latitude

Latitude
  • Description: geographic coordinate that indicates the position along the Earth’s north-south axis
  • Format: numeric
  • Unit: °
  • Decimal places: 7
    • Data processed by mobway will always have up to 7 decimal places. However, the precision of the original data depends on the automaker. The data may have fewer than 7 decimal places when it ends in 0 due to automatic float formatting
  • Range: -90° to 90°
    • The latitude range was defined based on the boundary values by definition
    • Data outside this range is considered invalid
    • The value is replaced with a null value
    • A flag is generated indicating the error and the original value, in the following format:
{
  "latitude": {
    "value": 93.7435821,
    "flag": "out of range"
  }
}
  • Minimum and maximum variation: - 0.001° and 0.001° per second
    • The minimum and maximum latitude variations were defined based on the distance traveled by a vehicle at 400 km/h, considering a trajectory along the Earth’s north-south axis and applying a safety margin
    • Data with a variation outside the allowed limit compared to the previous data point is considered invalid
    • The value is replaced with a null value
    • A flag is generated indicating the error and the original value, in the following format:
{
  "latitude": {
    "value": 14.3181722,
    "flag": "variation out of limit"
  }
}
  • Missing data
    • A flag is generated indicating that the data was originally missing, in the following format:
{
  "latitude": {
    "flag": "missing data"
  }
}
  • Example:
{
  "latitude": 34.0567236
}

​
longitude

Longitude
  • Description: geographic coordinate that indicates the position along the Earth’s east-west axis
  • Format: numeric

  • Range: -180° to 180°
    • The longitude range was defined based on the boundary values by definition
    • Data outside this range is considered invalid
    • The value is replaced with a null value
    • A flag is generated indicating the error and the original value, in the following format:
{
  "longitude": {
    "value": -191.3564382,
    "flag": "out of range"
  }
}
  • Minimum and maximum variation: - 0.001° and 0.001° per second
    • The minimum and maximum longitude variations were defined based on the distance traveled by a vehicle at 400 km/h, considering a trajectory along the Earth’s east-west axis and applying a safety margin

    • The value is replaced with a null value
    • A flag is generated indicating the error and the original value, in the following format:
{
  "longitude": {
    "value": 43.8127712,
    "flag": "variation out of limit"
  }
}
  • Missing data
    • A flag is generated indicating that the data was originally missing, in the following format:
{
  "longitude": {
    "flag": "missing data"
  }
}
  • Example:

​
altitude

Altitude
  • Description: vehicle elevation relative to sea level
  • Format: numeric
  • Unit: m
  • Decimal places: 2
    • Data processed by mobway will always have up to 2 decimal places. However, the precision of the original data depends on the automaker. The data may have fewer than 2 decimal places when it ends in 0 due to automatic float formatting
  • Range: -500 to 9000 m
    • The altitude range was defined based on the boundary values found on Earth
    • Data outside this range is considered invalid
    • The value is replaced with a null value
    • A flag is generated indicating the error and the original value, in the following format:
{
  "altitude": {
    "value": 11191.32,
    "flag": "out of range"
  }
}
  • Minimum and maximum variation: - 30 m and 30 m per second
    • The minimum and maximum altitude variations were defined based on the distance traveled by a vehicle at 400 km/h, considering a 15° slope and applying a safety margin
    • Data with a variation outside the allowed limit compared to the previous data point is considered invalid
    • The value is replaced with a null value
