What is space and how do we study it? Crash Course Geography #3

Share

Summary

Geographers study events in space, contextualizing places and human-environment interactions. This video explains four broad categories of space study: containers, topological, socially constructed, and individually perceived, demonstrating how they help us understand our world, with examples like mapping Antarctica and crowdsourcing maps for disaster relief in Haiti.

Highlights

Introduction to Geographic Space
00:00:06

Geographers study events in space to understand locations and human-environment interactions. Space can be measured, defined, and understood through relationships between places. This episode will explore different ways to discuss and study space.

Space as a Container
00:01:36

The simplest way to think about space is as a container. This helps answer "what is where?" by measuring and locating physical features, borders, or boundaries using tools like coordinate reference systems and GPS, which pinpoint locations using satellites.

Topological Space and Spatial Relationships
00:02:43

Once locations are known, we can understand their spatial relationships. Topological space measures and analyzes how features are arranged and connected. Spatial analysis, a blend of geography and math, identifies patterns and relationships using imaging technology, statistics, and geometry.

Remote Sensing: Studying Space from Afar
00:03:30

Remote sensing allows us to study space without physical contact, using satellites, airplanes, or drones to record reflected energy. This method has been crucial for mapping difficult-to-access areas like Antarctica, helping define boundaries and analyze relationships such as glacier movement and crevasse locations.

Socially Constructed Space
00:05:25

Socially constructed spaces are those given meaning by communities, like a coffee shop or a festival. These can be physical or virtual, and they become sites for social, political, or economic activity, creating a 'place' with shared meaning.

Individually Perceived Space
00:06:17

Individually perceived space incorporates the idea of place, recognizing how an individual's perception of a space can vary or change over time. This includes personal mental maps or historical understandings of how a space was used.

Case Study: Haiti Earthquake and Crowdsourced Mapping
00:07:03

Following the 2010 Haiti earthquake, a lack of maps hindered relief efforts. Crowdsourced mapping via OpenStreetMap allowed volunteers worldwide to digitize aerial and satellite images, creating essential maps that helped aid workers find routes, identify trapped people, and navigate the devastated areas effectively.

The Power of Community Mapping
00:08:31

Since 2010, communities globally have continued to use OpenStreetMap to digitize their local areas, adding meaning to maps with details like critical gathering places, hospitals, and businesses. This allows for up-to-date information, crucial for disaster relief, disease spread monitoring, and identifying safe areas. Anyone can contribute to creating valuable geographic data.

Conclusion: The Importance of Space in Our Lives
00:09:05

Understanding space through various lenses is integral to our lives. Geographers formalize the process of interpreting spatial data from various sources to create digital maps, allowing us to navigate, understand, and communicate the meaning of different spaces, ultimately helping us better comprehend the world.

Acknowledgement of Indigenous Lands
00:09:35

A final note acknowledges that many modern geopolitical maps and place names do not reflect the Indigenous or Aboriginal peoples' languages and their traditional relationships with the land. Viewers are encouraged to learn about the history of their local areas through resources like native-land.ca.
