Downloading and Preprocessing Sentinel SAR and Planet Multispectral Images for Flood Analysis

In this tutorial, learn the complete workflow for downloading and preprocessing Sentinel SAR images using SNAP software and multispectral images from Planet.com for flood analysis. Key Steps Covered: Subset: Crop the image to focus on the area of interest. Radiometric Correction: Apply calibration to ensure data accuracy. SAR Utilities: Perform multilooking to reduce speckle noise. Geometric Correction: Use Range Doppler Terrain Correction for spatial alignment. Raster Geometric Operations: Collocate datasets for consistency. Linear to dB Converter: Convert values to decibels for better analysis. Band Maths: Calculate custom expressions like dB/dB. Flood Analysis: Utilize preprocessed data for effective flood monitoring and management. Whether you are a beginner or an advanced user, this guide will provide practical insights to support your remote sensing projects. 🔗 Links to resources and tools mentioned: Sentinel Data Hub asf.alaska.edu/datasets/daac/alos-palsar/ vertex.daac.asf.alaska.edu/# SNAP Software https://earth.esa.int/eogateway/tools...
