## Overview

The commonly used coordinate systems include the world coordinate system, the vehicle coordinate system, and the sensor coordinate system.

- The world coordinate system is a fixed coordinate system that defines the physical space in the environment where the vehicle is located.

## How they can be created

1. Calibration of sensor

The conversion relationship between every sensor coordinate system and `base_link` can be obtained through sensor calibration technology. How to calibrating your sensors refer to this link [calibrating your sensors](https://autowarefoundation.github.io/autoware-documentation/main/how-to-guides/calibrating-your-sensors/).

2. Localization

The relationship between the `base_link` coordinate system and the `map` coordinate system is determined by the position and orientation of the vehicle, and can be obtained from the vehicle localization result.

3. Georeferencing of map data

The georeferencing information can get the transformation relationship of `earth` coordinate system to local `map` coordinate system.
