gpx2map
0.2


Homepage

The homepage of gpx2map is located at:
https://sethdepot.org/gpx2map


Download

The development is ongoing on Github in the master branch, Just fetch the latest version from here:
https://github.com/sd2k9/gpx2map

If you prefer having a version number or download an archive file, use the releases instead.
It could be out of date, so I suggest following the master branch instead.


Overview

gpx2map reads a gps track in GPX format (as produced by e.g. gpsbabel) and writes out an Google Map or OpenStreetMaps mash-up containing the route and additonal information. gpx2map can also show GPS-tagged photos along the map.

It comes very handy when you e.g. own an Garmin eTrex and want to know where you wandered around last time. Then you just use gpsbabel to fetch your tracks in GPX format and let gpx2map write out an map overlay for you.

Requirements

First of all Perl itself is needed, but also some packages from CPAN.
The CPAN-Modules can be found at http://search.cpan.org

Chart::Gnuplot is required for drawing the graphs. When you don't want to use this feature this package is not needed.

Image::ExifTool and convert are required for adding geocoded images to the map. When you don't want to use this feature this package is not needed.

gpx2map is likely to work also with other versions than the one mentioned here. When you encounter problems just drop me a note.


Installation

Just copy (or link) the file gpx2map into your path or any place you like.
Put the mash-up template files gpx2map.google.template and gpx2map.osm.template where you put gpx2map itself (not to the link, in case you linked it).


Operation

The input file format is GPX. You can get this e.g. by gpsbabel (gpx2map includes a shortcut for calling gpsbabel).
gpx2map then reads the GPX file and writes out a html page containing either an Google or OpenStreetMaps mash-up.

An GPX file can contain several tracks. You can select to write out only one specific track, merge all track points together or create one html file for each track.

Along the track also various graphs are generated. You can have a height graph, a speed graph, a time graph and a temperature graph.
When the data of a speed sensor is available, these values are used, otherwise average speed data is calculated.
For the temperature graph you need the Garmin tempe sensor.

When requested, GPS-tagged (so called geocoded) pictures are shown along with the track. For all supplied pictures an icon version (48x48 size, add ".ico" before the file suffix) and an shrinked version (640x640 size, add ".med" before the file suffix) are created. The icons are then placed directly on the map at the correct location. When you click these icons, the shrinked pictures along with position and time when the shot was taken are shown in an popup.
The described behaviour and defaults can be configured inside the script, see section Configuration.

In case you don't have a camera with native GPS, you can use tools like gpscorrelate to add GPS-tags to your pictures. The tool takes your GPS track, compares the track time to the time stamps of the photos and adds the correlated position into the EXIF header.


Program Options

gpx2map [--help|-h] [--version|-V] [--route|-r route] [--merge]
[--title|-t title] [--osm|-o]
[--[no]height] [--[no]tempe] [--[no]time] [--[no]speed]
[--outfile|-w file] inputfile [--pictures|-p img1 img2 ...]

--help, -h Help screen
--version, -V Version
--osm, -o Create OpenStreetMaps Mash-Up
Default is Google Mash-Up
--title, -t <title> Title of web page, when not specified use route name (or leave empty)
--route, -r <route> Route to read
--merge Use all points from all routes in gpx file
--outfile, -w <file> For --route or --merge progessing the ouput path and base filename can be given
--height|--noheight Enable (Default) or Disable height profile
--tempe|--notempe Enable (Default) or Disable Temperature profile Data provided by Garmin Tempe sensor
--time|--notime Enable (Default) or Disable Time vs. distance profile
--speed|--nospeed Enable (Default) or Disable Speed profile
--nographs Disable all profile graphs, other profile options are ignored
--pictures|-p img1 img2 ... Place a shrinked version of these images on the map
Pictures must include GPS coordinates
inputfile GPX file to read
Can be compressed with gzip, bzip2, lzma/xz

When neither --route nor --merge are specified, create individual web pages for each route.

Output is written to <inputfile_without_suffix>[.<route>].html

gpsbabel

For your convenience gpsbabel can be invoked over gpx2map. Just use the following command line:

gpx2map --babel outfile

Configuration

You can change certain settings of gpx2map operation in the header of the executable. Just search for "global settings".

Most common settings - the others are documented in the script itself:

map_line_dist
Distance between Polyline points, in kilometer
map_points_dist
Distance between mapping points in kilometer. Must be a multiple of map_line_dist
height_diff
Height difference between height diagram points in meter. The more accurate your GPS records height information, the smaller value you can use here (and vice versa)
tempe_diff
Temperature difference between tempe diagram points in grad celcius
speed_calc_dist
For manual speed calculation, update points every distance
speed_calc_TIME
For manual speed calculation, update points every time
gpsbabel_cmd
Call to gpsbabel, without output file name. The shell tokens are split up into fields.
You most certainly need to change here to use gpsbabel with gpx2map.

Examples

Have a look at my homepage for some examples:
https://sethdepot.org/site#Hiking

Please note that the maps are generated with the gpx2map version at their creation time and thus don't show all the features of the current version.


Known Issues

For picture placement to work you have to run gpx2map from the directory of the GPX file, and you cannot use absolute paths to pictures.

The browser compatibility could be improved.
gpx2map generated pages are tested sucessfully with Firefox and Chromium, with most other (older) browsers you can expect drawbacks.

OpenStreetMaps Output for Picture placement is somewhat ugly and jumpy. I am still struggeling with the API and the lack of usable examples.

To run gpx2map on windows probably have to make the following adaptions:
In the sub height_profile_image add the line: $filename =~ s{\\}{/}g;
In Gnuplot.pm, sub _execute, replace the line my $gnuplot = 'gnuplot'; with
my $gnuplot = 'C:/gnuplot/bin/pgnuplot.exe';
