===== Idea =====

Idea is to creat (very) simple application that can mark your position on a map using GPS. In future you could sync other peoples position to your phone (Not implementing in this session).

  * Main idea; simple gps tracker which gives users position on the map.
  * Coding language Python
  * Should work on LUT campus area
  * Gives gps data to the workers on 8th building phase construction site

===== Workflow =====

**15.00-18.00**: Making development tools to work. Configuring development tools and phone to accept python.

**18.00-00.00**: Coding basic GPS functions.

**00.00-03.00**: uploading image file

**03.00-08.00**: zzZZzzz

**08.00-10.30**: implementing drawing primitives (dropped)

**10.30-13.59**: Implementing location warning and tweaking GPS coordinate conversion

**13.59-14.00**: Wrinting wiki and slides ;)


===== Implementation =====

Code was done using pymaemo (python designed for maemo that uses gtk for layout management). GPS coordinate conversion to distance was done using formula found from the
[[http://cyberpython.wordpress.com/2010/03/31/python-calculate-the-distance-between-2-points-given-their-coordinates/|web]].


===== Features =====

Priorities: First priority (1), implemented if enough time (2)

^Feature ^ Priority ^ Status |
|GUI|1|Done|

===== Conclusion =====

● Maemo didn't have good python libraries to draw image layers.

● Layout was quite tricky to make (still not what we
wanted).

● GPS was hard to debug because connetions
to satellites can't be made inside. Maemo Xephyr couldn't emulate GPS easily.

● Scratchbox wasn't all too useful. It broke down once and Xephyr can't be rebooted without using command-line. 

● Python hugely fastened development.
