What type of services can be exposed through a map image layer?

A map image layer is designed to allow users to access and utilize map services that contain either pre-rendered images (cached map services) or dynamically generated images (dynamic map services). The core functionality of a map image layer is to present map data in a visual format, which can be generated on-the-fly based on user interaction or served as a set of pre-created, processed images that load quickly.

Cached map services are optimized for performance since they serve up images that have already been rendered and stored, allowing for rapid display and reduced load on the server. On the other hand, dynamic map services generate images in real-time, allowing for more flexibility in terms of data representation and the ability to include real-time updates.

By supporting both types of services, a map image layer offers a versatile approach to delivering geospatial data, making it invaluable for various applications that require a combination of both rapid loading times and up-to-date information, depending on user needs and system capabilities.
