🌿 Greenness of Calgary Communities (Summer 2024)
📎 https://www.datastory.org.ua/greenness-of-calgary-communities-summer-2024/

Last year I published my first attempt to analyze the actual vegetation condition across Calgary and to build a data-driven ranking of its communities based on median summer NDVI. It was my very first experiment in assessing urban greenness at the neighbourhood scale — but the results turned out surprisingly insightful.
Some patterns were expected, while others revealed unexpectedly low vegetation density in places that looked green from the ground.

This exploration later grew into a much larger line of research on Calgary’s greenness, climate resilience, and spatial variability in vegetation health. You can find some results here with thematic hashtag #GreennessOfCalgary

If you're working on urban ecology, remote sensing, or land-cover analysis of Canadian cities — I’d be happy to exchange ideas.

🌳 Random Forests and Living Trees

English translation of my earlier article on applying satellite imagery and machine learning to map urban land cover.

What started as a local research project in Kryvyi Rih turned into something much larger — the results sparked a heated discussion among residents, officials, and industry representatives about the real condition of green buffers around large industrial sites.

The methodology developed during that work is still being used today — adapted for new environmental and urban projects.

🌿 NDVI change in Calgary’s Weaselhead Flats (2024 → 2025)

This map shows how vegetation in one of Calgary’s most diverse natural areas responded to the city’s unusually wet summer of 2025.
Greener shades mark zones where NDVI increased most strongly compared to 2024 — the same floodplain and forest patches that locals know for dense canopy recovery.

Even modest year-to-year shifts in temperature and rainfall leave clear spatial traces in NDVI — a reminder of how sensitive urban ecosystems are to climate variability, and how well open-data satellite products can capture it.

🛰 Data and processing: Sentinel-2 + R + QGIS

🌿 Calgary’s vegetation — satellite comparison (2024 → 2025)

Median NDVI maps from mid-May to mid-September show a clear difference between the two seasons.

In 2025, NDVI values are noticeably higher — vegetation stayed greener and denser for longer.
The wetter summer had a strong effect on canopy productivity across most Calgary communities, especially in parkland and tree-covered zones.

🌿 Calgary Greenness Dynamics (2024–2025)

Mapping ΔNDVI between the summers of 2024 and 2025 shows how Calgary’s communities changed in their vegetation cover.

🟢 Some areas became noticeably greener this year — likely due to the wetter and milder summer.
🔴 Others show slight declines, possibly linked to construction, soil dryness, or limited tree canopy recovery.

These patterns reveal how different parts of the city respond to seasonal variability — and where future urban greening might have the most impact.

🌿 Where Calgary Got Greener — and Where It Didn’t?

A quick look at how Calgary’s residential communities changed in greenness (NDVI) between 2024 and 2025.

🟢 Some neighbourhoods show a clear recovery of vegetation — probably thanks to a wetter, milder summer, better soil moisture, or local greening efforts.
🔴 Others stayed stagnant or even lost NDVI — maybe new construction, dry soils, or sparse vegetation played a role.

The bar chart shows Top-5 and Bottom-5 communities by NDVI change. It’s fascinating how uneven the “greening pulse” can be within one city.

📊 Based on Sentinel-2 data, mid-May – mid-September, processed in R.
