Drought is a dynamic spatial process, not a static event.
This 2018 U.S. drought map visualizes intensity, frequency, and movement patterns using hexagonal aggregation and flow-based cartography. The strongest concentration appears across the Southwest and Southern Plains, highlighting both severity and persistence.
Tool: ArcGIS Pro (hexagon grid, hotspot analysis, advanced symbology).
Shoutout: John Nelson for the tutorial that inspired the cartographic workflow.
Data: NDMC, USDA, NOAA, USGS.
