“How Much Greener Is Calgary in 2025?”

Using Sentinel-2 data (~8.5M pixels), I calculated NDVI change (ΔNDVI) between the 2024 drought and the rainy 2025 season across all Calgary communities.

Clear spatial pattern:
• Strong rebound in mature tree neighborhoods
• Limited change in developing, impervious-heavy zones

Method: R (terra, tidyverse) + QGIS
Community boundaries: Open Calgary
