Satellite imaging is a backbone of environmental monitoring and urban planning. State-of-the-art methodologies for image segmentation are extremely needed to process huge datasets in order to obtain substantial information out of it. This paper presents an extensive analysis on the current state of satellite image segmentation using deep learning with a special emphasis on some CNN architectures, namely InceptionResNetV2, InceptionResNetV2-UNet, Multi-UNet, VGG19, and VGG19-UNet. In this work, a number of pre-processing techniques were used namely advanced data augmentation and normalization. The set of experiments is done in the motivation to evaluate models in the best way based on a few performance metrics, such as accuracy, Dice coefficient, and validation loss among others, compared with the other models. The conducted experiments have shown that the InceptionResNetV2-UNet and VGG19-UNet provide higher segmentation accuracy compared to other models by approving a test accuracy of 89.90% and 89.41% with the dice coefficient of 85.5% and 84.9%, respectively. Further from this, proposed work introduce a Gradio-based web application for the end users to predict segmented images interactively, demonstrating real-world use cases for employed models. This bridges the gap between advanced machine learning research and satellite image evaluation, providing valuable insights for future work in this field.
