💻 I took several completely independent datasets and "pitted" them against each other. One of the results is shown in this chart: the more "concrete" (roads, buildings, parking lots) my machine learning model identified in a community, the higher the surface temperature recorded by the thermal sensor.

🔥 The result: Data from different sources confirm one another. The difference in surface temperature between "green" and "concrete" residential areas averages 8–10°C throughout the summer. On certain days, this gap is likely even wider.

📉 This chart shows only established residential communities. If industrial zones were included, the trend would be even more dramatic. While modeling errors certainly exist, the overall physical pattern is undeniable.

🌳 I am finalizing a tool that allows for a rapid and accurate assessment of the green infrastructure in any Calgary community. This isn't just "green color" on a map—my algorithm recognizes the differences in the quality and structure of the urban environment.

What we can quantify right now:
🔹 Lawn (Grasses, low shrubs): Open spaces that tend to dry out and heat up quickly during summer.
🔹 Park (Sparse Canopy): Scattered groups of trees in parks and private yards.
🔹 Forest (Dense Canopy): The "lungs" of a neighborhood, characterized by closed canopies and thick undergrowth. These areas provide vital protection against urban heat.

❗ Why does this matter?
Using Inglewood as an example (see the chart), we can see that "dense forest" covers only about 5% of the area. This is a critical indicator of the territory's climate resilience.
