Node in OpenStreetMap refers to a point of interest on a map. It can be any point on a map that has a unique location, such as a building, a statue, or a tree. Nodes are a fundamental building block of OpenStreetMap data, and they are often used to create more complex objects like ways and areas. In simpler terms, a node is a dot on a map that represents a specific location or feature. It is typically used in conjunction with other nodes and lines to create more complex objects like roads, buildings, and parks.

For example, imagine you are creating a map of a city park. You might start by adding nodes to represent the location of trees, benches, and other points of interest in the park. You could then connect these nodes with lines to create paths and trails, and add labels and icons to provide more information about each feature.

In OpenStreetMap, nodes are represented using a unique ID number, which allows them to be easily referenced and linked to other objects on the map. They can also be tagged with additional information, such as the name of a building or the type of tree at a particular location.

Some examples of nodes on an OpenStreetMap map might include:

  • A point representing a restaurant or cafe
  • A marker indicating the location of a historical monument or landmark
  • A dot showing the position of a bus stop or train station
  • A symbol indicating the location of a restroom or water fountain in a park.

Overall, nodes are a crucial component of OpenStreetMap data and are used to represent a wide range of features and points of interest on a map.
