Algorithms for automatic semantic segmentation of the satellite images provide an effective approach for the generation of vector maps. Convolutional neural networks (CNN) have achieved the state-of-the-art quality of the output segmentation on the satellite images-to-semantic labels task. However, the generalization ability of such methods is not sufficient to process the satellite images that were captured in the different area or during the different season. Recently, the Generative Adversarial Networks (GAN) were introduced that can overcome the overfitting using the adversarial loss. This paper is focused on the development of the new GAN model for effective semantic segmentation of multispectral satellite images. The pix2pix1 model is used as the starting point of the research. It is trained in the semi-supervised setting on the aligned pairs of images. The perceptual validation has demonstrated the high quality of the output labels. The evaluation on the independent test dataset has proved the robustness of GANs on the task of semantic segmentation of multispectral satellite images.
