_1.1.1 Types of Maps

1.1 Introduction to Maps

  • Overview of the importance and use of maps in geography.

1.1.1 Types of Maps

  • Types of maps: crucial for navigation and understanding geographical context.

    • Reference Maps: provide general information about location.

      • Political Maps: show states, countries, and capitals.

      • Physical Maps: depict natural features like mountains and rivers.

      • Road Maps: outline highways, streets, and transport routes.

    • Thematic Maps: focused on specific information about an area, revealing spatial aspects.

      • Types of Thematic Maps:

        • Choropleth Maps: use color/shade patterns to represent spatial data distribution.

        • Dot-Density Maps: each dot signifies a certain quantity of a characteristic.

        • Graduated/Proportional Symbol Maps: different symbol sizes indicate varying amounts of a variable.

        • Cartogram: areas are resized based on a specific variable, distorting actual size for visual emphasis.

        • Isoline Maps: connect points of equal value, useful for depicting temperature or elevation variations.

        • Topographic Maps: show elevation changes through textures and contour lines.

        • Flowline Maps: use variable-width lines to indicate traffic or movement flows.

1.1.2 Spatial Patterns and Relationships

  • Spatial Patterns on Maps:

    • Absolute Distance: exact measurement between two points.

    • Relative Distance: perceived distance based on various factors.

    • Clustering: grouping of spatial elements.

    • Dispersal: distribution of elements across an area.

    • Elevation: variations in land height represented on maps.

1.1.3 Map Evidence of Selectivity

  • Maps are selective in the information they present; projections may distort:

    • Shape

    • Area

    • Distance

    • Direction

1.2 Learning Targets

  • Identify types and purposes of maps,

  • Recognize different spatial patterns and relationships,

  • Understand the implications of map selectivity and distortion.

1.3 Essential Question Perspective

  • Big Idea: How do geographers use maps to discover patterns and relationships?

  • Geographers analyze maps to interpret spatial dynamics, recognize trends, and understand geographical interconnections.

1.4 Check for Understanding

  • Prepare for a quiz on map types and their uses.

  • Complete types of maps assignment as revision.
