Scale-dependent rendering primarily aims to improve map usability by adjusting the level of detail and the types of information displayed based on the scale at which a map is viewed. When users zoom in or out on a map, the rendering system dynamically alters what information is presented. For example, at larger scales (zoomed in), more detailed features may be visible, such as street names or smaller landmarks. Conversely, when the map is viewed at a smaller scale (zoomed out), the display simplifies the information to focus on more general features, making the map easier to interpret at a glance.

This approach enhances usability by ensuring that the map does not overwhelm the viewer with too much detail at smaller scales, while also providing important context and specifics when users are zoomed in. Thus, the focus is on creating a clearer and more effective user experience rather than merely increasing detail or adding complexity, which could lead to confusion or a cluttered appearance.
