TASDK Terminology

Overview

The TASDK terminology provide you with a professional terminology related to the SDK. Full text in alphabetical order.

Terminology

  1. ADAS: Advanced Driver Assistance Systems, an ADAS is a group of electronic technologies that assist drivers in driving and parking functions.
  2. AGV: Active Guidance View, a view provided by navigation when user drives along with the active route.
  3. DR: Dead Reckoning, it is the process of calculating the current position of a moving object by using a previously determined position, or fix, and incorporating estimates of speed, heading (or direction or course), and elapsed time.
  4. Edge: Edges are the most basic elements in a route and in map data.We can get information such as road type, length, etc. from edges.
  5. ERD: Elevated Route Detect.
  6. ETA: ETA is abbreviation of Estimate Time of Arrival.
  7. ETT/ETE: ETT is abbreviation of Estimate Time of Travel. ETE is abbreviation of Estimated Time Enroute
  8. Home Area: The user's Home Area is a bounding box which cover one user's main activity area.
  9. Hybrid Solution: A hybrid solution uses both onboard and cloud data to ensure drivers always have a fast, safe, and accurate experience.
  10. IGV: Inactive Guidance View, what the user sees before inputting a destination.
  11. Lane: A lane is a part of a roadway that is designated for use by single-lane vehicles to control and guide drivers and reduce traffic conflicts. Most public roads (freeways) have at least two lanes, one in each direction, separated by lane markings. On multi-lane highways and busier two-lane highways, lanes are designated with pavement markings. Major highways usually have two multi-lane roads separated by a median.
  12. Leg: The route between startpoint to waypoint; waypoint to waypoint; waypoint to destination.
  13. Maneuver Point: A set of values that specify the navigation action to take.
  14. MLD: Multiple Layer Detect.
  15. Map Matching: Map matching is the problem of how to match recorded geographic coordinates to a logical model of the real world, typically using some form of Geographic Information System.
  16. MPP: Most Possible Path, navigation suggests a path the vehicle most like will drive to in IGV.
  17. NDS: Navigation Data Standard, which is a standardized format for automotive-grade navigation databases, jointly developed by automobile manufacturers and suppliers.
  18. NGx: NGx is a Telenav exclusive database format designed along with Telenav SDK for high-performance route calculation and map rendering. It also provides rich map data attributes by covering almost all user needs.
  19. PE: Position Engine, client software running the position algorithms.
  20. Step: The segment between two maneuver points.
  21. Streaming: In MapContent working mode, it will access the new map if the queried data is overwritten in the new map. Or, if the data does not exist locally, it will download the data from the cloud asynchronously.
  22. Waypoint: A place where you stop during your journey, not the final destination.
