Diagram

In cartography, a diagram is a simplified, schematic representation of geographic or spatial information, used to illustrate relationships, patterns, or structures that might be difficult to visualize through traditional maps. Diagrams in cartography often abstract spatial elements to emphasize specific features or data trends.

Basic

Introduction

Key Characteristics of Cartographic Diagrams:

  • More abstract than standard maps – Focuses on relationships rather than precise geographic accuracy.
  • Uses symbols, lines, and simplified shapes to convey information.
  • Enhances understanding of complex spatial concepts by eliminating unnecessary details.

Explanation

Types of Diagrams in Cartography:

  1. Flow Diagrams (Flow Maps)

    • Show movement patterns such as migration, transportation routes, or trade flows.
    • Example: A diagram illustrating global airline routes.
       

  2. Network Diagrams

    • Represent connectivity between locations (e.g., roads, utilities, subway systems).
    • Example: A transit map (like the London Underground map) simplifies geography for clarity.
       

  3. Cartographic Models & Schematics

    • Abstract representations of spatial relationships, like terrain generalization or population distribution.
    • Example: A topographic diagram showing elevation levels.
       

  4. Proportional Symbol Diagrams

    • Use scaled symbols to represent quantitative data over a geographic area.
    • Example: A bubble diagram showing city populations.
       

  5. Thematic Data Diagrams

    • Used in statistical cartography, such as bar or pie charts overlaid on a map.
    • Example: A diagram displaying GDP distribution across regions.
