If you are a serious jogger | hiker | bicyclist, there's a good chance that you want to improve and to be better than the last outing. But how? You analyze your track data, of course. You need a GPS device that can log in GPX format first, your Android can do that. These 4 applications will help you analyze your track data, that was logged by GPS.

1. Google Earth
   the most simple of all, it only plots your track data on satellite photo, with no analyzing whatsoever, not even distance and duration.
   Here's how to install Google Earth on Ubuntu.
   
2. Andrew Gee's GPX Viewer
   GPX Viewer is an application that allows users to easily view GPS traces they have created in the GPX file format. It plots the track on openstreetmap and shows distance, average speed, maximum speed, duration.
   You must add the PPA before installing it.
   
3. Viking (already available at Ubuntu repository)
   GPS Data and Topo Analyzer, Explorer, and Manager. Not so much in analyzing but it can shows speed profiles over distance.
   
   
   
4. Qball Cow and Andrew Harvey's GPX Viewer (only available in source)
   is simply the best.
   
   This application features :
   
   • Show multiple GPX files.
   • Show waypoints and multiple tracks per gpx file.
   • Highlight selected track.
   • Show distance, duration, average, moving average, max speed, moving time and gps points.
   • Zooming
   • Smoothing of speed graph.
   • Highlighting points in speed graph on map.
   • Show time vs.  height graph, speed,  acceleration (hori/verti), distance, etc.
   • Playback of a track.
   • Show track on different types of maps (depends on support in libchamplain)

Unfortunately there's no .deb file nor PPA for easy installing on Ubuntu. You must compile it first, I wrote how to compile GPX Viewer on Ubuntu here.

There you go, 4 application to help you be a better jogger | hiker | bicyclist, have fun outdoor!

GPX Viewer by Qball Cow and Andrew Harvey is the best track | gpx analyzer so far that run on Ubuntu, there's another GPX Viewer by Andrew Gee which is too simple for my need. Unfortunately there's no .deb file nor PPA for easy installing on Ubuntu.

Here's how I installed GPX Viewer on my Ubuntu 10.04. Command Line involved :)

1. Download the GPX-Viewer source file here
2. extract it, for example in your home directory /home/your username/source/GPX-Viewer-version
3. open the terminal, you are already in your home directory, go to the folder by typing this command : cd /source/GPX-Viewer-version
4. After that run ./configure this command will configure your installation files and checks for any error
   in my case I have this error message (with my emphasis):

...

configure: WARNING: No Vala compiler found.  You will not be able to compile .vala source files.
checking for pkg-config... /usr/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
checking for modules... configure: error: Package requirements (
        gtk+-2.0  >= 2.16
        champlain-gtk-0.4 >= 0.4.3
        champlain-0.4 >= 0.4.3
        gmodule-2.0
        libxml-2.0
        gdl-1.0
        unique-1.0
        ) were not met:

No package 'champlain-gtk-0.4' found
No package 'champlain-0.4' found
No package 'gdl-1.0' found
No package 'unique-1.0' found

this error shows that I have to install somethings else first, your mileage may vary though.

5. go to synaptic package manager, from the error message (bolded font, my emphasis) , I know I have to install:

   • No Vala compiler found -> install libvala-dev and valac
   • No package 'champlain-gtk-0.4' found -> install libchamplain-gtk-0.4-dev
   • No package 'champlain-0.4' found -> install libchamplain-0.4-dev
   • No package 'gdl-1.0' found -> install libgdl-1-dev
   • No package 'unique-1.0' found ->install libunique-dev
      
     

6. run ./configure again to see if any error comes up, if everything okay proceed to next step

7. run make
8. run sudo make install (you may have to input your password here)
9. done find it on Start Menu > Accessories

Lately my Android phone and my Ubuntu laptop are getting more friendly.

I am a photography enthusiast with Nikon D70s, this camera is not GPS-ready and even if it did I have no intention to buy an expensive GPS attachment. So here's what I did :

1. Install GPS Logger for Android via Market application. This app will log your photo-walk in pre-determined time or distance. The log data stored in SD card in  .GPX and .KML formats.
   
2. Make sure to synchronize the clocks in your camera and your phone first,
3. Start the application and wait until it gets satellites coverage before you take photos, 
4. Download your photos and the .GPX log to your computer,
5. In your computer start your geo-tagging software. Load the photos and the log file, and your photos will be geo-tagged automatically.
   open digiKam, it already includes geotagging application, just go to Image -> Geolocation -> Correlator
6. add the recently shot images and then load the .GPX file, adjust the time difference accordingly -> apply
   
7. Done
