World temperature map — voronoi data relief wall art

Design story and technique This panel turns global mean annual air temperature into a modular voronoi relief: each tile carries the average annual air temperature for its area (CHELSA V2.1, 1981–2010, CC0) and is assigned one of six colour/height bands. The bands (rounded to whole degrees) are: Polar Cold below −7 °C; Boreal Cool −7 °C to 2 °C; Temperate 2 °C to 8 °C; Warm 8 °C to 17 °C; Hot 17 °C to 24 °C; Tropical Heat from 24 °C. Height represents temperature band, not elevation. Technique a…
