Urban Areas are continuously expanding and accelerating urbanization while detection these areas provide useful information and can be helpful for decision makers. Urban Builtup Area Extraction is one of the useful topics that can be used in many projects. in this video, we firstly show you how to preprocess Sentinel1 images Radiometrically & Geometrically such as Thermal Noise Removal, Calibration, Radiometric Terrain Flattening, Multilooking, Speckle reduction, Range doppler Terrain correction, etc. After preparing the Sentinel1 image, Builtup area can be detected more or less due to its high backscatter. Secondly, we classify the Sentinel1 image to properly extract Builtup areas. To classify the image we've utilized Random Forest Classification, but you can use other methods as well. All the processing have been performed in the SNAP software which is one of the powerful software in processing Sentinel images. Ask your questions in the comment if you want.
