overlay technology

Overlay technology involves adding new information or features on top of existing digital content or infrastructure. It allows developers to enhance or modify a system without changing its core, often by inserting extra data, interfaces, or applications that interact seamlessly with the original. For example, in digital maps, overlays are used to display live traffic, labels, or additional geographic information. This approach offers flexibility and efficiency, enabling updates or customizations without overhauling the entire system. Essentially, overlay technology acts like transparent layers that enrich or modify the underlying content in a modular and non-intrusive way.
