Geography An Overview
Geography: An Overview
Introduction to Geography
- Geography is a broad field, and this lecture serves as part one of the introductory material for week one.
- Students are required to watch both parts (including "earth basics") entirely, as they will be tested on the content.
What is Geography?
- Many students have encountered geography in their K-12 education within history classes.
- Geography is often perceived as memorization and map-based knowledge; however, this is only partially true.
- While K-12 geography involves maps, geography at the university level is very different.
- This course will provide a taste of what geography truly is, but maps will still be used to some extent.
- The focus will not be on memorizing locations like the Rocky Mountains or African lakes.
- A specific definition of geography is not provided because the lecturer finds definitions too limiting.
- Geography stems from the ancient term "Geographia," meaning to write and study about Earth.
- The course will not focus on memorizing planetary features or map details.
Defining Geography Broadly
- Geography is a multidisciplinary field examining Earth's physical and human landscapes, and the relationship between them.
- It is divided into three main subfields:
- Physical Geography
- Human Geography
- Geospatial Technologies
- Geography majors receive training in all three subfields and specialize as they advance in education.
Physical Geography
- Focuses on physical landscapes, systems, processes, and changes over time.
- Draws from geology, climatology, oceanography, meteorology, biology, etc., to understand spatial distribution of features.
- This course is primarily about physical geography and includes a lab component for practical learning and application.
Human Geography
- Examines human landscapes and patterns over time.
- Interfaces with history, migration patterns, population demographics, urbanism, sociology, resources, and war.
- Looks at the human landscape superimposed over the physical landscape, studying patterns.
Geospatial Technologies
- Formerly the cartography portion of geography, now uses advanced computer software.
- Includes Geographic Information Systems (GIS).
- GIS is widely used in cities, utility companies, fire departments, crime analytics, real estate, census information, and the U.S. Government.
- Earning a GIS certificate is popular among geography majors due to its job prospects.
- GIS involves systems like ArcGIS, ArcMaps, made by Esri, a billion-dollar company.
- Students will see some ArcGIS maps in labs but will not build them themselves.
Mapping and Human Nature
- Maps are used in this course, including basic maps and Google Earth assignments.
- Humans have an innate desire to organize space around them.
- In ancient times, communal settings like nomadic tribes had organized layouts with central bonfire areas and separate structures for sleeping and storage.
- Even in camping, people organize campsites, considering privacy, flat ground, and safety.
- Humans organize space to make sense of it, even in personal spaces like rooms。
Mapping as an Extension of Organizing Space
- Mapping is an extension of the human desire to organize space.
- The Roman Empire used maps to understand and document borders, cities, infrastructure, and troop locations.
- Ancient Chinese maps and maps from the Muslim Golden Age of the Mediterranean also reflect this.
- Today's maps are more advanced, such as population cluster maps, transportation maps, and census data maps.
- Examples:
- Population cluster map of India, Iran, and Saudi Arabia
- Transportation cluster map of the Middle East
- U.S. Census Bureau maps showing states with the most divorcees at age 30
