Définition
Map resolution refers to the level of detail and accuracy in a map. In other words, map resolution is how finely the map is divided into small units, such as pixels or vector data, and how accurately those units represent the real world.
For example, a map with a high resolution would have more detail and accuracy than a map with a low resolution. This can include details such as road width, building footprints, and topographical features.
The resolution of a map can depend on a number of factors, such as the scale of the map, the data sources used to create the map, and the level of generalization applied to the data.
Here are some examples to illustrate the concept of map resolution:
- A satellite image of a city may have a very high resolution, with individual buildings and even trees visible from space. This high resolution is possible because the satellite camera is capturing millions of pixels that represent a small area on the ground.
- A map of a country or region may have a lower resolution, since it is covering a much larger area. In this case, the map may use generalization techniques to represent features such as roads and buildings, which can result in some loss of detail.
- A map designed for navigation may have a high resolution at smaller scales, such as when displaying a neighborhood or city, but a lower resolution at larger scales, such as when displaying an entire country. This allows for more detailed information to be shown where it is needed most, while still providing an overview of the larger area.
Overall, map resolution is an important factor to consider when working with maps, as it can impact the level of detail and accuracy that is displayed.
