AP Human Geography Unit 1: Intro to Maps & Spatial Patterns

Map

  • A map is a two-dimensional model of the Earth's surface, or a portion of it.

What are the two purposes of maps?

  • Reference tools: show where something is found and how to get there.
  • Communication tools: depict the distribution of human activities and physical features.

Features

  • (From transcript) Roadmap to understanding maps and their uses; core concepts include the transformation of the Earth’s surface into a manageable representation.

Cartography

  • The science of map making.

Geospatial Technologies

  • Remote Sensing: The process of capturing images of Earth's surface from airborne platforms such as satellites or airplanes.
  • Global Positioning System (GPS): The system that accurately determines the precise position of something on Earth via satellites and receivers.
  • Geographic Information System (GIS): A computer system that analyzes and displays geographic data.

Layers

  • Layers are types of geographic data (e.g., countries, bodies of water, place names).

Mashups

  • The practice of combining layers on a map to create integrated representations of geographic information.

Data Types

  • Qualitative Data: Data associated with a humanistic approach to geography; describes qualities, characteristics, or attributes (non-numerical in nature).
  • Quantitative Data: Data associated with mathematical models and statistical techniques; numerical measurements and statistics.

Data collection and presentation (How data is collected and described)

  • How is it collected?
    • Via surveys, polls, questionnaires, interviews, observations, artifact analysis, etc.
  • What does it describe?
    • The phenomena or patterns under study; topics can be debated and interpreted.
  • How are findings presented?
    • Qualitative findings are often expressed narratively.
    • Quantitative findings are presented with statistical analysis.

Connections and implications

  • Geospatial technologies enable the capture, storage, analysis, and display of geographic data, supporting navigation, planning, and understanding spatial relationships.
  • The combination of layers and mashups allows for flexible, layered analyses of places and phenomena across scales.
  • Distinctions between qualitative and quantitative data guide research design, data collection methods, and presentation formats.

Real-world relevance

  • Maps and GIS inform city planning, disaster response, resource management, and environmental monitoring.
  • Remote sensing provides timely information about land use, vegetation health, and changes over time.
