What are "anomalies" in remote sensing data?

Anomalies in remote sensing data refer to irregularities or deviations from expected patterns. This concept is crucial in various applications, including environmental monitoring, agriculture, and disaster response. Anomalies are often indicative of changes or events that deviate from the norm, such as alterations in vegetation health, unexpected temperature fluctuations, or anomalies in land use. Identifying these irregularities assists scientists and decision-makers in diagnosing issues, tracking changes over time, or determining areas that require further investigation.

While other options mention patterns, conditions, or monitoring, they do not capture the essence of what an anomaly represents in the context of remote sensing. Anomalous data points are significant because they can signal underlying problems or unique phenomena that may warrant further analysis and action.
