3D Terrain Modeling and Geovisualization

How elevation data and digital tools turn flat maps into interactive, three-dimensional representations of landscape, from raw terrain datasets to immersive, web-based, and dashboard-driven visualization platforms.

60-Second Review

Express review

A condensed, point-by-point summary of the module, for reviewing right before a test or exam.

  1. Digital Elevation Models and Terrain Data. Global elevation datasets like SRTM, ASTER GDEM, and LiDAR underpin all modern terrain modeling.
  2. Contour Lines and Topographic Map Reading. Contour lines connect equal-elevation points, following strict conventions refined since the 18th century.
  3. 3D Globe Visualization Platforms. From Keyhole EarthViewer to CesiumJS, browser-based globes made planetary terrain data instantly explorable.
  4. Hillshading and Relief Representation. Hillshading simulates illuminated terrain from a virtual sun to make elevation instantly readable.
  5. Virtual Reality and Immersive Geovisualization. Consumer VR headsets let users walk through planetary terrain, though its cognitive benefits remain debated.
  6. Terrain Modeling for Flood and Slope Analysis. DEM-derived flow paths and slope calculations underpin flood maps and landslide hazard assessment.
  7. Data Visualization Design for Spatial Stories. Narrative map design borrows from Tufte, ColorBrewer, and formal story-genre research to make data legible.
  8. Interactive Dashboards and Public Geospatial Tools. Web mapping libraries and dashboard platforms turned live geospatial data into public, real-time tools.

This module continues after "Historical Maps and the Evolution of Cartography" in the syllabus. If you haven't reviewed it yet, it may help set the context.
