa appeared—the three continents known to date.
The printing press and the discovery of America revolutionized this art. Crowds of explorers began exploring unknown territories to include on maps.
However, such a level of precision has never been achieved. The use of aircraft, satellites, radar, and other techniques has made the entire Earth's surface and part of the marina perfectly mapped.
Map Types
– Political maps
They reflect the different countries, cities and other types of administrative divisions.
– physical maps
They are the ones that show the natural elements of each area.
– Climate maps
These are the ones that indicate the different climatic zones.
– topographic maps
In addition to showing geographical features, these maps provide data about those features. For example, they can indicate the altitude of mountains, hills, or valleys using contour lines.
– geological maps
These maps show the different minerals in each area, volcanoes and faults.
