Topics to be discussed Definition Importance History of cartography Modern cartography Essential cartographic processes.
Definition The International Cartographic Association defines cartography as the discipline dealing with the conception, production, dissemination and study of maps.
Textual Definitions
Formal Definitions Cartography is considered as the science of preparing all types of maps and charts and includes every operation from original survey to final printing of maps (United Nations 1949, cited in Freitag 1993). Cartography is the art, science and technology of making maps, together with their study as scientific documents and works of art (I.C.A in Meynen 1973). Cartography is the discipline dealing with the conception, production, dissemination and study of maps (I.C.A. in Anonymous 1992)
A History of Cartography –First Maps 6200BC - Catal-HyukMap –Wall Painting Assyria –map of Mesopotamia (2500 B.C.) on a clay tablet.(interpretation) 600BC -Babylonia –first map with world surrounded by the sea and heavenly bodies(interpretation) 6 th century B.C. -first Greek map ascribed to Anaximander–no details survive Plato –first to put earth as sphere- 400 BC Erasthosthenes-250BC-measures the Earth’s circumference accurately –concept of grids 450 BC -First Map in western literature: Herodotus
Value of Maps
Value of Maps As a way of recording and storing information Governments, businesses, and society as large must store large quantities of information about the environment and the location of natural resources, capital assets, and people. Included are plat, parcel, and cadastral maps to record property, maps of society's infrastructure or utilities for water, power, and telephone, and transportation, and census maps of population.
Value of Maps 2. As a means of analyzing locational distributions and spatial patterns Maps let us recognize spatial distributions and relationships and make it possible for us to visualize and hence conceptualize patterns and processes that operate through space. 3. As a method of presenting information and communicating findings Maps allow us to convey information and findings that are difficult to express verbally. Maps can also be used to convince and persuade, or even propagandize.
Importance of Cartography
Importance of Cartography Three Assumptions: Cartography is relevant Cartography is attractive Cartography is modern
Cartography is relevant Modern cartography is key to humankind. Without maps, we would be spatially blind. Knowledge about spatial relations and location of objects are most important for enabling economic development, for managing and administering land, for handling disasters and crisis situations, or simply to be able to make decisions on a personal scale on where and how to go to a particular place.
Cartography is attractive Maps and other cartographic products are attractive. Many people like to use maps; to play around with maps, for instance, on the Internet; or simply to look at them. We can witness a dramatic increase in the number of users and use of maps currently.

Cartography is modern! Maps can be seen as the perfect interface between a human user and big data.
Cartography is modern! New and innovative technologies have an important impact on what cartographers are doing. Maps can be derived automatically from geodata acquisition methods, smart models of geodata can be built, and a whole range of presentation forms is now available.
Cartographic Process
Cartographic Process
Four Main Cartographic Processes Collecting and selecting data for mapping Manipulating and generalizing the data, designing and constructing the map Reading or viewing the map Interpreting the information presented on the map

What are the basic kinds of maps?
Political Maps Political maps show how humans have impacted the landscape. For example, city names, roads, country borders, etc. are all part of political maps. A political map often uses colors to show the boundaries between states or countries.
Political Maps Political maps change frequently (physical maps change very, very slowly through geologic processes) and must be redrawn often. A political map of the world that is 50 years old is no longer accurate. Wars and ethnic conflict are two major causes political maps change.
Political Maps
Physical Maps Physical maps show what the surface of the Earth looks like. A physical map highlights Earth’s natural features, such as mountains and forests.
Physical maps do not contain man made features. For example, a physical map would be a map of what you would see if you were looking down on Earth from space. Physical Maps Notice you do not see country borders or city markings. These divisions are created by people. For example, there is no actual line dividing Texas from its bordering states.

Physical Maps There are different types of physical maps. Relief Maps – Show the difference in height between land Elevation Maps – Show the elevation, or height above sea level.

Map Review Think about a hiker. What kind of map would they need? A physical map. Why? They would need to know things like where mountains, forest, and rivers are.
Map Review I am planning a trip to New York. What kind of map would I most likely need? A political map Why? A political map would show me states and cities. This is information that I would likely need to know if going to New York.

THE OLDEST EXISTING MAP
THE OLDEST MAP Oldest existing map (6200 BCE)* Wall painting at Catal Huyuk (Turkey) Depict the town plan, with erupting volcano *Your textbook references a far younger map… Leopard pattern?
DISCLAIMER Ancient cartographic history is spotty Few ancient maps remain Many have been lost to time Many have been destroyed Clay is easily broken Paper and wood decompose and catch fire Bronze maps were often melted down
DISCLAIMER Many ancient maps have been “reconstructed” Reconstructions are suspect Many were reconstructed based upon manuscripts, which often included vague, or poetic language Many were copied graphically by medieval monks, who knew little of what they were copying
DISCLAIMER This presentation is far from complete How can thousands of years of cartography be summed up in a single lecture? Emphasis is given to groups of people and periods of time that the instructor is most familiar with I urge you to explore what I don’t cover here
BABYLONIAN MAPS

Ptolemy’s World Map
GREEK MAPS Ptolemy’s Projections (150 CE) A major cartographic breakthrough Conic Projection Resulted in far less areal and angular distortion than orthogonal grids used previously. With slight modifications, this projection is still in use today. Pseudoconic Projection Reduced distortion even further, but was more difficult to construct. Ptolemy recommended this second projection to all but the lazy .
