A method for generating an electromagnetic-profile digital map creates a visual map that includes all obstacles on the road, including road textures, other vehicles, and more. This is achieved by collecting data from specialized deployed vehicles for subsequent processing and compilation. The generated electromagnetic-profile digital map provides three dimensional geographic characteristics of a road, thus enabling automatic driving. The method further utilizes artificial intelligence technology that can improve an autopilot role in automatic driving. Electromagnetic (EM) profiles acquire and analyze data to provide powerful tools for various wireless vehicular communication services. The method utilizes both compiled digital geographical characteristics (location, road futures, including curvature, condition, and more), and surrounding features (3D images, elevations, traffic light location, speed limit, EM propagation profile, and more) to render road conditions. Machine learning patterns are utilized to update the EM propagation profile map.
