This paper presents CrowdLOC-S, a seamless indoor/outdoor localization framework that combines crowdsourced Wi-Fi fingerprinting, GNSS, and low-cost MEMS sensors. Its design includes a data-and-model dual-driven trajectory estimator, a hybrid 1D-CNN, Bi-LSTM, and MLP quality indicator for crowdsourced trajectory evaluation and Wi-Fi database construction, transfer learning for scene switching and error prediction, and EKF-based multi-source fusion for unified meter-level positioning across complex urban environments.
