Unsupervised Anomaly Detection in Satellite Time Series: When AI Learns 'Normal'
How unsupervised methods flag change in a satellite time series without labelled training data — from the ±2σ rule to seasonal decomposition and isolation forests — and how to watch an area for anomalies without writing code.

Satellite Anomaly Detection in Time Series Data: How It Works
Anomaly detection in satellite time series identifies data points that deviate significantly from expected seasonal patterns. Learn how statistical methods flag unusual events in NDVI, SAR backscatter, and other indices — and how to distinguish real environmental events from noise.
