Outdoor navigation using GPS is reliable in open environments but fails inside buildings where satellite signals are weak or unavailable. This creates difficulties in large infrastructures such as hospitals, malls, airports, and university campuses. To address this, we propose a hybrid indoor-outdoor navigation system that enables a smooth transition between outdoor and indoor navigation. The system uses OpenStreetMap (OSM) for outdoor routing, providing an open-source and cost-effective alternative to proprietary mapping services. For indoor navigation, building floor plans are processed using Optical Character Recognition (OCR) to extract meaningful information such as room names and directions, which are then converted into navigable paths. The system also implements role-based access, allowing owners to add or update locations, while users can search and navigate to desired destinations. By integrating outdoor GPS navigation with OCR-enabled indoor guidance, the proposed approach offers a scalable, user-friendly, and practical solution for real-world navigation challenges.
