What are Locator maps primarily used for?

Locator maps serve the purpose of providing a simplified overview of specific, smaller geographic areas such as towns, islands, or specific attractions. They typically highlight significant features, including major hotels and points of interest, which makes them particularly useful for travelers who need to orient themselves within a smaller context. This type of map is designed to show critical landmarks and help users quickly grasp the layout of an area, enhancing their ability to navigate and plan their itineraries effectively.

The other options involve broader geographic or economic features that locator maps do not specifically address. Representing large geographic regions or political borders would entail more detailed maps that provide comprehensive visual information on extensive areas or jurisdictional lines rather than focusing on localized points of interest. Mapping out trade routes and shipping lanes pertains more to logistical and transportation planning, which requires different kinds of maps designed for that specific purpose.
