6 Navit is a open source (GPL) car navigation system with routing engine.
7
8 It's modular design is capable of using vector maps of various formats
9 for routing and rendering of the displayed map. It's even possible to
10 use multiple maps at a time.
11
12 The GTK+ or SDL user interfaces are designed to work well with touch
13 screen displays. Points of Interest of various formats are displayed
14 on the map.
15
16 The current vehicle position is either read from gpsd or directly from
17 NMEA GPS sensors.
18
19 The routing engine not only calculates an optimal route to your
20 destination, but also generates directions and even speaks to you.

62 Maps:
63 =====
64
65 The best navigation system is useless without maps. Those three maps
66 are known to work:
67
68 - OpenStreetMaps : display, routing, but street name search isn't complete
69 (see http://wiki.navit-project.org/index.php/OpenStreetMaps )
70
71 - Grosser Reiseplaner and compliant maps : full support
72 (see http://wiki.navit-project.org/index.php/European_maps )
73
74 - Garmin maps : display, routing, search is being worked on
75 (see http://wiki.navit-project.org/index.php/Garmin_maps )
76
77
78 GPS Support:
79 ============
80
81 Navit read the current vehicle position :
82 - directly from a file
83 - from gpsd (local or remote)
84 - from udp server (friends tracking) (experimental)
85
86
87 Routing algorithm
88 =================
89
90 NavIt uses a Dijkstra algorithm for routing. The routing starts at the
91 destination by assigning a value to each point directly connected to
92 destination point. The value represents the estimated time needed to
93 pass this distance.
94
95 Now the point with the lowest value is choosen using the Fibonacci
96 heap and a value is assigned to connected points whos are
97 unevaluated or whos current value ist greater than the new one.
98
99 The search is repeated until the origin is found.
100
101 Once the origin is reached, all that needs to be done is to follow the
102 points with the lowest values to the destination.
