Visualizes GPS information. Features points of interests, wayfinding (without a map) and a cool visual radar overview. Great for geocaching, not so great for driving.

This Application is intended for use as a simple Geocaching tool.
It has functionality roughly equivalent to a low cost handheld
GPS receiver. You can use it to find your way towards
any point given in GPS coordinates or imported from a GPX file.
This application is not supposed to be used for car navigation,
as it only tells you the direction in which the target position
lies relative to your current position and the distance,
it doesn't take into account any map data.


For non Arch Linux users:
   python >= 2.6 (3.0 is not backwards compatible so < 3.0)
   gpsd > 2.94  (version 2.94 has a broken python interface)
   pygtk >= 2.17.0 (earlier versions might work but haven't been tested)
   run as root: 'python install'
   you can use the options listed under 'python --help install'
   and 'python --help'
For Arch Linux users:
      Get lotse from AUR
   To build from git:
   run 'python sdist'
   get the md5sum of dist/lotse-*.tar.gz and put it into the PKGBUILD
   then run 'makepkg -cf' and install 'pacman -U lotse-*.pkg.tar.xz'

How to use it

First you need to make sure that gpsd is running, this is crucial
as lotse will only show an error message and quit if gpsd is not
running on your computer. Refer to 'man gpsd' or other adequate
documentation on how to get gpsd up and running.
You should then check whether gpsd is running correctly by issuing
'xgps' this should give you some info about your GPS, you might
need to install 'gpsd-clients' depending on your distribution.


You can launch lotse from the menu (it should be under 'Accesories')
or you can run 'lotse' from the command line.

Going to coordinates:
First, you need to create a waypoint for your target, so go to the
Waypoint tab.
If you have a GPX File (for example from your Geocaching Website) you
can just click on import, choose the file and then select the waypoint
you want to go to. (You need to highlight it and then click 'select')
If you have the coordinates for example on paper or as text, copied from
some place, you need to click 'Add', this will create an 'Unnamed'
waypoint defaulting to your current position.
Click on the lat/lon field and enter your coordinates, the way you have 
written them down, chances are lotse will interpret them correctly.
Supported formats include (but aren't limited to):
   48° 45′ 20.6″ N, 9° 11′ 24.8″ E
   48.755722°, 9.190222°
Then highlight the waypoint and click 'select' switch to the Goto tab,
the black arrow points to the target while the red arrow indicates north
your walking direction is always up on the display.
Note, that GPS can only calculate your heading 
(the direction you are walking in, while you are not standing still).
Tip: If you have a compass you can use the target 'Direction'

Advanced use of the 'Radar'
You can left click on the radar for a context menu, with which you
can create a new waypoint at the location your mouse would be
when translated to real world coordinates, or select the nearest

Creating a GPX Log
To create a GPX log you can use the Log tab, remember to
end the filename with .gpx
