 Map matching typically involves comparing the sensor data, such as GNSS or inertial sensor data, with the digital map data. The sensor data is typically in the form of a series of GNSS coordinates or inertial measurements, while the digital map data is typically in the form of a vector map, which represents the roads and other features in a geographical area.
 
 **The process of map matching involves several steps:**
+
 **-   Data pre-processing:** This step involves cleaning and preparing the sensor data and digital map data for the map matching process.
     
 **-   Candidate generation:** This step involves generating a set of possible locations on the digital map that correspond to the sensor data.
