Sentinel-1 Coherence Estimation for Addis Ababa | SAR/InSAR Analysis

Learn how to estimate and visualize Sentinel-1 SAR coherence for Addis Ababa, Ethiopia. In this tutorial, you will learn how to: • Prepare a pair of Sentinel-1 SAR images • Align the images for coherence analysis • Estimate interferometric coherence • Generate and display the coherence raster • Interpret areas of high and low coherence • Analyse spatial variations across Addis Ababa Coherence values range from 0 to 1. Higher values generally indicate stable surfaces with similar radar responses, whereas lower values may indicate surface change, vegetation movement, water, temporal decorrelation or image misalignment. This workflow is useful for urban monitoring, land-cover change analysis, infrastructure assessment, disaster mapping and InSAR applications. for more contact via seifamichael‪@gmail.com‬ #coherence #sentinels #video #remotework #viral
