Modular design with routing and rendering of one or more vector maps in various formats. \

GTK and SDL user-interfaces with touch-screen displays. \

Current vehicle position from gpsd or directly from NMEA (GPS) sensors. \

Optimal routes and directions spoken in 70+ languages. \

Points of interest (POIs) in many formats.

Help and more info available on [the wiki](https://navit.readthedocs.io/en/v0.5.6/). \

The [Reporting Bugs](http://wiki.navit-project.org/index.php/Reporting_Bugs) document helps you file issues.

Maps

====

[OpenStreetMap](https://wiki.navit-project.org/index.php/OpenStreetMap) — display, routing, incomplete street-name search. \

[Grosser Reiseplaner](https://wiki.navit-project.org/index.php/Marco_Polo_Grosser_Reiseplaner) and compliant maps — full support. \

[Garmin maps](https://wiki.navit-project.org/index.php/Garmin_maps) —display, routing, search is being worked on.

GPS Support

===========

Current vehicle position from \

— a file or port. \

— gpsd (local or remote). \

— the location service of several mobile platforms. \

— a UDP server (friends tracking) (experimental).

Translation

===========

The [Hosted Weblate](https://hosted.weblate.org/projects/navit/) platform is used to manage translations, which runs [Weblate](https://weblate.org).







Routing algorithm

=================

Uses [LPA*](https://wikiless.org/wiki/Lifelong_Planning_A*) starting at the destination by assigning \

a value to each point directly connected to the destination point. \

It represents estimated time needed to reach the destination from that point. \

A Fibonacci-heap search for the point with the lowest value (to find \

a value then assigned to connected points either unevaluated or whose \

current value is greater than the new one) is repeated until the origin is found. \

Once reaching the origin, the lowest-value points are followed to the destination.

the (experimental) traffic module re-evaluates route-graph portions as segment costs change. \

It can process traffic reports and find a way around problems.
