Welcome to project PaVi, an application to view GPS tracks on top of map tiles, based on library OsmGpsMap, which can download, cache and render map tiles from different web sources. As of now coding and testing gets done with tracks recorded by MapFactor Navigator software in *.NMEA and *.GPX file format.

The package is hosted at GitHub. Find further information on this project at the projects introduction page and in the online documentation.

It's a GPLv3 licensed GtkApplication with grafical user interface, command line control and DBus integration, designed to:

show a worlds map segment (tiles downloaded/cached from different web sources)
move in segment (keyboard/mouse: north, east, south, west, zoom in or out)
load recorded track[s] (*.NMEA or *.GPX file format)
plot track on map (custom color/width for lines and points)
decorate points (scaled and/or colored by elevation, speed or direction)
walk in track (map centered at the current track point)
show point data

The following screen shot shows a track ploted (by cairo) on top of OSM (Open Stree Map) map tiles by red points (60 % translucent) with variable diameter (scaled by the points elevation):

The second screen shot plots the same track on top of Virtual Earth Hybrid map tiles, complemented by a layer providing controls and point info:

Currently this project is work in progress in an early stage. Planed future improvements are:

advanced controls (keyboard and popup menues)
further command line options
replace dummy parameter dialog, save/load parameters
additional custom map sources
remember custom views (save/load: map segment, track point at map zoom)
more track customizations
track diagrams
search in track (time, position, point distance, elevation jumps, ...)
further track file formats?
finalise documentation
tiles download for off-line use
