What does a map service do?

A map service primarily functions to deliver rendered map images, which can be displayed in various applications without requiring direct interaction from the user. This type of service is essential in web mapping applications, as it allows end-users to view geographical information quickly and efficiently without having to process or generate the data themselves on their devices. Users can simply load the service into their applications, and the server takes care of rendering the map, which significantly improves performance and reduces data load on client devices.

This fundamental characteristic distinguishes map services from other options. For instance, while interactive data visualization tools require direct user input and manipulation, a map service operates in the background, presenting users with static images based on underlying data. Similarly, analytical report generation and the manipulation of layers by end-users pertain more to other types of services or user interfaces that support interactivity and data analysis rather than the straightforward delivery of rendered maps.
