Data-Driven Cartography
Definition
Data-Driven Cartography refers to the design and creation of maps where visual elements—like color, size, and symbol shape—are dynamically driven by underlying spatial data. This approach allows cartographers and analysts to automatically produce multiple map outputs or interactive maps that change with updated data. It relies on rules, expressions, or attribute fields to control styling and map layout, ensuring consistency, scalability, and efficiency in cartographic production.
Application
In GIS, data-driven cartography is used to automate map series, thematic maps, and dashboard visualizations. Election boards use it to generate precinct maps for different regions. Real estate platforms color-code listings by price or area. Public health agencies create epidemic heatmaps with real-time data feeds. ArcGIS uses tools like Data-Driven Pages or Arcade expressions, while QGIS supports rule-based rendering and atlas generation.
