I'm working with Sentinel 2 data in python. Anyone with experience or insight about OpenEO for accessing and processing the data? I've used the eo-learn package with SentinelHub before, but seems it's not actively developed anymore. There seems to be some push for OpenEO, but not sure if I should migrate or not.

How much does landform position matter for vegetation dynamics across Calgary?

I explored how ΔNDVI (2025-2024) varies across geomorphon classes (summit, ridge, slope, hollow, valley, etc.) using a large spatial dataset (~194k observations).

A few key points from the analysis:
• Non-parametric Kruskal–Wallis test shows statistically significant differences between geomorphons
• However, the effect size is moderate (ε² ≈ 0.04)
• Distributions strongly overlap — landform position matters, but it is not a deterministic driver
• Median ΔNDVI tends to be higher in lower landscape positions (hollows, footslopes, valleys), consistent with moisture and accumulation controls
