Navit

Navit is a free navigation software for real-time navigation and GPS tracking.

The Brandenburg police is considering the widespread use of the software and tested in March 2010 to use in practice.

Functions

Navit can compute the map area around the current position in different views (orthogonal ground plan projection, perspective view ) in real time from vector map data. The design of the surface and the appearance of map features is largely configurable. Real-time images from a camera can be overlaid with, for example, route representations to a representation of augmented reality with the help of additional sensors (compass and accelerometers ) in the so-called " Reality View". The position can be read by gpsd or directly from NMEA -enabled GPS receivers. It can calculate optimum routes and current direction and thus make the route guidance via the Speech Dispatcher ( speechd ) can also be done by voice output. Routes - if necessary - even dynamically recalculated. For user input and touch screens are supported.

Availability

It is available as free software in the source code under the terms of primarily GNU General Public License (GPL ) and partly GNU Lesser General Public License ( LGPL) for a variety of operating systems. The user interface has been translated into over 40 languages ​​. In many popular Linux distributions, it can be installed directly from the standard repositories.

Navit is a major part of the navigation Live CD MUD navigation. Since February 2011, it can be related to Google Play.

Development

Development began as a private project; after some time it was put on 21 November 2005 on Sourceforge. The " Reality View " is developed together with staff from the Institute of Geography of the University of Potsdam.

Technology

The software is developed in the programming languages ​​C and C . For the representation of the graphical interface GTK or SDL is used and can be used by hardware acceleration OpenGL. The software has a modular design and is therefore easily extensible. It has been ported to various operating systems and hardware platforms, including in addition to Windows, Mac OS X and Linux also many for mobile use, as Openmoko, Nokia Internet Tablets, Zaurus, Android, iPhone and Palm webOS. For the calculation, the Dijkstra algorithm is employed. It may have different card formats can be used: in the binary format, from the OpenStreetMap project, in the format of " Marco Polo Large Travel Planner" and in Garmin card format. Navit can also be operated with any other data sets, where they may be placed in one of the supported vector map data formats.
